<span><u><em>9.24 is 24% of 38.5</em></u>
</span>100%=38.5
x%=9.24
100%/x%=38.5/9.24
(100/x)*x=(38.5/9.24)*x
100=4.16666666667*x
y (4.16666666667) to get x
100/4.16666666667=x
24=x
x=24
Answer:
3w+7
c^2 + 4c - 3
Step-by-step explanation:
8v+w+7-8v+2w
8v-8v +w+2w +7
0+3w+7
3w+7
4c^2+6c-3c^2-2c-3
4c^2-3c^2 + 6c-2c -3
c^2+4c-3
By using the exact same method I provided on your last question we get..
1.
2.
The right equations are a+c=30 (total number of people) and 8a+c=100 (total amount of money). So answers B and D cannot be right.
a+c=30 can be rewritten as c=30-a and filled into the second one:
8a + 30-a = 100 => 7a = 70 => a=10
That leaves answer A as the right one.
