Hey!

-------------------------------------------------

Solution:

-5x + 15 = 35 - 10x

~Subtract 15 to both sides

-5x + 15 - 15 = 35 - 10x - 15

~Simplify

-5x = 20 - 10x

~Add 10x to both sides

-5x + 10x = 20 - 10x + 10x

~Simplify

5x = 20

~Divide 5 to both sides

5x/5 = 20/5

~Simplify

x = 4

-------------------------------------------------

Answer:

x = 4

Answer:

x = 4

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-5*x+15-(35-10*x)=0

Pull out like factors :

5x - 20 = 5 • (x - 4)

_________________________________________

Solve : 5 = 0

This equation has no solution.

A a non-zero constant never equals zero.

_________________________________________

Solve : x-4 = 0

Add 4 to both sides of the equation :

x = 4

padilas [110]

Answer:

f(x)=2(x+7)^2-103

Step-by-step explanation:

$f(x)=2x^{2} +28x-5\\=2(x^2+14x)-5\\=2(x^2+2(7)x+7^2-7^2)-5\\=2(x+7)^2-2(49)-5\\=2(x+7)^2-103$

If you can buy 15 bags of potatoes for $20, then how many can you buy with $4?

Mekhanik [1.2K]

Answer:

Step-by-step explanation:

15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4

now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.

you could do 15/20 is 0.75

0.75 times 4 is 3, so $4 can buy you 3 bags.

Start with parenthesis first.
so a+a+2a+48
Then add all like terms.
4a=48
Then solve for a by dividing 4 from 48.
a=12
