Answer: 3 3/4
Step-by-step explanation:
From the question, we are informed that Jerome use 3 1/4 gallons of gasoline while driving from school to his baseball game.
Assuming that he originally had 7 gallons in his car, the amount of gasoline he have left will be:
= 7 - 3 1/4
= 3 3/4 gallons
First, isolate y in 7x-y=29 because 1 is y's coefficient.
7x-y=29
-y=29-7x
y=7x-29
Now, substitute 7x-29 for y in 7x+8y=20.
7x+8y=20
7x+8(7x-29)=20
7x+56x-232=20
Add all coefficients.
63x-232=20
Isolate x by adding 232 to both sides.
63x-232=20
63x=252
x=4
Now, substitute 4 for x in your first equation.
y=7x-29
y=7(4)-29
y=28-29
y=-1
Your answer would be (4,-1).

For a given input value n, the function g outputs a value m to satisfy the following equation.
3m-5n=11
Write a formula for g(n), in terms of n.
g(n)=
Answer:
3m-5n=11
the function g outputs a value m. It means we need to solve for m in terms of n
solve the given equation for m
3m-5n=11
Inverse of -5n is +5n so we add 5n on both sides
3m-5n + 5n=11
+ 5n
3m = 11 + 5n
Divide by 3 on both sides
m = 
The function g outputs the value m
So g(n) =
