Eder earns $22 per hour, plus a daily allowance of $15. Briana earns $12 per hours, plus a daily lunch allowance of $25. Write an equation to show the number of hours each person must earn the same amount. Then solve for x, the number of hours.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
