almond37 [142]

Answer:

The 7.14% of her income is the income tax .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

A house painter has an annual income of $35,000 and paid $2,500 in income tax.

Here

Part value = $2500

Total value = $35000

Put in the formula

Percentage = \frac{2500\times 100}{35000}

Percentage = \frac{250000}{35000}

Percentage = 7.14\ (Approx)

Therefore the 7.14% of her income is the income tax .

 5/4=y−1/4<br><br>y=_____<br>What is the answer?
Nat2105 [25]

In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:


5/4 = y - 1/4


5/4 + 1/4 = y - 1/4 + 1/4


6/4 = y


y = 6/4


Don't forget to simplify y:


y = 3/2
