Answer: 41
Step-by-step explanation:
The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

<u><em>The correct question is</em></u>
Mr. Hopkins is building a sandbox for his children. It would cost $228 for the sand if he builds a sandbox with dimensions 9 ft by 6 ft. If Mr. Hopkins decides to increase the size to 13 1/2 ft by 8 ft but keep the same depth of sand, how much would the sand cost
step 1
Find the unit rate of the cost per square foot
Divide the total cost by the area
step 2
Find the area of the increased sandbox
we have
The area is equal to
step 3
Find the cost of the new sandbox
Multiply the area by the cost per square foot
1) A, 1:2
Because the ratio of the points is 7:14
2) C, 3:5
Because there are 9:15 boys, so divide by 3
3) C, 33 yards
Convert 1200 inches into yards, it makes 33.3
