Given:
Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.
Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.
To find:
The number of months after which the costs for the girls’ cell phone plans the same.
Solution:
Let x be the number of months.
Total cost = Fixed cost + Variable cost
According to the question, cost equation for Anna’s cell phone is
...(i)
Cost equation for Evelyn's cell phone is
...(ii)
Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.
Divide both sides by 10.
Therefore, the costs for the girls’ cell phone plans the same after 10 months.
Answer: 5
0 Remainder
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 8 on the left side and the dividend 40 on the right side like this:
8 ⟌ 4 0
Step 2:
The divisor (8) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
8 ⟌ 4 0
Step 3:
Multiply the divisor by the result in the previous step (8 x 0 = 0) and write that answer below the dividend.
0
8 ⟌ 4 0
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
8 ⟌ 4 0
- 0
4
Step 5:
Move down the 2nd digit of the dividend (0) like this:
0
8 ⟌ 4 0
- 0
4 0
Step 6:
The divisor (8) goes into the bottom number (40), 5 time(s). Therefore, put 5 on top:
0 5
8 ⟌ 4 0
- 0
4 0
Step 7:
Multiply the divisor by the result in the previous step (8 x 5 = 40) and write that answer at the bottom:
0 5
8 ⟌ 4 0
- 0
4 0
4 0
Step 8:
Subtract the result in the previous step from the number written above it. (40 - 40 = 0) and write the answer at the bottom.
0 5
8 ⟌ 4 0
- 0
4 0
- 4 0
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 40 divided by 8 calculated using Long Division is:
5
0 Remainder
Answer:
parallel lines has same slope
we have
y = -3/2x+2
comparing with y = mx+c
m=-3/2
so answer is -3/2
The answer is 310. You subtract 72 from 382 and you get your answer of 310.
Answer:
Y is 5
