Answer:

The number was 2

Step-by-step explanation:

To solve this you would just have to work backwards using the inverses of operations previously used

First you would subtract 11 from 12:

12-11=1

Then you would multiply by 2:

1 x 2=2

Jebb is the tallest player on his basketball team. He is 1 1/2 times as tall as the shortest girl in sixth grade, who is 4 1/4 f
skelet666 [1.2K]

Answer:

51/8 or 6 3/8 (depending on if you need to simplify or not)

 Step-by-step explanation:

Since the girl is 4.25 feet tall, you would multiply that by 1.5 which would get you 6.375 then, you convert to a fraction. The fraction would be 51/8 which would be equivalent to 6 3/8. So, Jebb is 6 3/8 feet tall.


Hope this helped! :)

Solve the equation.<br><br> 5x + 6 = 2(2x – 3)<br><br> what dose x =
Lady_Fox [76]

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+6=2(2x−3)

Step 1: Simplify both sides of the equation.

5x+6=2(2x−3)

5x+6=(2)(2x)+(2)(−3)(Distribute)

5x+6=4x+−6

5x+6=4x−6

Step 2: Subtract 4x from both sides.

5x+6−4x=4x−6−4x

x+6=−6

Step 3: Subtract 6 from both sides.

x+6−6=−6−6
