Answer:
A: x = 20
C: x = -9
Step-by-step explanation:
You can solve the inequality and compare that with the offered choices, or you can try the choices in the inequality to see if it is true. Either approach works, and they take about the same effort.
<u>Solving it</u>:
Unfold it ...
-17 ≤ x -7.5 ≤ 17
Add 7.5 ...
-9.5 ≤ x ≤ 24.5
The numbers 20 and -9 are in this range: answer choices A and C.
_____
<u>Trying the choices</u>:
A: |20 -7.5| = 12.5 ≤ 17 . . . . this works
B: |-10 -7.5| = 17.5 . . . doesn't work
C: |-9 -7.5| = 16.5 ≤ 17 . . . . .this works
D: |27-7.5| = 19.5 . . . doesn't work
The choices that work are answer choices A and C.
Answer:
-169 degrees
Step-by-step explanation:
It doesn't make much sense... but let's answer the question anyway.
First task is to determine what's the temperature outside at 2:30 PM.
We know that it's 11 degrees cooler than it was at 7 AM, so -4 - 11 = -15 degrees.
Abram's house is 4 degrees less than 11 times the outside temperature, so we can express that as:
House = 11 x - 4 - where x is the temperature outside.
If we replace the numbers we get: 11 * (-15) - 4 = -165 - 4 = -169 degrees
Abram's house is an extremely cold freezer!
