What is the distance around a triangle that has sides measuring 21/8 feet, 31/2 feet and 21/2 feet?

Add all of the sides together. Make sure to use a common denominator because you are adding fractions. Don't forget your unit label (feet)
$\frac{21}{8}$ + $\frac{31}{2}$ + $\frac{21}{2}$
$\frac{21}{8}$ + $\frac{124}{8}$ + $\frac{84}{8}$
$\frac{229}{8}$ feet

A is false because this graph doesn't have any relative minimums because it never increases

B is false because this graph never increases

C is true

D is true because the graph never goes below 3, but it's blurry so I might be wrong

E is true because it never stops decreasing and has a domain of all real numbers

You have to subtract 12 from 50 to get 38 and multiply it by 12 (number of months) to get 456 eggs

How many hours did Diana work of she was paid $45.50

JulijaS [17]

I think it would be C because the equation is y=7x. y=7x is also equal to x=1/7y. If y=45.50, then you would have to divide y by 7, which would equal 6.5.
