10. This is because 3 evenly goes into 30 without a remaining fraction
5(2x - 4) = 45
10x - 20 = 45
10x = 45 + 20
10x = 65
x = 65/10 reduces to 13/2 or 6 1/2
Hello!
to find the percent of a whole, use this equation here:
(remaining) / (total) = X
X * 100 = %
in this case:
12 / 15 = 0.8
0.8 * 100 = 80
your answer is 80%
I hope this helps, and have a nice day!
10.20 x 9 = 91.8
( It's William and nine/eight friends, since they're dividing it among ALL people we count William in. )
A: William and nine friends <span>divided the bill evenly. If each person paid $10.20, what was the total bill?
</span>
10.20 x 10 = 102
B: <span>At a restaurant, William and eight friends divided the bill evenly. If each person paid $10.20, what was the total bill?
10.20 x 9 = 91.8
C: </span><span>At a restaurant, William and nine friends divided the bill evenly. If the total bill was $91.80, what did each person pay?
91.80 x 10 = 918
D: </span><span>At a restaurant, William and eight friends divided the bill evenly. If the total bill was $91.80, what did each person pay?
</span>91.80 x 9 = 826.2
So, your answer is B
