Answer:

It is because you have to get rid of the power of 2 from c. In order to get rid, you have to square root it on both sides :

c² = 74

√(c²) = √74

c^(1/2×2) = √74

c = √74

Using Indices formula, (a^m)^n = a^(mn)

What is 575% written as a mixed number?
pav-90 [236]

<u><em>Answer:</em></u>

575% as a mixed number is 5\frac{3}{4}

<u><em>Explanation:</em></u>

575% is equivalent to \frac{575}{100} which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as \frac{75}{100}. This value can be simplified by dividing both the numerator and the denominator by 25. This would give us \frac{3}{4}

<u>Back to our number:</u>

5.75 = 5 + 0.75 = 5 + \frac{75}{100} = 5 + \frac{3}{4} = 5\frac{3}{4}

Hope this helps :)

On Sunday, a local hamburger shop sold a combined of 572 hamburger and cheeseburger. The number of cheeseburgers sold was three
igor_vitrenko [27]
Answer: 143 hamburgers and 429 cheese burgers

Explanation:

Call h and c the number of both items.
(h-hamburger and c-cheeseburger)

h + c = 572
c = 3h

Sub the second into the first

h + 3h = 572
4h = 572

Divide both sides by 4
h = 143 hamburgers

Use this back into the second equation
c = 3 • 143 = 429 cheeseburgers
