2x/5 - X/2 = 40
LCD = 10
2•(2x/5) - 5•(X/2) = 40
4x/10 - 5x/10 = 40
4x-5x/10 = 40
-X/10 = 40
10•(-X/10) = 40 • 10
-X = 400
-X/-1 = 400/-1
X = -400.
I believe the solution is that X = -400.
Answer:
The answer would be 19.25 ft because 1cm x 2.5 = 2.5 ft so you will have to do the same to 7.7 cm : 7.7cm x 2.5 = 19.25 ft.
Step-by-step explanation:
The function for this would be
f(x)= 70x + 5
Plug the 4 and half hours (4.5) into the function
f(x) = (70 x 4.5) + 5
You then get 315 from multiplying 70 and 4.5. Then add the additional 5 from gasoline.
You end up with 320$ for working 4 and a half hours
Answer:
C: (x + 4)(x - 1)
Step-by-step explanation:
Please use " ^ " to indicate exponentiation. Thanks.
x2 + 3x – 4 → x^2 + 3x - 4 = (x + 4)(x - 1) This matches Answer C.
