2 would be the answer. Replace the x with the three and multiply that with the 2 and then subtract 4.
Is there options? I don't think I can help if there isn't number options.
After 45....- 315. After 0 min 0. And finally, After 3 hrs, -2700
A + c = 3806....a = 3806 - c
19a + 9.5c = 55157
19(3806 - c) + 9.5c = 55157
72314 - 19c + 9.5c = 55157
-19c + 9.5c = 55157 - 72314
-9.5c = -17157
c = -17157/-9.5
c = 1806 <== # of children
and there were 2000 adults
8.
You get this by putting the 1 into the g function, then placing the result into the h function. This will give you 2 and then the final answer of 8.
