The best choice would probaly be b but im not positive
if its not b then its a
Alright, so the answer for:
3) is 3v + 4
Answer:
9
Step-by-step explanation:
Use PEMDAS to solve it.
2 3 - (8-4) + 5 =
First: 2 3 - (4) + 5 =
Second: solve the 2 to the power of 3 exponent
2×2×2=8 (2×2=4 then 4×2=8)
So, 8 - 4 + 5 =
Third: 4 + 5 =
Last: 9
Answer:
the answer is B, because x+x+x is equal to 3×x which is 3x
Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
