Answer:

I dont know the answer but I found out how you figure out if lines are supplementary

Step-by-step explanation:

1) let the measure of one of the supplementary angles be a

2) measure of the other angle is 2 times a

3) so the measure of the angle is 2a

4) if the sum of the two angles is 180 degrees then the angles are supplementary

Answer:

1. $67.72

2. It's correct.

Step-by-step explanation:

1.

bill: $68.89

discount: $10

tip: 15%

Calculate the total with the discount.

68.89-10=58.89

Now calculate 15% of that.

Convert 15% to decimal by dividing by 100

\frac{15}{100}=0.15

Multiply

0.15(58.89)=8.83

Add this to the original amount.

58.89+8.83=67.72

----------------------------------------------------------------------------

Calculate 20% of 148.25

Convert 20% to decimals by dividing by 100

\frac{20}{100}=0.20

Multiply

0.20(148.25)=29.65 This is how much they will tip.

Add this to the original bill;

148.25+29.65=177.90

The distributive property can be applied to which expression to factor 12x3 – 9x2 + 4x – 3?
Arturiano [62]

Answer:

(4x - 3)(3x² + 1)

Step-by-step explanation:

Given

12x³ - 9x² + 4x - 3 ( factor the first/second and third/fourth terms )

= 3x²(4x - 3) + 1(4x - 3) ← factor out (4x - 3) from each term

= (4x - 3)(3x² + 1) ← in factored form
