A car wash charges a flat rate for the first 8 minutes of washing time and also charges a certain amount for each additional minute of washing time. Gina took 12 minutes to wash her car and it cost her a total of $5.00. Kris took 17 minutes to wash his truck at a total cost of $6.25.How much is the is the flat rate for the first 8 minutes? show equation to find answer. Plz answer this word problem.
Answers
flat rate = x
so for the first eight minutes they both have the same rate so this is also true Gina took 4 minutes to wash her car and it cost her a total of $5-x Kris took 9 minutes to wash his truck and it cost him a total of $6.25-x so for overtime 4mins=5-x, 9mins=6.25-x 4 times 9 = 36 so 36 mins = (45-9x)=(25-4x) so 45-9x=25-4x subtract 25 from both sides and get 20-9x= -4x subtract add 4x to both sides 20-5x=0 factor out the five 5(4-x)=0 (4-x) must =0 4-x=0 add x to both sides 4=x it cost $4 for flat rate
The gas tank of your car is 40% full. There are 8 gallons of gas in the tank. What is the capacity of the gas tank?
Answers
Percentage by which the gas tank of the car is full = 40% Amount of gas in the gas tank = 8 gallons Let us assume the capacity of the gas tank = x gallons Then 40% * x = 8 (40/100) * x = 8 4x/10 = 8 4x = 8 * 10 4x = 80 x = 80/4 = 20 gallons So the total capacity of the gas tank of the car is 20 gallons. I hope the procedure is clear to you.
Answer:
20 gallons
Step-by-step explanation:
40/100 = 8/x
40x=800
x=20 gallons
3z+4+5z-9 Simply the expression
Answers
You would simply combine like terms 3z+4+5z-9 3z+5z=8z 4-9=-5 Put them together to get a final answer of: 8z-5 OR -5+8x also works :)
Combine like terms to simplify.
3z + 5z = 8z
4 - 9 = -5
8z - 5
Answer: 8z - 5
To increase and amount by 17.5 which single multiplier would you use?
Answers
I suppose that the question is 17.5 %.
To increase an amount by a percentage, the multiplier is given by (100 + %)/100
Therefore, to increase an amount by 17.5%, the single multiplier is given by (100 + 17.5)/100 = 117.5/100 = 1.175
