Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.
Answers
Answer:
Inequality: .80x +21 ≤ 82
Answer: 76.25 miles in total
Step-by-step explanation:
Hi,
An inequality to represent this is .80x +21 ≤ 82
(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).
Now we solve...
.80x + 21 ≤ 82
Subtract 21 on both sides...
.80x ≤ 61
Now, divide by .80 on both sides...
x ≤ 76.25
He can drive up to 76.25 miles in total
Hope this helps :)

3(y+25)=−15
what is y
Answers
Answer:
y = -30
Step-by-step explanation:
3(y+25)=−15
3y +75 = -15
subtract 75 from each side of the equation:
3y = -90
y = -90/3 = -30
proof:
substituting -30 for y:
3(-30 + 25) = -15
-90 + 75 = -15
-15 = -15
Answer: The answer to your question is y= -30

Answer:
answer of q no.2
-3 and 12
Explanation:Suppose two numbers are x and y
smaller number = x
larger number = y
Given that,
The difference of two numbers is 15
Equation 1
y - x = 15
Five times the smaller is the same as 9 less than twice the larger.
Equation 2
5x = 9 - 2y
Solve them
-x = 15 - y
x = y -15
put value of x in equation 2
5(y - 15) = 9 - 2y
-75 + 5y = 9 - 2y
-75 - 9 = -2y - 5y
-84 = -7y
y = 84/7
y = 12
x = 12 - 15
x = -3

Chloe is drinking 3/5 cup of water every 6 minutes. How many cups will they drink in 2 hours?
Answers
Answer:
12 cups
Step-by-step explanation:
One of the easiest ways to solve this problem is to first turn the fraction into a decimal. 3/5=0.6
The second step is to see how much water Chloe drinks in an hour. Since there are 60 minutes in an hour and 6 times 10 is 60, we do 0.6 times 10 to see how much water Chloe drinks in one hour. 0.6x10=6
The third and final step is to double 6. We do this because 6 is how many cups of water Chloe drinks in one hour, but we need to find two. 6x2=12.
Therefore, Chloe would drink 12 cups of water in 2 hours.
Answer:
Step-by-step explanation:
12 cups. You have to divide 120 by 6, then you divide that answer (20) by 3/5, which is 0.6 in decimal form, your answer should be 12 cups of water.
