I feel like it’s either 1 or 2
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:
Step-by-step explanation:
k ≤ -3-8 subtract 8 from both sides
k ≤ -11
the solution is the area to the left of a vertical line trough the point x= -11 and includes thhe line
You said that n = 5m
AND n = m + 36 .
Well then, if those two quantities are both equal to 'n', then
they must be equal to each other, and we can write
5m = m + 36
Subtract 'm' from each side: 4m = 36
Divide each side by 4 : m = 9 .
OK. We're half done.
Way back at the beginning, the first thing you told me
was that 'n' is 5 times the value of 'm'.
n = 5 (m)
Well ! Now we know what 'm' is, so
n = 5 (9) = 45 .
