You buy the same number of brushes, rollers and paint cans. Write an expression in simples form that represents the total amount
jeyben [28]
T= 21.79x + 3.99x + 6.89x where t is the total cost and x is the number of brushes/rollers/paint cans you buy. You don't need a different variable for each item because you buy the same amount of each.

Please help me solve this problem
Stells [14]

Answer:

$180

Step-by-step explanation:

To solve, we can set up a proportion and solve.

You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work

45/7.5=x/30

Cross multiply

45*30=7.5*x

1350=7.5x

To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5

1350/7.5=7.5x/7.5

180=x

So, for 30 hours of work, you would earn $180

NikAS [45]

Answer:

Step-by-step explanation:

The mean (or average) of a set of numbers can be found with the following formula:

Mean = \frac{A_{1} + A_{2} + ... + A_{N}}{N}

For this problem, we have five numbers, so we add them together and divide by 5:

Mean = \frac{92 + 85 + 78 + 97 + 88}{5}

Mean = \frac{440}{5}

Mean = 88
