in this problem we have
substitute in the formula above
Answer:
26
Step-by-step explanation:
do the math
Let the initial money be x so by question,
3x/5 +1x/5+1200=x
or, 1200= x - 4x/5
or, 1200 = 1x/5
or, 6000= x
hence the initial money was 6000$
Answer:
Zachary is 9, Nicole is 8, and Jaycob is 27.
Step-by-step explanation:
x=Zachary
y=Nicole
z=Jaycob
x+y+z=44
x*3=z
x-1=y
However, for now, let's just assume that x and y are actually the same, and that the answer is actually 45.
so, x*3=z, and y*3 also equals z.
This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.
A function whose values are found from two given functions by applying one function to an independent variable and then applying the second function to the result and whose domain consists of those values of the independent variable for which the result yielded by the first function lies in the domain of the second.
