a number can be written a "x".

"minus" is a key word for subtraction.

"is" is a key word for =.

So if we put that all together, we have

x-3=5

To solve it, we have to add 3, to cancel it out, and add 3 to 5.

x-3=5

+3 +3

x=8

To find the slope take two ordered pairs and put them in form of x2-x1/y2-y1 and then you can find the slope.

(-2,17) (-3,20)

(-2)-(-3) = 1
(17)-(20)=-3

slope is 1/-3

et mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures. mB = ° mC = °

Free_Kalibri [48]

Alright, lets get started.

We have given angle A = 40°

We are also given angle B is complement of A.

Complementary angles are two angles whose sum is 90, it means

angle B = $90- A$

angle B = $90 - 40$

angle B = 50° Answer

Now given, angle C is supplement of angle B.

Supplementary angles are two angles whose sum is 180°.

Means angle C = $180 - B$

angle C = $180 - 50$

angle C = 130° : Answer

Means angle B = 50° and angle C = 130°

Hope it will help :)

562 ÷ Choose... = 14 R2

Zolol [24]

Answer:

7868

Step-by-step explanation:

⇒ This can be written algebraically (with a variable x) as:

562 ÷ x = 14

⇒ Convert the division as a fraction:

$\frac{562}{x}$ = 14

⇒ Multiply both sides by 562 to get rid of the fraction and to isolate the variable x:

562 · $\frac{562}{x}$ = 14 · 562

⇒ Simplify:

x = 7868

Answer: 7868

Hope this helps! :)
