Ipicked 4 times as many green peppers as red peppers. if i picked a total of 20 peppers how many peppers did i pick?

16 green and 4 red pepper

Let green peppers = g, let red peppers = r.

g = 4r

g + r = 20

Plug in 4r for g

4r + r = 20

Simplify. Combine like terms

4r + r = 20

5r = 20

Isolate the r. Note the equal sign. What you do to one side, you do to the other. Divide 5 from both sides

5r/5 = 20/5

r = 20/5

r = 4

There are 4 red peppers.

Plug in 4 to one of the equations

g = 4r

g = 4(4)

g = 16

There are 16 green peppers.

4 red peppers, 16 green peppers

hope this helps

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
