Answer:
1) x= -1/27
2) x=-4
3) x=13
Step-by-step explanation:
1) 7+7/9x= = -42
14/9x= = -42
14/9x X 9x= -42 X 9x
14= -378x
-378x= 14
-378x/-378= 14/-378
x= -1/27
2) 4x+1=−15
4x+1-1=-15-1
4x=-16
4x/4= -16/4
x=-4
3) −4(x−3)=−40
-4(x-3)/-4= -40/4
x-3=10
x-3+3=10+3
x=13

What was the change it point value from missed
questions and extra credit? Write your answer
as an integer.
Answer:
-7
Step-by-step explanation:
She lost 12 points, 3 * 4 = 12, and she gained 5 points, so -12 + 5 = 5 - 12 = -7

Which of the following are needed to make an expression?
A. variable(s)
B. number(s)
C. equal sign
D. operation(s)
Answer:
variables is the correct answer
Answer:
ALL OF THE ABOVE
Step-by-step explanation:
An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.
It can be all of the above too. because everything is needed to make an expression.

[Help Please!] Find the value of x.
Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.
Please help!!!!!!!!!!!!!!!!!!!!
Answer:
4. alternate exterior angles
5. 4.5
Can you plzz find the width...and give steps
Answer:
12
Step-by-step explanation:
We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.
Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520
So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3
Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.
We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or
11,520/(40*24) = 11,520/960 = 12
Her chest is 12 inches wide

[tex] \frac{1}{5} \times 5 = \frac{1}{5} \times \frac{5}{1} \\ \\ \frac{5 \times 1}{5 \times 1 } = \frac{5}{5} = \frac{1}{1} = 1[/tex]
Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5
Answer:
C. y = 1/2x + 5
Step-by-step explanation:
For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.
For D. it doesn't even have x in it, so basically y equals a number.
C. is a linear equation, y = 1/2x + 5

Kenna's bedroom is 12 feet long by 8 feet long. Her parents have agreed to buy new carpet for the entire bedroom.The carpet costs $15 per square meter. What will be the total cost of the new carpet? 1 foot = 0.305 meter
A. $439.20
B. $54.90
C. $133.96
D. $91.50
Answer:
C. $133.96
Step-by-step explanation:
Convert units:
12 · 0.305 = 3.66 m
8 · 0.305 = 2.44 m
Find the area of the room:
3.66 m · 2.44 m = 8.9304 m²
Find the cost:
8.9304 · 15 = 133.96
The following triangle is an isosceles triangle. What is the length of the missing side?
A. 4 in
B. 37°
C. 53°
D. 11 in
Answer:
D.11 in
Step-by-step explanation:
isosceles triangles have two congruent sides
The missing side length is congruent with the longer side ( this is pretty obvious )
If the longer side has a length of 11in and the missing side is congruent to the longer side then the missing side length equals 11 in

Answer:
The numbers are 8 and 6
Step-by-step explanation:
Let x and y be the two numbers
x+y = 14
x-y = 2
Add the two equations together
x+y = 14
x-y = 2
--------------
2x +0y = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 14
8+y =14
Subtract 8 from each side
8+y-8 =14-8
y =6
The numbers are 8 and 6
Answer:
8 and 6
