W=normal hourly wage
4W-12.75+5*1.5W-8.50=70.75
4W-12.75+7.5W-8.50=70.75
11.5W-21.25=70.75
11.5W=92
W=8
Normal hourly rate is $8/hour
Check
32-12.75+60-8.50=70.75
Answer:
(C)90 – 10y = 5x
Step-by-step explanation:
Given:
x = number of times she hiked the 5-mile trail
- Then, total Distance covered on the 5-mile trail =5x
y = number of times she hiked the 10-mile trail
- Then, total Distance covered on the 10-mile trail =10y
Maria hikes a total of 90 miles
Therefore, total distance hiked can be represented by the equation:
5x+10y=90
Subtract 10y from both sides, we have:
5x=90-10y
This is option C.
The situation above is an arithmetic sequence with the third term (a3) equal to $285 and sixth term (a6) equal to $510. To determine the nth term of the arithmetic sequence, use the equation,
an = a1 + (n - 1)d
where a1 is the first term and d is the common difference. To solve for these, use the given values,
285 = a1 + (3-1)(d)
510 = a1 + (5 -1)(d)
Solving for the unknowns gives an answer of a1 = 60 and d = 112.5.Thus, the equation is,
y = 60 + 112.5x
Answer:
x= amount of times that these kids ride their bikes to school in a week
D = total distance
w = weeks
Step-by-step explanation:
The equation would be 0.05x + 3.15 = 5.10
0.05x = 1.95 (subtraction)
x = 39 (division)
