Find the length of EF

9

Step-by-step explanation:

1. First, we need to set up an equation to find the value of x and then the length of EF.

2. We know that DG is equal to 33, so we can add all the three sections it's cut into altogether to get 33. Therefore, we get an equation of:

3. (Solving for x)

Step 1: Simplify both sides of the equation.

Step 2: Add 58 to both sides.

Step 3: Divide both sides by 7.

4. Now that we know x is equal to 13, we can plug that value in for the expression 3x - 30.

Therefore, the length of EF is 9.

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
