$8.00
Step-by-step explanation:
Let's set up the equation first.
What do we know:
1. We have 6 friends spliting the costs of the gifts
2. After purchasing the gifts they have $42 in change
3. They originally had $90 to spend.
Equation:
6f + $42 = $90
Next: Subtract the $42 from each side and we are left with:
6f = $48
Divide both sides by 6 and we are left with
f = $8
Since f represented the cost each friend spent our answer is $8.00

Answer: stop pay attention in class
Step-by-step explanation:
6x - 7 = 19
<span>6x = 19 + 7 </span>
<span>6x = 26 (divide both sides by 6 to get x) </span>
<span>6x/6 = 26/6 </span>
<span>x = 4.33333333333 </span>
