The time for the job for which the two company are the same is 16
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16

Step-by-step explanation:
Answer:
106°
Step-by-step explanation:
Given that the points B, C and D are colinear, it means that
2x + 40 = 5x + 10
collecting like terms
40 - 10 = 5x - 2x
3x = 30
x = 10
Hence the angle ∠E
= 5(10) + 10
= 60°
∠BCE = X + 4
= 10 + 4
= 14°
Given that the sum of angles in a triangle is 180°
∠D + 14 + 60 = 180
∠D = 180 - 74
= 106°
