Answer:
No
Step-by-step explanation:
Do the equations and keep the (x) unless it is by itself. If it is by itself it equals 1 then you continue with the problems.

15. Interpret
I'll try to explain this quick so you can sleep. Sleep is very important for brain activity and is very important to help us learn more efficiently and to help us feel more energized and healthy (and sleep is just amazing in general) :)
All of the numbers below 1000 are going to give us negative number answers. For all of them, we just subtract 1000 from it to see how much over or below we are.
February: 10
March: -5
April: 50
May: -25
June: -20

16. Analyze
An <u>integer </u>is just a number with no fraction or semi-value that is part of it. So 7 and -10 are integers while -1.5 and 2/3 are not.
A negative integer is one below zero, and a positive is one above zero.
PART A: Letters a and c represent the negative integers because they are to the left of zero on the number line.
PART B: letters b and d represent the positive integers because they are above zero on the number line.
PART C: They can be described as additive inverses, which have a different sign but the same <u>absolute value</u> (distance from zero). They are called this because when you combine them you get zero.

Enjoy your sleep and keep on learning! :D
5(v+2) = -2(7v-3) + 9
------------------------------------
Distribute:
5v + 10 = -14v + 6 + 9
Combine Like Terms
5v + 10 = (-14v+9v)+6
5v + 10 = -5v + 6
Subtract -5v from both sides
10v + 10 = 6
Subtract 10 from both sides
10v = -4
Reduce
5v = -2
Divide both sides by 5
v = -2/5
Simplify
v = -0.2
To solve this equation with algebra
4/7 = 1/x
(4/7)x = (1/x)x
4x/7 = 1
(4x/7)7 = 1(7)
4x = 7
4x/4 = 7/4
x = 1.75
1.75 yards of fabric are needed to make 1 dress.
Hope this helps! <3
