I think the answer is 61 because :
If you split the six numbers into little groups :
66 + 7 = 73
13 + 8 = 21
52 + 9 = 61
10 + 10 = 20
You see the pattern is add one more too each group
Therefore, the answer is 61

Find the midpoint of the line segment with the endpoints (1, 0) and (2, -10).

Mariulka [41]

Answer:

$\bigl(\frac{3}{2},-5\bigr)$

or in decimal form

$(1.5,-5)$

Step-by-step explanation:

The midpoint of the line with endpoints $(x_1,y_1)$ and $(x_2,y_2)$ is $\bigl(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\bigr)$ . just take the average between the points

so given the points (1,0) and (2,-10)

$x_1=1$

$y_1=0$

$x_2=2$

$y_2=-10$

the midpoint is found as follows:

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

$\bigl(\frac{1+2}{2},\frac{0-10}{2}\bigr)$

$\bigl(\frac{3}{2},\frac{-10}{2}\bigr)$

$\bigl(\frac{3}{2},-5\bigr)$

or in decimal form

$(1.5,-5)$

PLEASE HELP ME I NEED HELP ASAP!!!! PLEASE HELP ON A AND B

Answer:

Step-by-step explanation:

The opposite sides of the rectangle are of equal length.

Therefore we have the system of equations:

$\left\{\begin{array}{ccc}3y=2+x&\text{subtract 2 from both sides}\\3x=2+x+5y&\text{subtract x from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}3y-2=x&(*)\\2x=2+5y&(**)\end{array}\right$

Substitute from (*) to (**):

$2(3y-2)=2+5y\qquad\text{use distributive property}\\\\(2)(3y)+(2)(-2)=2+5y\\\\6y-4=2+5y\qquad\text{add 4 to both sides}\\\\6y=6+5y\qquad\text{subtract 5y from both sides}\\\\\boxed{y=6}$

Put the value of y to (*):

$x=3(6)-2\\\\x=18-2\\\\\boxed{x=16}$

Calculate the width and the length:

$3x = 3(16) = 48\\\\3y = 3(6) = 18$

The perimeter:

$P = 2w + 2l\\\\P = (48)(18)=864\ in$
