Find the value of x.
agasfer [191]

Answer:

\boxed {\boxed {\sf A. \ 18}}

Step-by-step explanation:

The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.

Therefore, the sum of the angle measures must equal 90. We can set up an equation.

56+(x+16)=90

Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.

(56+16)+x=90\\

72+x=90

Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.

72-72+x=90-72

x=18

x is equal to 18 and choice A is correct.

35x - 35x + 21x - 21

nadya68 [22]

Answer: The total profit is $129

Step-by-step explanation:

The total revenue, was $147 (the total they earned), and the cost of the materials is $18 (how much they returned for the materials)

The total profit is computed as the difference between the revenue and the costs, then the total profit of the kids in this case is:

Profit = $147 - $18 = $129

This means that Tia and Jaden earned $129, if they divide it evenly, each one of them gets $129/2 = $64.5
