How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)
lianna [129]

Answer:

The equation has only one solution which is:

  • x = 10

Step-by-step explanation:

Given the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

Let us solve the equation to determine the type of the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

subtract the number: -1 - 3 = -4

3x+6=4x-4

subtract 6 from both sides

3x+6-6=4x-4-6

3x=4x-10

subtract 4x from both sides

3x-4x=4x-10-4x

-x=-10

Divide both sides y -1

\frac{-x}{-1}=\frac{-10}{-1}

x=10

Therefore, the equation has only one solution which is:

  • x = 10

Andrew pays $15 for a haircut . He leaves a 20% tip. What is the total amount andrew pays for the haircut, including the tip?
beks73 [17]

Answer:

$18.00

Step-by-step explanation:

Start by working out 10%, that's easy:

15 ÷ 10 = 1.5

That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:

1.50 x 2 = 3

A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00
