-2(p - 1) = 15


-2p + 2 = 15

-2p = 13


Divide by -2 on both sides.

Joe made a scale drawing of the community pool in his town.
Effectus [21]

Answer:

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

Step-by-step explanation:

In the scale drawing of Joe, the community pool has (length : width) = 8 : 3  

Let the actual length of the pool is 8x meters and the actual width is 3x meters.  

Now, given that the actual pool has a perimeter of 77 meters.  

So, 2(8x + 3x) = 77  

⇒ 22x = 77  

⇒ x = 3.5  

So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)

Breann solved the system of equations below. What mistake did she make in her work?
mihalych1998 [28]
If 2x+y=5, then y=5-2x, so she substituted correctly.
x+4x=5x, so she combined like terms correctly.
She didn't subtract 10 from both sides, she added 10 to both sides.

Check the solution:
2x+y=5 \hbox{ and } x-2y=10 \\
2 \times 4-3=5 \hbox{ and } 4-2 \times (-3)=10 \\
8-3=5 \hbox{ and } 4+6=10 \\
5=5 \hbox{ and } 10=10 \\
\checkmark

The answer is: She made no mistake.
