Find X, and the two angle measures.

Snowcat [4.5K]

Answer:

x = -4

m<LMP = 77°

m<NMP = 103°

Step-by-step explanation:

Straight angles by definition have a total measure of 180°.

This means that m<LMP and m<NMP are 180° together.

Therefore m<LMP + m<NMP = 180°.

[substitution property]

(-16x + 13)° + (-20x + 23)° = 180°

[associative property of addition]

(-36x + 36)° = 180°

-36x + 36 = 180

–36 –36

-36x = 144

÷-36 ÷-36

x = -4

_________________

Since m<LMP = (-16x + 13)°.

Using substitution with x = -4:

m<LMP = (-16(-4) + 13)° = (64 + 13)° = 77°.

Since m<NMP = (-20x + 23)°.

Using substitution with x = -4:

m<NMP = (-20(-4) + 23)° = (80 + 23)° = 103°.

This is true because 77° + 103° = 180°.

Hailey and Kacie are selling candles to raise money. • Hailey is selling candles for $4 each and has already raised $160. • Kaci

marysya [2.9K]

Answer:

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey 70 candles

Kacie 40 candles

Step-by-step explanation:

Let

x------> the number of candles sold

y----> total amount raised

we know that

Hailey's equation

$y=4x+160$ -----> equation A

Please note that Hailey has already raised $160, so he has sold 40 candles.

Kacie's equation

$y=7x+70$ -----> equation B

Please note that Kacie has already raised $70, so he has sold 10 candles.

equate equation A and equation B solve for x

$4x+160=7x+70$

$7x-4x=160-70$

$3x=90$

$x=30\ candles$

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey

40+30=70 candles

Kacie

10+30=40 candles
