6x + 12 = 10x − 4 1. Solve for x using two different methods

Answers

Answer 1

Answer:

x=53/4 or 4x=53

Step-by-step explanation:

First move the variable to the left-hand side and change its sign.

6x+12-10x=-41 to 6x-10x=-41-12

Then collect the like terms

6x-10x=-41-12 to -4x=-41-12 which equals to -4x=-53

Now you divide both sides of the equation by -4

-4x=-53 to x=53 over 4 then if you want you divide which gives you x=13.25

Second way:

Kind of the same thing as the first one

Move the variable to the left-hand side and change its sign

6x+12=10x-41 to 6x=12-10x=-41

Then you collect the like terms

6x-10x=-41-12 to -4x=-41-12

Now you multiply both sides of the equation by -1

-4x=-53 to 4x=53

Answer:

x < 4

Step-by-step explanation:

Open circle (not filled in) means that the number it is on (in this case 4) is excluded. The arrow moving to the left means that x is anything less than 4. Therefore the answer is: x < 4

Answer:

x < 4

Step-by-step explanation:

The graph shows an open circle so it is less than rather than less than or equal too. Also the blue line is facing the left so x must be less than 4.

Geoffrey wants to make one planter that extends from the ground to just below his back window. The window starts 3 feet off the ground. If he wants the planter to hold 36 cubic feet of soil, name one way he could build the planter so it is not taller than 3 feet. Explain how you know.

Answers

Answer:

Step-by-step explanation:

36 / 3 = 12

12 = 4 x 3

V = L x W x H

= 4ft x 3ft x 3ft

Since Geoffrey wants to build a planter with a height of 3ft & a volume of 36ft^(3), the base of the planter should have an area of 12ft^(2).

2(3x – 5) = 8
what is the x?

Answers

Answer:

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

2*(3*x-5)-(8)=0

2 • (3x - 5) - 8 = 0

Pull out like factors :

6x - 18 = 6 • (x - 3)

6 • (x - 3) = 0

Solve : 6 = 0

Add 3 to both sides of the equation :

x = 3

Answer: x = 3

Step-by-step explanation:

2(3x-5)=8

first, you multiply 2 by 3x and -5.

6x-10=8

since we want 6x by it’s self we add 10 to its self and add it to 8 as well.

6x = 18

now we divide 6 to both 6x and 18.

x = 3
