Answer:
A
Step-by-step explanatiWe know x is between 1 and 3 so the best estimate is 2 even though the answer could also be 3 but that will be skewed.
Answer:
Hello,
-5(-x + 1) -3x -1 = -12 ⇔ 5x - 5 - 3x - 1 = -12 ⇔ 2x - 6 = -12 ⇔ 2x = -6 ⇔ x = -3
Option D x = -8 is correct option.
Step-by-step explanation:
We need to solve the inequality:
Solving:
All the values less than 7 are included in the number line.
The graph on number line is shown in figure attached.
In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
while Option D is less than 7 so, x=-8 is correct
Option D is correct.

I'm assuming you want help with numbers 7 and 8 because multiplication should be easy
so
7. rico average=15.5mph or 15.5/h
in 2.5 hours how far travel
15.5 in 1 hour
in 2 hours he will travel 2 times 15.5 miles
so in 2.5 hours he will travel 15.5 times 2.5 miles or 38.75
8. use estimation to show reasonable
15.5 can be rounded to 16
16 times 2 is 32
16 times 3 is 48
0.5 is half of 1 so the average is about the answer
(32+48)/2=80/2=40
he will travel about 40 miles (less since you rounded 15.5 up to 16)
so it is reasonable
