The property taxes on a house were $1000. What was the tax rate if the house was valued at $125,000

The tax rate was 0.8%

Step-by-step explanation:

Set up an equation:

x = tax rate

1000/125000 = x/100

Cross multiply:

1000 × 100 = 125000 × x

100000 = 125000x

0.8 = x

Check your work:

1000/125000 = 0.8/100

0.008 = 0.008

Correct!

Another way to check your work:

1000 × 100 = 125000 × 0.8

100000 = 100000

Correct!

You have to plug in the numbers for x and y. So 3 the the power of 2 will turn into 3(2^2) and the y into 5. Which leaves your new equation

3(2^2)+5 which simplifies to 17.
