The expression is 5x - 2y
Use PEMDAS and work out the rest
x = 3 and y = 4
5 x = 5 x 3 = 15
2 y = 2 x 4 = 8
15( x ) - 8 (y) = 7
The answer is 7
Hope This Helps You!
Good Luck Studying :)
Answer:
70.0000000001 meters per second
Step-by-step explanation:
The formula is to multiply by the factor 0.27777777777817.
252 km/h * 0.27777777777817 = 70.0000000001

Answer:
(A) $260 + $57x = $488
(B) 4 hours
Step-by-step explanation:
(A) We need to find out how many hours of labor he needed to complete the job. That's what the x will represent.
We know that he charged Katy for the parts and for the labor, with an hourly rate of $57.
We need to sum the amount of money he charged for the parts with the hourly rate multiplied by the number of hours he worked.
Let's notice that we multiply the number of hours just to the hourly rate, the price of the parts doesn't depend on how many hours he worked.
That is $260 + $57*x
We know that the total was $488, so we just need to equal the expression before to the total.
$260 + $57x = $488
That's the expression we were looking for.
(B) Let's solve the equation. We need to leave the x alone on one side of the equation.
First, let's subtract $260 on both sides:
$260 + $57x - $260 = $488 - $260
$57x = $228
Now we divide by $57 on both sides:
$57x/$57 = $228/$57
x = 4
He needed 4 hours to do the job.
