Translate the sentence into an inequality.
Twice the difference of a number and 5 is at most 27.
Use the variable b for the unknown number.
Answers
Answer:
2b-10≤27
Step-by-step explanation:
In this problem, we use b to represent the unkown number. Please be careful of order of operations when writing the inequality. (The difference of a number and 5) multiplied by 2 is at most 27. Also, note that the both sides of the inequality can be 27, but no more than 27.
[tex]2(b-5)\leq 27\\2b-10\leq 27\\[/tex]
If you wish to solve for b from here, simply isolate the term containing b and solve from there.
I hope this helps! Let me know if you have any questions :)
Answer:
2(x - 5) < 27
Step-by-step explanation:
Equation
2(b - 5)<27
Explanation
Break this down
difference means subtract.
The number is b
and finally for now, the difference between a number and 5 is
x - 5
Twice that difference is
2(x - 5)
And the keyword less (than) 27. Always make sure you know what less than means. It means that it is never equal to 27, but it can be pretty close.
26.999999999999 < 27
So the final result is
2(x - 5) < 27

Step-by-step explanation:
x=y=75°
y+30=z
105=z
!!!!!!!!!!
Answer:
x = 75 degree , y = 75 degree , z = 105 degree
Step-by-step explanation:
x = 75 degree (being corresponding angles)
x=y (being corresponding angles)
75 = y
substituting the value
y + 30
75 + 30
105 degree
z = y + 30 (being corresponding angles)
z = 105 degree

Find the 25th term of the sequence -7,-22,-37.
Answers
Answer:
a₂₅ = - 367
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 22 - (- 7) = - 37 - (- 22) = - 15
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 15 , then
a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

Answers
9514 1404 393
Answer:
perimeter: 36 +16√5 ft ≈ 71.777 ftarea: 288 ft²Step-by-step explanation:
Perimeter
The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5
Then the perimeter is ...
P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet
__
Area
The area is given by the formula ...
A = bh
where b is the base and h is the height.
A = (18 ft)(16 ft) = 288 ft²

If m angle RTS = 8x + 18, find x so that line TR is perpendicular to line TS
Answers
Answer:
Point T is the right angle of the triangle, so RTS = 90 degrees
8x + 18 = 90 (degrees)
8x = 72
x = 9 degrees
Step-by-step explanation:
If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].
What is perpendicular ?A line is said to be perpendicular to another line if the two lines intersect at a right angle i.e. make [tex]90^0[/tex] angle with that line.
We have,
[tex]\triangle RTS[/tex] in which,
[tex]\angle RTS=8x+18[/tex]
Also it is mentioned that [tex]TR \perp TS[/tex] i.e.
[tex]\angle RTS=90^0[/tex]
So, compare values of [tex]\angle RTS[/tex],
We get,
[tex]8x+18=90[/tex]
[tex]8x=72[/tex]
[tex]x=9^0[/tex]
Hence, we can say that If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].

what is the value of "m" if m% of it is 49?
Answers
The answer is in the picture. Click on it
The value of "m" if m% of it is 49 will be 70.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
A percentage is a minimum number or ratio that is measured by a fraction of 100.
WE need to find the value of "m" if m% of it is 49.
We have been an expression as;
m x m% = 49.
Solving further;
m x m/100 = 49.
m² / 100 = 49
Now, Cross multiplication;
m² / 100 = 49
m² = 4900
On taking square root;
m = √4900
m = 70
Therefore, the value of "m" if m% of it is 49 will be 70.
