Answer:
-3x +8
Step-by-step explanation:
Apparently, you want to simplify the expression. That means you want to "collect terms", or "combine like terms."
"Like terms" are ones with the same variable structure. Here, the three terms in the expression are (-2x), (-x), and (+8). The ones that both have x as a variable are (-2x) and (-x). The way we combine these is to add the coefficients of the variable:
(-2x) +(-x) = x(-2) +x(-1)
= x(-2 -1)
= x(-3)
= -3x
So, the two "x" terms combine to give -3x. The constant term (+8) is not combined with anything. The simplified expression is then ...
-3x +8

<em>Additional comments about writing and combining terms</em>
When math symbols are written next to each other, it means they are multiplied. -2x means (-2) × (x). It can be written several ways, including ...
- -2x
- (-2)x
- x(-2)
- (x)(-2)
- (-1)(2x)
Usually, the coefficient is written in front of the variable. In the above, we have chosen to write the coefficient after the variable so that the expression shows some parallelism with the usual expression of the <em>distributive property</em>:
a(b +c) = ab +ac
x(-2 -1) = x(-2) +x(-1)
You multiply the whole number and the <span>denominator ( the bottom number in the fraction) and then add the answer of that to the numerator. Hope that helps! :) </span>
Answer:
10
Step-by-step explanation:
We start by getting the value of x
We have this as follows:
5x ≤ 43 + 11
5x ≤ 54
x ≤ 54/5
x ≤ 10.8
As we can see, the maximum integer closest to this decimal is the value 10
1/6 cups of milk remaining
Answer:
This shape has no rotational symmetry.
Explanation:
Shapes with rotational symmetry have the property of looking the same after being rotated a degree smaller than 360.
Although this shape in the image does have symmetry, it does not have rotational symmetry because there is no way for it to look the exact same after being rotated.
I hope this helps!
