Answer:

w = -z(-w) + 3(-w)

Step-by-step explanation:

z = w + 3 | Given

-w + z = 3 | Subtract w from both sides.

-w = -z + 3 | Subtract z from both sides

w = -z(-w) + 3(-w) | Multiply -w on both sides.

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}
