Answer:
40 inches
Step-by-step explanation:
We know that the height of water in a pool decreased 5 inches per week.
This means that we can form the equation
, since the amount of water remaining is proportionate to the amount of weeks that have passed.
We know
, since we need to find the change for 8 weeks.



The change will be the absolute value of -40, which just makes it positive, so 40.
Hope this helped!
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
Answer: the greatest number of trees that ElizaBeth can have in a row is 30
Step-by-step explanation:
given data:
citrus trees = 150
palm trees = 180
As we have to find the greatest number of trees that Elizabeth can have in a row, we will find the GCF or greatest common factor.
150 = 2 x 3 x 5 x 5
180 = 2 x 2 x 3 x 3 x 5
Greatest common factor is = 2 x 3 x 5 = 30
Therefore, the largest number of trees that ElizaBeth can have in a row is 30.
Hello there!
Answer:

Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, you expand.
4(x-2)=4x-8
7x+1<4x-8
Subtract by 1 both sides of an equation.
7x+1-1<4x-8-1
Add/Subtract numbers from left/right.
8+1=9
7x<4x-9
Then, you subtract by 4x both sides of an equation.
7x-4x<4x-9-4x
Simplify equation.
3x<-9
Divide by 3 both sides of an equation.
3x/3<-9/3
Divide numbers from left/right.
-9/3=-3
<u><em>x<-3 is the final answer.</em></u>
Hope this helps!
Thanks!
