Vanessa practices the piano for 60 minutes each day. so far, she has practiced 42 minutes today. what percent of her practice time does she have left to complete?

30%

Step-by-step explanation:

1) Find the amount of time left to complete

60 minutes total - 42 minutes already played = 18 minutes left

2) Divide the amount of minutes left by the total minutes

18 minutes left ÷ 60 minutes total = 0.3

3) Multiply that value by 100 to turn the decimal into a percent

0.3 * 100 = 30%

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
