Answer:
3 miles per min
Step-by-step explanation:
3 miles x 15 (min) = 45 mph
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.
24=(n-3)(2)
24\2=(n-3)(2)/2 divide by two on both sides
12=n-3
12+3=n-3+3 add three on both sides to isolate the variable
15=n
Then check the work
24=(15-3)(2)
24=12(2)
24=24

Answer:
Answer is 261
Step-by-step explanation:
-4r+5y-14 r=0 y=55
insert "r" and "y" values into equation
=-4(0)+5(55)-14
evaluate;
-4(0)=0
5(55)=275
so, now the equation would look like this;
=275-14
<h2>=261</h2>
