Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
Answer:
3.50+0.125m(0.23) = C
Step-by-step explanation:
Initial fee- $3.50
Each 1/8 mile costs $0.23
total cost = C
1/8 = 0.125
3.50+0.125m(0.23) = C
Answer:
5
Step-by-step explanation:
<u>move constant</u>
x+7 ≥ 12
<u>subtract</u>
x≥ 12-7
<u>solution</u>
x ≥ 5
Where R is the median between Q and L:
From my understanding of a triangle's centroid, it divides an angle bisector into parts of 2/3 and 1/3. In the given problem, these divisions are NS and SR. Therefore, twice SR would be equal to NS. From here, we can get the value of X, to solve for SR.
NS = 2SR
(x + 10) = 2(x + 3)
x + 10 = 2x + 6
x = 4
Therefore, SR = (x + 3) = 7
I'm gonna say A. It makes the most sense to me.
