Answer:

a = 55

Step-by-step explanation:

By exterior angle theorem:

a+10 + 44 = 2a

a= 55

Here's the proof:

say a+10 = x and 44 = y

Thus the remainng angle is 180 - x-y

How do I find the area?

Answers

Answer:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square, you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

Base x Width x Height

A store buys sweaters for $8 and sells them for $26. How many sweaters
does the store need to sell to make a profit of $990?

Answers

Answer:

55

Step-by-step explanation:

55 x 26 = 1430

55 x 8 = 440

1430 - 440 = 990

The store need to sell 55 sweater to earn $ 990 as profit.

Profit and Loss:

Let us consider that, number of sweater needed to sell be x.

Since, cost price of one sweater is $8.

So that, cost price of x sweater[tex]=8x[/tex]

Selling price of one sweater is $26.

So that, selling price of x sweater[tex]=26x[/tex].

As we know that,

           [tex]S.P-C.P=Profit\\\\26x-8x=990\\\\18x=990\\\\x=990/18=55[/tex]

Hence, the store need to sell 55 sweater to earn $ 990 as profit.

Step-by-step explanation:

3 x 2x = 6x, which is how you get the 6x

and theres  a subraction sign so we know to put a - there.

Answer:

6x - 18

Step-by-step explanation:

3(2x - 6) =

("... - 6" means that whatever we do with the 6, we have to remember that it's negative)

3(2x - 6) =

3 * 2x + 3 * (-6) =

6x + (-18) =

(if we add a negative number then it's the same as subtracting that number)

6x + (-18) = 6x - 18
