The solution to the following equation is x=0
6x+7= 1/2x+7

True
or
False
(The 1/2 is a fraction)

Answers

Answer: True

Explanation:
If X=0 then that would make the problem 6(0)+7=1/2(0)+7. Anything multiplied by 0 is 0 so that would cancel the 6 and the 1/2. That means that you would be left with 7=7

Answer:

True

Step-by-step explanation:

To see if that is the solution, lets solve the equation.

6x + 7 = 1/2x + 7

Subtract 1/2x from each side to bring it to the right

6x - 1/2x + 7 = 7

Subtract 7 from each side to bring it to the left

6x - 1/2x = 7 - 7

Simplify it

5.5x = 0

Divide 5.5 from each side to leave x alone.

x = 0

The answer is true. I hope this helps!

Look at this inequality: 12−4x ≤ 20

Which of these shows the solution to this inequality?

Question options:

Answers

Answer: The last line is the answer

12 - 4x < 20

20 - 12 = 8

-4x = 8

-4/4 = 8/-4

x = -2

New inequality: x > -2

Step-by-step explanation:

The correct option is d. The solution to the linear  inequality 12 - 4x ≤ 20 is x ≥ -2 by solving the inequality.

To solve this inequality,  to isolate the variable x.

Step 1

subtract 12 from both sides of the inequality:

        [tex]12 - 12 - 4x \leq 20 - 12,[/tex]

which simplifies to

         [tex]-4x \leq 8.[/tex]

Step 2 :

Divide both sides of the inequality by -4. However, when  divide by a negative number, the direction of the inequality sign must be flipped. So   x ≥ -2, indicating that x is greater than or equal to -2.

Therefore, the solution to the inequality is x ≥ -2. The correct option is d.

For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total cost of the meal is $32 and is represented by the equation 2x + 18 = 32. How much does each sandwich cost?
A) $14
B) $22
C) $7
D) $28

Answers

Answer:

C

Step-by-step explanation:

thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.

First, subtract 18 from both sides to eliminate it.

2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14

Next, separate the 2 from the x by dividing it from both sides:

2x = 14 ----> 2x/2 = 14/2 ----> x = 7

By solving this equation, we find that x, or one sandwich, costs $7.
