Answer:
x = 222
Step-by-step explanation:
8 = x% * 400
8 = x/100 * 400
8 = x * 4
4x = 8
Divide 4 on both sides.
x = 8/4
x = 2
2 percent<span> of 400 is 8.</span>
Answer:
The total number of members are 128 members
Step-by-step explanation:
From the question, mixing the ratio of children to adult, we have ;
7:9
There are 16 more adult members
So if there are x children, then there are 16 + x adults
Thus, the total number of members will be;
16 + x + x = 2x + 16
Now, we have that;
7/16 * (2x + 16) = x
7(2x + 16) = 16x
14x + 112 = 16x
16x-14x = 112
2x = 112
x = 112/2
x = 56
The total number of members is thus;
2(56) + 16 = 128
I hope this helps. sorry if it does not
Answer:
A
Step-by-step explanation:
You literally just have to use a calc or solve it by yourself. Doesn't need a graph.
-2x + 3 = 3x - 2 (-3 and -x create positive)
-5x + 3 = -2 (subtract 3x from both sides)
-5x = -5
x= 1
