Question

Good luck 7•?=x x+20=p p+x=180

Answer 1

Step-by-Step explanation:

so first we define x in terms of p (or p in terms of x)

x=180-p

replace x in the equation x+20=p with 180-p

180-p+20=p

add p to each side

200=2p

p=100

so now we can find x

180-p=x

180-100=x

x=80

say z=?

7=80/z

multiply both sides by z

7z=80

divide both sides by 7

z=80/7

?=11 3/7

Answer:

80/7 or 11.429
