Answer:

x=23

Step-by-step explanation:

When realizing that the total degrees of a line = 180 you can set the equation to that number.

So that it would look like this-

3x+18+93=180

then you would combine like terms (18+93=111)

3x+111=180

Subtract 111 to start to get x by its self

180-111=69

then it would look like this

3x=69

Divide by 3 and then you get the correct answer of 23!

Answer:

x=23°

Step-by-step explanation:

93°+(3x+18)°=180°

93°+3x+18°=180°

111°+3x=180°

3x=180°-111°

3x=69°

x=69°:3

x=23°

(12y2<br> + 17y - 4) + (9y2<br> - 13y + 3) =
Anna [14]

Answer:

21y^{2} +4y-1

Step-by-step explanation:

Hello!

(12y^{2} +17y-4)+(9y^{2} -13y+3)

For this, we can combine like terms

12y^{2} +9y^{2}=21y^{2}

17y - 13y = 4y

-4 + 3 = -1

Combine the answers and we get

21y^{2} +4y-1

Hope this Helps!

kogti [31]

Answer:

Discount rate=33%

Step-by-step explanation:

Step 1

Determine the discounted amount as shown;

A=I-F

where;

A=discounted amount

I=initial price/original price

F=final price after discount

In our case;

A=unknown

I=$75

F=$50

replacing;

A=(75-50)=25

The discounted amount=$25

Step 2

Determine the discount rate using the formula;

Discount rate=(discount amount/original amount)×100

Discount rate=(25/75)×100=33.33%

Discount rate=33%
