Answer:

X = 5

Step-by-step explanation:

Angles on a straight line=180°

180-151=29°

sum of angles in a triangle= 180°

11x-1+20-3+29=180

11x+20x-3-1+29=180

31x+25=180

31x=180-25

31x=155

divide both sides by 31

X=5

(11x-1)°= 55-1= 54°

(20x-3)°= 100-3= 97°

54°+97°+29°=180°

Yvette is starting a jewelry business. She spends $120 on supplies and makes 18 necklaces. She wants to earn a profit equal to 3

kiruha [24]

Yvette wants to earn a profit of $360, then. That means she has to make a total of $480. 480 divided by 18 is 26 and 2/3. That basically rounds up to $26.67.

480 = 18x

360 = 18x - 120

120(3) = 18x - 120

(I'm not that good at this, so don't take my word for it)

5+k-5k=-4k+6 solve for k

marissa [1.9K]

Hey there

the answer is

5+k−5k=−4k+6

5+k+−5k=−4k+6

(k+−5k)+(5)=−4k+6

−4k+5=−4k+6

−4k+5+4k=−4k+6+4k

5=6

5−5=6−5

0=1

thank you

best regards
