The answer is c
I love math btw
Y=3x+4.5 is NOT the equation the correct answer is what the person under me typed
Answer:
20
Step-by-step explanation:
To solve this you have to make a system of equations.
Since the father and son's age sum up to 60, the first equation will be:
f + s = 60
Secondly, since the father's age is 5 times the age of the son 6 years ago the equation will be:
6 - (5s) = f
Now, you have to solve the first equation to let it equal to s
f + s = 60
f = 60 - s
Plug in
6 - 5s = 60 - s
+s +s
6 - 4s = 60
-6 -6
---------------------
-4s = 54
----- -----
-4 -4
s ≅ 14
14 + 6 = 20
Answer:
Step-by-step explanation:
x = 8
y = 40
By 30%
original=100%
100%+30%=130%
find 130% of 288846
1.30 times 288846=375499.8
answer is C which is closest
