Answer:

Simplifying

3u = 72

Solving

3u = 72

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Divide each side by '3'.

u = 24

Simplifying

u = 24

During the summer, the height of the water in the pool decreased by 5 inches each week due to evaporation. What is the change in
rjkz [21]

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 y=-5x, since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know x=8, since we need to find the change for 8 weeks.

y = -5\cdot 8

-5 \cdot 8 = -40

y=-40

The change will be the absolute value of -40, which just makes it positive, so 40.

Hope this helped!

Elizabeth is a manager at a nursery and is in charge of displaying potted trees in a row Elizabeth has 150 citrus trees and 180
vampirchik [111]

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.

Solve 7x + 1 < 4(x - 2). {x | x < 3} {x | x > 3} {x | x > -3} {x | x < -3}
Luda [366]

Hello there!

Answer:

\boxed{D. x

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!

-Charlie

Have a nice day! :)
