Step-by-step explanation:
The amount of times you roll the dice x 10 = answer
So simplify the equation
remember
add like terms
x+x=2x
1+1=2
2x+4x=6x
3x^2+3x^2=6x^2
cannnot add x and x^2
so grou plike terms
-5x-3x+1x+4-1-9
add
-5-3+1=-7 and 4-1-9=-6 so
-7x-6 is the answer
ax+b
-7x-6
a=-7
b=-6
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.
