How do i solve 2x+6>20
lukranit [14]
Hello!

To solve 2x+6>20, you'll first need to subtract. First, you'll need to subtract 6 from 20 (20-6). Now if the 6 was negative, you would need to add 6 to 20, but for this equation you'll subtract. 

2x>14

Now you will need to divide both sides by 2. Once you've done that you'll have your answer of...

x>7

I hope this helps!

Compute the rate of discount allowed on a lawnmower that lists for $168 and is sold for $105. The rate of discount allowed is 43
kvasek [131]

Answer:

The rate of discount of a lawnmower is 37,5%

Sale price formula is

S = p - rp

where S = sale price,

r = discount percentage rate

p = the original price.

Isolating r

r= (p-S)/p

r=  ($168- $105)/$168

r=0.375

r= 37,5%
