Answer: D) 3x - 5
Step-by-step explanation:
f(x) - g(x)
f(x) = 1/2x - 3
g(x) = -5/2x + 2
Using the values of f(x) and g(x) gives us the equation:
1/2x - 3 - (-5/2x +2)
By distributing the negative sign, the signs on 5/2 and 2 are flipped, making them positive and negative respectively.
Our new equation is:
1/2x -3 + 5/2x -2
Adding up like numbers gives us:
6/2x - 5
Simplifying 6/2x => 3x
So our final equation is:
3x - 5
Hope this helps!
Answer:
14.26
Step-by-step explanation:
7/3 x 5/3 x 11/3 = 7(5)11/(3³)
35 x 11 = 385/27
385 / 27 = 14.26
J=john
m=mary
j is 2 times as old as mary
j=2 times m
sum is 21
m+j=21
find mary
subsitute
j=2m therefor subsitute 2m for j
m+2m=21
add like terms
3m=21
divide by 3
m=7
mary=7
