Leslie mows lawns to earn money. For each customer, she charges $2.00 for gas and $3.00 per 12 hour of work. Let x represent the

RUDIKE [14]

Answer:

See Explanation

Step-by-step explanation:

Given

$Gas = \$2.00$

$Rate = \$3.00/12hr$

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & { } & {B} & {4} & { } & {C} & {6} &{ } \ \end{array}$ ---- Missing table

Required

Complete the table and plot the graph

First, we determine the equation of the table:

$Gas = \$2.00$

$Rate = \$3.00/12hr$ implies that:

$Rate = \$0.25/hr$

So:

$y = Gas + Rate * x$

$y = 2+ 0.25* x$

$y = 2+ 0.25 x$

To complete the table, we have:

$x = 2$

$y = 2+ 0.25 x = 2+0.25 * 2 = 2.5$

$x = 4$

$y = 2+ 0.25 x = 2+0.25 * 4 = 3$

$x = 6$

$y = 2+ 0.25 x = 2+0.25 * 6 = 3.5$

So, the complete table is:

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & {2.5} & {B} & {4} & {3} & {C} & {6} &{3.5} \ \end{array}$

1. The product of five and a number is 15

dedylja [7]

Answer:

Step-by-step explanation:

(1) $5x = 15$

Dividing both sides by $5$ will give us the answer:

$x = 3$

(2) $x + 6 = 16$

Subtracting both sides by $6$ will give us the answer:

$x = 10$

(3) $\frac{27}{x} = 9$

First let's multiply both sides by $x$

$27 = 9x$

Now, let's divide both sides by $9$ to get our answer:

$x = 3$

(4) $6x = 72$

Dividing both sides by $6$ will give us the answer:

$x = 12$
