Answer:

Step-by-step explanation:

To determine if x = 7 is a solution.

Substitute x = 7 into the equation and if left side equals right side then it is a solution

3(7) - 4 = 21 - 4 = 17 ≠ 15

Then x = 7 is not a solution to the equation

Strike441 [17]

Answer:

Let's find out!

Step-by-step explanation:

So we have to set up an equation

Let x= # of ribbons that can be cut

Thus:

$\frac{1}{6}x =\frac{6}{7} \\x=\frac{6}{7} *\frac{6}{1} \\x=\frac{36}{7}$

So, we cannot have 36/7 ribbons! It's not possible!

So we just simplify!

$x=5\frac{1}{7}$

There we go! She can cut 5 ribbons off!

I'll let you figure out the last one!

Hope this helps!
