Step-by-step explanation:
your don't see what went wrong ?
Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3
Answer:
75%
Step-by-step explanation:
There is 1 whisker and quartiles 1-3 so:
25%+25%+25%=75%
Okay, so this is just a bunch of random information that's eying to trick you. The answer is in the question. "the telephone pole to a point on the ground 40 feet from its base."
Hope this helps! f-1(x)=x/2-1/2
Hello from MrBillDoesMath!
Answer:
-3x - 7
Discussion:
The order of operations states that multiplication and division are done before addition\subtraction. So
-2x +5/-5x - 7 =
-2x + (5/-5x) - 7 -
-2x -x -7 =
-3x - 7
Thank you,
MrB
