F(x)=60+0,75x

Because she charges 60 per session, which will not change. And you don’t know how many miles she has to drive so that will be 0,75x.

Answer:

Step-by-step explanation:

Charge(x) = $60 + ($0.75/mile)x, where x is the number of miles driven.

That $60 is the y-intercept and represents the (flat) charge per session. The ($0.75/mile)x represents the amount charged for the total number of miles driven.

One number was divided by 2, followed by this quotient being multiplied by 4. next, the product was added to 9. the total sum wa

grin007 [14]

Answer:

Step-by-step explanation:

First, turn the word problem into an equation:

n(a number) was divided by 2

$\frac{n}{2}$

followed by this quotient beying multiplied by 4

$\frac{n}{2}$ *4

the product was added to 9

$\frac{n}{2}$ *4+9

the total sum was 25

$\frac{n}{2}$ *4+9 = 25

use PEMDAS to solve the equation

subtract 9 on both sides

$\frac{n}{2}$ *4 = 16

cancel the 2 and the 4 using factorization

n*2 = 16

divide 2 on both sides

n = 8

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.
