blondinia [14]

Answer:

y-x

Step-by-step explanation:

I assumed you meant that you wanted me to rewrite the expression without the absolute value signs. Since the absolute value of a number will be the same whichever way you place the numbers, you can rewrite |x-y| as y-x, as x is less than y.

Isaiah earns $60 per week mowing lawns in the summer and shoveling driveways in the winter. He invested $220 in equipment. How l

marysya [2.9K]

Answer:

18 weeks

Step-by-step explanation:

Create an equation where x is the number of weeks he works

60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.

Set this equal to 860, then solve for x, to find when he will earn $860

60x - 220 = 860

60x = 1080

x = 18

So, it will take him 18 weeks to earn $860

The coefficient of the variable is 3/8.

$\sf\dfrac{3}{8}(?+?)$

Divide 3/8 to each term to find out what goes in the parenthesis:

$\sf\dfrac{3}{8}b\div\dfrac{3}{8}=b$

So 'b' goes into the first spot in the parenthesis:

$\sf\dfrac{3}{8}(b+?)$

$\sf\dfrac{3}{4}\div\dfrac{3}{8}$

When dividing by fractions we flip(reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{3}$

Multiply:

$\sf\dfrac{24}{12}$

Divide:

$\sf 2$

This goes into the second spot in our parenthesis.

$\boxed{\sf\dfrac{3}{8}(b+2)}$
