The answer is B.
Hope you have a good day.
In solving this type of problem always look for the person you don't have any information about in this case it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore
X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.
x+7+x+7.5-12+ x=63
3x+3=63
3x=60
x=20
Plug in the x for each person
therefore Eve=$20
Justin=$20+$7.50= $27.50
Emma has $12 less than Justin therefore $15.50
Add all the money and it equals $63
F(x) = 1.25(38 - x)
Finding the inverse of a function:
y = f(x)
y = 1.25(38 - x)
Solve for x:
y = 1.25(38 - x)
y/1.25 = 38-x
x = 38 - y/1.25
Switch x and y.
y = 38 - x/1.25
f^-1(x) = 38 - x/1.25
Answer:
p =43/2
Step-by-step explanation:
8/9 = 12/(p-8)
We can use cross products
8 * (p-8) = 9*12
Distribute
8p - 64 = 108
Add 64 to each side
8p -64+64 = 108+64
8p =172
Divide by 8
8p/8 =172 /8
p =43/2
