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

The car was towed for 48 miles.

Step-by-step explanation:

Given,

Amount charges by Acme towing = $30

Per mile charges = $3

Total charged = $174

Let, x be the number of miles.

Towing charges + Per mile charges*number of miles = Total charged

30+3x=174

Subtracting 30 from both sides

$30-30+3x=174-30\\3x=144$

Dividing both sides by 3

$\frac{3x}{3}=\frac{144}{3}\\x=48$

The car was towed for 48 miles.

I NEED AN ANSWER PLEASE :(((

Answer:

80 lemons

Step-by-step explanation:

Let x represent the amount of lemons that were on the tree.

We can use this to set up an equation:

$40\%x=32$

Note that percentages can also be written as that number over 100.

$\frac{40}{100}x=32$

Simplify the fraction.

$\frac{2}{5}x=32$

Multiply both sides by 5

$2x=160$

Divide both sides by 2

$x=80$

There were 80 lemons on the tree before he picked the lemons.
