How many solutions does the following equation have?<br> |3x + 12| = 18 (5 points)
DedPeter [7]

Answer: 2 solutions.

The given equation breaks down into these two equations

3x+12 = 18 and 3x+12 = -18

Basically 3x+12 equal to plus 18 and minus 18. This is due to the fact that something like |x| = 7 means x = 7 or x = -7, ie those x values are exactly seven units away from zero on the number line.

If you want to solve each equation, then

3x+12 = 18

3x = 18-12

3x = 6

x = 6/3

x = 2 is one solution

and

3x+12 = -18

3x = -18-12

3x = -30

x = -30/3

x = -10 is the other solution

A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would c
worty [1.4K]

Answer:

Option D is correct.

$408.04 the gas would cost for this car to travel 2,727 typical miles

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1 such as 3 miles per second or 4 kilometer per hour

As per the statement:

A car averages 27 miles per gallon.

⇒\text{Unit rate per gallon} = 27 miles

Total distance of car travel typical miles = 2727 miles.

\text{Number of gallons}=\frac{\text{Total distance}}{\text{Unit rate per gallon}}

Substitute the given values we have;

\text{Number of gallons} = \frac{2727}{27} = 101

It is also given that if gas costs $4.04 per gallon.

then;

In 1 gallon of gas = $4.04

then;

in 101 gallons of gas = 101 \cdot 4.04 = \$408.04

Therefore, $408.04 the gas would cost for this car to travel 2,727 typical miles
