Azul bought 10 reams of paper at the store for a total of $84. the tax on the purchase was four dollars what was the cost of each ream of paper. which equation could be used to represent this situation

10x+4 = 84

Step-by-step explanation:

Azul bought 10 reams of paper at x dollars per ream

10x

The tax was 4 dollars

10x+4

The total cost was 84 dollars

10x+4 = 84

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
