Answer:
A) 40 + d
B) 45 days
Step-by-step explanation:
A)
total cost = (cost of the air conditioner itself) + (money charged per day)*(days)
cost of air conditioner itself = $40
money charged per day = $1
days = d
40 + 1*d
= 40 + d
B)
total cost = 40 + d
total cost = $85
85 = 40 + d
45 = d
Time used the air conditioner for 45 days.

D (6,5)
Answers
Answer:
This would be D. (6, 5)
Step-by-step explanation:
When moving 9 to the right, you take -3 and add 9 to it, which gives you 6.
Do the same thing with 15, but subtract 10 from it, since you are going to the left. This gives you 5.
Therefore, your answer should be (6, 5)
-3 + 9 = 6
15 + 10 = 5

Answer:
the teacher bought 100 balloons, and 95 of them were left for the party.
Step-by-step explanation:
red balloons is given, 40.
first you find the green balloons.
the number of green balloons is 3/5 the number of red balloons.
3/5 * 40 = 24
so there are 24 green balloons.
next is yellow balloons.
the number of green balloons is 2/3 the number of yellow balloons.
24 = 2/3 * x
24 ÷ 2/3 = x
24 ÷ 2/3 = 36
there are 36 yellow balloons.
find the total balloons:
40 + 24 + 36 = 100
the teacher bought 100 balloons.
1/20 of the red balloons popped.
1/20 * 40 = 2
2 of the red balloons popped
1/12 of the green balloons popped
1/12 * 24 = 2
2 of the green balloons popped.
1/36 of the yellow balloons popped
1/36 * 36 = 1
1 yellow balloon popped
2 + 2 + 1 = 5
100 - 5 = 95
there were 95 balloons left for the party.
