the temperature differential is based on the numbers on a line with the negative numbers left of zero and the positive numbers right of zero.
Using -12 on the number line, add 25 to it to get the noon temperature tomorrow.
Awnser -12 + 25 = 13
The temperature tomorrow at noon will be 13 degrees.

Dilation:
The dilation factor is the length of image/preimage = 1.5
Thus
Q'R'/QR=1.5
Q'R'=1.5QR = 1.5 (5 cm) = 7.5 cm

Answer:
x < 2
Step-by-step explanation:
Given
5 + 2x < 9 ( subtract 5 from both sides )
2x < 4 ( divide both sides by 2 )
x < 2
Answer:
x=53
x+2= 53+2= 55
Step-by-step explanation:
(x+2) + x + 72 = 180 (angles of triangle supplementary)
2x+ 74 = 180
2x = 180- 74
2x= 106
x= 106/2
x= 53
