1 answer:
zepelin [54]3 years ago

Answer:

135 degrees

Step-by-step explanation:

(8x-7)+(12x+57)=180

combine like terms

20x+50 = 180

subtract 50 on both sides

20x = 130

divide by 20

x = 130/20

x = 13/2

x = 6.5

cpq = 12x+57

cpq = 78 + 57

cpq = 135

DENIUS [597]

Answer:

C. 500 ft

The LCM of two numbers is 60. Their GCf is 6 and their difference is 18. What are the two numbers?
Aliun [14]
LCM(x,y)=60\\&#10;GCF(x,y)=6\\&#10;x-y=18\\\\&#10;LCM(x,y)=\dfrac{|x\cdot y|}{GCD(x,y)}\\&#10;60=\dfrac{|x\cdot y|}{6}\\&#10;|x\cdot y|=360\\\\\\&#10;|x\cdot y|=360\\&#10;x-y=18\\\\&#10;|x\cdot y|=360\\&#10;x=18+y\\\\&#10;|(18+y)\cdot y|=360\\&#10;|18y+y^2|=360\\&#10;18y+y^2=360 \vee 18y+y^2=-360\\&#10;y^2+18y+81=441 \vee y^2+18y+81=-279\\&#10;(y+9)^2=441 \vee (y+9)^2=-279\\&#10;y+9=\sqrt{441} \vee y+9=-\sqrt{441}\\&#10;y=21-9 \vee y=-21-9\\&#10;y=12 \vee y=-30\\\\&#10;x-12=18 \vee x-(-30)=18\\&#10;x=30 \vee x=-12\\\\&#10;\boxed{x=30, y=12 \vee x=-12, y=-30}

Simplify your answer
Lelechka [254]

Answer:

<h2><u>0</u></h2>

Step-by-step explanation:

If 2u-6=4, let's solve for u.

Add 6 to both sides

2u-6+6 = 4+6

Simplify

2u = 10

Divide both sides by 2

u = 5

Now, we can solve u-5

5-5 = 0
