Step-by-step explanation:
I think you are trying to find x, I dunno, but if you are here's the solution.
when trying to find x, your main goal is to shift all x terms to one side.
For the first one
4x-3 = 5x-3
Carry all x terms to one side:
(4x-3)-5x = (5x-3)-5x
4x-5x-3 = -3
Shift all constants (purely just numbers, no x) to the other side
(4x-5x-3)+3 = (-3)+3
4x-5x = 0
-x = 0
x = 0
The second one:
-2x = 3x-5
5x = -5
x = -1
Done, have fun with math!
I think it is 88 not sure though
Answer:
8/27 cups
Step-by-step explanation:
Nima uses 2/3 cups of peanuts to make a recipe of 2 1/4 = 9/4 cups of trail mix. If we want to find how many cups of peanuts are there per cup of trail mix, we can do a rule of three:
If 9/4 cups of trail mix need 2/3 cups of peanuts, 1 cup of trail mix need X cups of peanuts:
9/4 cups of trail mix -> 2/3 cups of peanuts
1 cup of trail mix -> X cups of peanuts
9/4 / 1 = 2/3 / X
9/4 = 2/(3*X)
3*X*9 = 4*2
27*X = 8
X = 8/27 cups
The answer would be f(x)= x+47
