ANSWER: x=5/3, -1. Good luck. Hope this suffices.

Explanation for x=-1: |9x-3|=12. Lets take the absolute value brackets away for a sec. Add 3 to both sides 9x-3+3=-12+3, simplify: 9x=-9, divide both sides by nine:9x/9=-9/9. And that means that x=-1.

Explanation for x=5/3: |9x-3|=12. Add 3. 9x-3+3=12+3. Simplify: 9x=15. Divide both sides by 9. 9x/9=15/9. Simplify: x=5/3

Marcy has 150 to buy packages of hotdogs and hamburgers for her booth at the carnival. Grocery store she found packages of hotdo

bekas [8.4K]

Answer:

Part (A): The required equation will be: $6d+20b=150$

Part (B):The required equation will be: $d=\frac{150-20b}{6}$

Part (C):The required equation will be: $b=\frac{150-6d}{20}$

Step-by-step explanation:

Consider the provided information.

Let d represents number of packages of hot dogs and b represents the number of packages of hamburgers.

Part (a)

It is given that the cost of a package of hot dogs is $6 and cost of a package of hamburger is $20.

The required equation will be: $6d+20b=150$

Part (b) Solve the above equation for d.

Subtract 20b from both sides.

$6d=150-20b$

Divide 6 from both sides.

$d=\frac{150-20b}{6}$

The required equation will be: $d=\frac{150-20b}{6}$

Part (c) Solve the equation for b.

Subtract 6d from both sides.

$20b=150-6d$

Divide 20 from both sides, we get

$b=\frac{150-6d}{20}$

The required equation will be: $b=\frac{150-6d}{20}$
