Hi.

$22-5(2x+4) \\ \\ \implies 22-10x-20 \\ \\ \implies -10x+22-20 \\ \\ \implies -10x +2$

Hence,

The correct option is $\boxed{\sf b. -10x+2}$

Thanks.

Answer:

B) $50

Step-by-step explanation:

If we know that $15 is 30% of the original price, we can set up an equation as follows:

0.3x = 15

x is representative of the original price, and 0.3 represents the 30% discount. Isolate x and solve to get 50.

-1/4 is bigger than -5/4

the closer the negative numbers are to zero, the larger they are, in this case the numerator is the same 4

Combine like terms. (−2n−2)+(6+8m)+(8m+4n)

katrin2010 [14]

Answer:

16m + 2n + 4

Step-by-step explanation:

( −2n −2) + (6 + 8m) + (8m + 4n)

−2n + −2 + 6 + 8m + 8m + 4n

(8m + 8m) + ( −2n + 4n) + (−2 + 6)

16m + 2n + 4

Triangle GHJ with vertices G(-2, 4), H(3, 6), and J(3, -2) is dilated by a factor of 1/3 centered at the origin. What are the co

Grace [21]

Answer:

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

Step-by-step explanation:

From Linear Algebra, we define the dilation of point G by the following expression:

$G'(x,y) = O(x,y) + k\cdot [G(x,y)-O(x,y)]$ (1)

Where:

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$G(x,y)$ - Coordinates of point G, dimensionless.

$G'(x,y)$ - Coordinates of point G', dimensionless.

If we know that $O(x,y) = (0,0)$ , $k = \frac{1}{3}$ , $G(x,y) = (-2,4)$ , then the point G' is:

$G'(x,y) = (0,0) + \frac{1}{3}\cdot [(-2,4)-(0,0)]$

$G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

Hey there!

To figure out how much money each person has, we need to divide.

4.44 ÷ 3 = 1.48

So each person has $1.48

Hope this helps you!

Always remember, you are a Work Of Art!
