Answer:

<h3>\boxed{ \mathsf{ \bold{ \purple{ 4x - 9}}}}</h3>

Step-by-step explanation:

\mathsf{5(2x - 1) - 2(3x + 2)}

Distribute 5 through the parentheses

\mathsf{10x - 5 - 2(3x + 2)}

Distribute 2 through the parentheses

\mathsf{10x - 5 -  6x - 4}

Collect like terms

\mathsf{4x - 5 - 4}

Calculate

\mathsf{4x - 9}

Hope I helped!

Best regards!

Dominic works on the weekends and on vacations from school mowing lawns in his neighborhood. For every lawn he mows, he charges
Ivahew [28]

Answer:

20\ lawns = \$240

9 \ lawns = \$108

<em>See Attachment for Graph</em>

<em></em>

Step-by-step explanation:

Given

1\ lawn = \$12

Solving (a): Number of lawns in $240

1\ lawn = \$12

Multiply both sides by 20

20 * 1\ lawn = \$12 * 20

20\ lawns = \$240

Solving (b): Cost of mowing 9 lawns

1\ lawn = \$12

Multiply both sides by 9

9 * 1\ lawn = \$12 * 9

9 \ lawns = \$108

To create a graph, we need to generate a formula;

If

1\ lawn = \$12

2\ lawn = \$24

3\ lawns = \$36

x\ lawns = \$12x

So:

<em>The graph formula is</em>

y = 12x

PROOF 252=11*22+10=242+10=252
