Answer:

(4, -1)

Step-by-step explanation:

Given:

C(1, -6)

D(7, 4)

Required:

Midpoint of CD using $M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$

SOLUTION:

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

Let $C(1, -6) = (x_1, y_1)$

$D(7, 4) = (x_2, y_2)$

Thus:

$M(\frac{1 + 7}{2}, \frac{-6 + 4}{2})$

$M(\frac{8}{2}, \frac{-2}{2})$

$M(4, -1)$

Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the

Alenkinab [10]

Answer:

The estimated area is $416\frac{13}{16}\ ft^{2}$

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

$9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft$

$14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft$

step 2

Find the area of one wall

$(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}$

step 3

Multiply the area of one wall by 3

$(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}$

step 4

Convert to mixed number

$\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}$

Moises ate 10% of the candies in the bag. If Moises ate 16 candies, how many candies were there total in the bag?

Viktor [21]

Answer:

160

Step-by-step explanation:

10% of the candies is 16, and to get 100% from 10% is to multiply by 10.

So 10% *10 = 100%, then by association if 16 = 10%, then 16*10 will be the total 100%.

You have saved $342$342 and want to go shopping for a few things. You buy a pair of shoes for $73$73, a pair of jeans for $38$38

Xelga [282]

The answer is $162 you take the prices of what she bought and add them together which is $73+$38+$64=$180
then you subtract the $180 from $342 which is $342-$180=$162
so the answer is $162

$342 - 180 = 162$

What is the equation 8x-3y=6-4x in Stanford form?

IgorLugansk [536]

Answer:

$12x - 3y = 6$

Step-by-step explanation:

Standard form is written this way: $Ax+By=C$

However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.

So, to do this, we have to combine like terms.

The only like terms that can be combined are -4x and 8x.

So, we add 4x to both sides, and we get: $12x - 3y = 6$ .

Pls help due ASAP <br> Show workings please!!!

Vlad [161]

Answer:

AB=8

Step-by-step explanation:

First, you get figure out x. Since both sides are equal, use the equation x+3=2x-2, then subtract x from both sides, 3=x-2, and then add 2 to both sides, x=5. Then use one of the equations to get the length of the side, I used x+3=8, which is your answer.

(hope this helps :P)
