P − 10p + -5p + 14p − -9p − 2 = -20
djverab [1.8K]

You will need to work left to right.

p - 10p + -5p +14p - -9p - 2 = -20

-9p + -5p +14p - -9p - 2 = -20

-14p +14p - -9p - 2 = -20

0p- -9p - 2 = -20

9p - 2 = -20

Then you will want to eliminate 2 by adding it to both sides

9p = -18

Then divide by 9 to isolate P

p=-2

When is the constant of proportionality the same as the unit rate when comparing two quantities?
Leto [7]

Answer:

Given a table, we can always simplify each ratio pair to find the unit rate. When the unit rate remains the same it is called the constant of proportionality, 'k'. Multiply or divide by the constant of proportionality, to solve problems depending upon the information you're given.

Anestetic [448]

Answer:

a) 4 months

b) $600

Step-by-step explanation:

1. x - number of months the total amount paid to be the same for both stores.

2. That same amount for store A: 300 + 75 \times x

3. That same amount for store B: 200 + 100 \times x

4. Since it's the same amount for both stores we can make an equation:

  • 300+75\times x=200+100\times x
  • 300-200=100x-75x
  • 100=25x
  • x=4

5. To find that same amount, we can use either side of above equation:

  • 300+75\times 4=600
