0 ≠ 4. The equation is wrong, and has no true solution.

8x + 3 - 10x = -2(x - 2) + 3

Distributive property.

8x + 3 - 10x = -2x + 4 + 3

Combine like terms.

-2x + 3 = -2x + 7

Cancel like terms.

Subtract 3 from both sides.

0 ≠ 4

The midpoint of the coordinates (3, 15) and (20,8) is -

Nat2105 [25]

Answer:

The midpoint of the given coordinates is $(\frac{23}{2},\frac{23}{2})\ or\ (11.5,11.5)$ .

Step-by-step explanation:

We have given two coordinates (3,15) and (20,8).

Let we have given a line segment PQ whose P coordinate is (3,15) and Q coordinate is (20,8).

We have to find out the mid point M(x,y) of the line segment PQ.

Solution,

By the mid point formula of coordinates, which is;

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

On substituting the given values, we get;

$M(x,y)=(\frac{3+20}{2}, \frac{15+8}{2})\\\\M(x,y)=(\frac{23}{2},\frac{23}{2})$

We can also say that $M(x,y)=(11.5,11.5)$

Hence The midpoint of the given coordinates is $(\frac{23}{2},\frac{23}{2})\ or\ (11.5,11.5)$ .

Answer:

600, 1400, 3000, and 5000

Step-by-step explanation:

The profit equation can be simplified.

P = 350n -(150n +1000)

P = 200n -1000 . . . . . . . . . collect terms

P = 200(n -5) . . . . . . . . . . . factor out 200

For the given numbers n, we have ...

P = 200({8, 12, 20, 30} -5) = 200{3, 7, 15, 25} = {600, 1400, 3000, 5000}

Profits for 8, 12, 20, and 30 customers are 600, 1400, 3000, and 5000, respectively.

8 ounce (280 milligrams of calcium)
128 ounces (? milligrams of calcium)
128/8 = 16 (eight is sixteen times in 128)
Then
16 * 280 = 4,480 milligrams of calcium per gallon
