5 less than a number is equivalent to 1 more than three times the number.
Answers
The value of the unknown number is calculated as - 3
Let the unknown number = y
5 less than the number is written as = y - 5
1 more than three times the number is written as = 1 + 3y
Since the first statement and the second statement are equal, we can equate the two and solve for y.
y - 5 = 1 + 3y
collect similar terms together
y - 3y = 1 + 5
-2y = 6
y = -6/2
y = -3
Therefore, the number is - 3

(05.01) A window is 4 feet and 8 feet tall. A manufacturer wants to use a scale factor of 1.5 to enlarged a window. What will the area of the wind will be after it is enlarged?
Answers
Answer:
the window would be 72ft²
Step-by-step explanation:
A window is rectangular in shape.
the area of a rectangle is give as length * breadth
but this question say that the manufacturer wants to enlarge the window by 1.5
therefore we are going to multiply the length by 1.5 and the breadth also by 1.5 to get the new area of the bigger window.
length = 8 * 1.5
= 12
width = 4 * 1.5
= 6
The new area would be = l * b
= 12 * 6
= 72ft²

Answer:
3rd option is correct
Step-by-step explanation:
If the table represents a function, that means that it is proportional. But the value increases and decreases, showing no proportional relationship.
So, the answer could be 1st or 3rd as they tell that the table doesn't represent a function.
1st answer says the table doesn't represent a function because the 2 (y-values) are similar;
Their x-values are different so, this answer is wrong.
3rd answer says that the table doesn't represent a function x-value increases, while y-value increases and decreases;
The statement is correct because it this table doesn't represent a proportional relationship as its y-values are increasing and decreasing while its x-values are only increasing.
So, the 3rd option is correct.
A rectangle has an area of 21x+81. If the width is 3 units, what is the length of the rectangle
Answers
Answer:
(7x + 27) units
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides) in which opposite sides are equal and parallel, also all the angles are equal. The area of a rectangle is given as:
Area = Length × Width
Given that the area of the rectangle is 21x + 81 and the width is 3 unit, to find the length of the rectangle, we have to use the formula of the area and then get the length. Therefore:
Area = Length × Width
21x + 81 = Length × 3
Length = (21x + 81) /3
Length = 7x + 27
The length of the rectangle is 7x + 27 units

Jackson's rectangular bedroom has an area of 90 sq ft. The area of his bedroom is 9 times that of his rectangular closet. If the closet is 2 ft wide, what is it's length?
Answers
Answer:
5 feet
Step-by-step explanation:
Since Jackson's bedroom is a rectangle, it has dimensions of length times width. Suppose the length is l and the width is w.
The area of a rectangle is given by A = lw, where l is the length and w is the width. Here, we know the area is 90, so:
lw = 90
We also know that this area of 90 square feet is 9 times that of the closet, so suppose the area of the closet is c. Then:
9c = 90
Divide by 9:
c = 90/9 = 10 square feet
So, the area of the closet is 10 square feet. Since the width is 2, we know the length will be:
A = lw
10 = lw
10 = 2 * l
l = 10/2 = 5
The length is thus 5 feet.
~ an aesthetics lover
Answer:
5 ft
Step-by-step explanation:
If his bedroom is 9 times of his closet, then that means you divide the area of his bedroom by 9. So, 90 divided by 9=10. That means the closet has an area of 10 sq. ft. As we all know, the area is the length times width. So if the width is 2 ft, then we need to multiply it by a number so it will equal 10. You can do 10 divided by 2 to find it, which equals 5. That means the length of the closet is 5 sq. ft.

Rochelle deposits $6,000 in an IRA. What will be the value (in dollars) of her investment in 15 years if the investment is earning 9% per year and is compounded continuously? (Simplify your answer completely. Round your answer to the nearest cent.)
Answers
Answer:
$ 23,145
Step-by-step explanation:
This is a compound interest question where the interest is compounded continuously. Hence, the formula for the value of total amount of investment is:
A = P×e^rt
Where:
A = Total value of investment after t years
P = Principal or Initial amount invested = $6,000
e = Exponential function
r = interest rate = 9% = 0.09
t = time in years = 15
So:
A = $6000 × e^15 × 0.09
A = $6000 × e^1.35
A = $23,144.553184
Approximately , A ≈$23,145
Therefore, the value (in dollars) to the nearest cent of Rochelle's investment in 15 years if the investment is earning 9% per year and is compounded continuously is $23,145.

Answers
Answer:
117°
Step-by-step explanation:
Arc ABC (AB + BC) is intercepted by angle D.
Therefore, Arc ABC is 2 × m<D. (Inscribed Angle Theorem)
AB = 91°
m<D = 104°
Let BC = x
Arc ABC = (91° + x)
Thus,
91° + x = 2 × 104°
Solve for x
91 + x = 208
Subtract 91 from both sides
91 + x - 91 = 208 - 91
x = 117
Measure of arc BC = 117°

What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle.Properties of an Isosceles Triangle
Here is a list of some properties of isosceles triangles:
In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal.In the isosceles triangle given above, the two angles ∠B and ∠C, opposite to the equal sides AB and AC are equal to each other.The isosceles triangle has three acute angles, meaning that the angles are less than 90°.The sum of three angles of an isosceles triangle is always 180°. Types of Isosceles TrianglesGenerally, isosceles triangles are classified into three different types:
Isosceles acute triangle: An isosceles acute triangle is a triangle in which all three angles are less than 90°, and at least two of its angles are equal in measurement. Isosceles right triangle: The following is an example of a right triangle with two legs (and their corresponding angles) of equal measure. Isosceles obtuse triangle: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.Therefore, set of integers represents the lengths of the sides of an isosceles triangle {6,6,5}.

15 x = -27 + 6x cuál es la respuesta de la ecuación, ¿me ayudan? gracias!
Answers
Answer:
x = -3
Step-by-step explanation:
If the equation is correctly written as 15·x = -27 + 6·x
Then we have;
15·x = -27 + 6·x
We subtract 6·x from both sides to have all the variables (x) on one side as follows;
15·x - 6·x= -27 + 6·x - 6·x
Which gives;
x·(15 - 6) = -27 + x·(6 - 6)
We note that 6 - 6 = 0, therefore, we have;
x × 9 = -27 + x × 0
We not that x × 0 = 0, therefore;
x × 9 = -27
We now divide both sides with the 9 to get the value of x alone as follows;
x×9/9 = -27/9
Which gives;
x = -27/9 = -3
x = -3
a number has 2,5 and 7 as its prime factors. what are the four smallest values it and take
Answers
Answer:
70, 140, 280, 350
Step-by-step explanation:
Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.
Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...
So, the four smallest numbers with prime factors of 2, 5, and 7 are ...
70 = 2·5·7
140 = 2²·5·7
280 = 2³·5·7
350 = 2·5²·7

I can't give a full answer because I can't see the image whilst giving an answer but I'll try so....
Step-by-step explanation:
Angles in a straight line add to 180° so when you have one of two of them angles are them together and take away from 180°
Angles around a full point add to 360° so add angles together and take away from 360°
On A I think it is you have a 360° angle and have to work out 3 and you have one already done and the opposite angle is the same as that so you basically have two angles then you add them together then take from 360 then divide the answer by two and then that would be the angles for a and x
And for the last one you have been given two angles with a right angle and a right angle equals 90 so add them together and take from 180 to get the missing angle

Subtract 63
63 +7x -63 = 84-63
7x =21
Divide by 7
7x/7 = 21/7
x = 3
KM = x+2+7
= 3+2+7
=12
Answer:
[tex]\huge\boxed{KM = 11}[/tex]
Step-by-step explanation:
According to secant - secant theorem:
(MK)(ML) = (MR)(MN)
Where
MK = 7 + x+ 2 = x + 9
ML = 7
MR = 8 + 6 = 14
MN = 6
=> (x+9)(7)= (14)(6)
=> 7x + 63 = 84
Subtracting both sides by 63
=> 7x = 84 - 63
=> 7x = 21
Dividing both sides by 7
=> x = 3
Now,
KM = x + 9
KM = 3 + 9
KM = 11
