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!

Sami purchased 5 comic books priced as shown.

$4.50 $3.75 $3.95 $2.19 $3.24
If sales tax is 9%, what is the total price Sami paid? Round to the nearest cent, if necessary.

Answers

Answer:

$19.23

Step-by-step explanation:

First, add the prices of all 5 comics together. That should equal $17.63. The tax is 9% so that would be 1.5867 or $1.60. In total, Sami paid $19.23.

19.21

adding all the totals together gives you 17.63 . the sales tax is 1.5867 . add that to the 17.63 and you’ll get 19.21

Answer:   x = 100

=========================================================

Explanation:

The triangles are similar. We can prove this through the angle angle similarity postulate.

This means we can set up the proportion below to solve for x

(short horizontal)/(long horizontal) = (short vertical)/(long vertical)

12/150 = 8/x

12x = 150*8 .... cross multiply

12x = 1200

x = 1200/12 ... divide both sides by 12

x = 100

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

As confirmation:

12/150 = 0.08

8/100 = 0.08

This shows that 12/150 = 8/100
