  simplify

−3x+5=2(x−2)+1

−3x+5=(2)(x)+(2)(−2)+1(Distribute)

−3x+5=2x+−4+1

−3x+5=(2x)+(−4+1)(Combine Like Terms)

−3x+5=2x+−3

−3x+5=2x−3

Subtract 2x from both sides.

−3x+5−2x=2x−3−2x

−5x+5=−3

Subtract 5 from both sides.

−5x+5−5=−3−5

−5x=−8

Divide both sides by -5.

−5x−5=−8−5

x=8/5

Gary had a 40% discount for car speakers. The sale price of the speakers was $96.25. What was the original price of the speakers
Ostrovityanka [42]

Answer:

Step-by-step explanation:

If the price after the discount is subtracted is $96.25 then this is what you do

u times 0.40 x 96.25 which is 38.5 so since you are wanting to know what the price was before the discount you would add 38.5 to 96.25 and when you do that your answer is 134.75

but if you are just trying to get the discount from 96.25 you subtract 38.5 from 96.25

The quantities x and y are proportional.<br>pls help plsssss this work is due 20 min plsss helppp
Dahasolnce [82]

Answer: 2.5

Step-by-step explanation:

y = rx

substitute numbers in and solve for r

if

y = 10

x = 4

then

10 = r4

r = 10/4 = 2.5

this works for all the other numbers and always gives r = 2.5
