How many solutions are there to the equation below?
Anton [14]

Answer:

B. Infinitely Many

Step-by-step explanation:

Step 1: Distribute

5x + 48 + 7x = 12x + 48

Step 2: Combine like terms

12x + 148 = 12x + 48

If the 2 lines are the same, which they are, they are the same lines. That means there are an infinite amount of solutions. If they had the same slope but different y-intercepts, there would be no solutions because the lines are parallel. Any other pair of equations would have 1 solution.

Determine if 3√10 /4 is in simplest form. if the expression is not in simplest form explain why? HELP PLEASE
emmasim [6.3K]

The notation in its current form isn't entirely clear.

Did you mean to write \frac{3\sqrt{10}}{4}? The 4 isn't in the square root.

If so, then the expression is in simplest form because we cannot simplify \sqrt{10} any further (note how 10 doesn't have any perfect square factors other than 1).

Also, the 3/4 portion is fully reduced already.

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

Or,

Did you mean to write 3\sqrt{\frac{10}{4}} ? This time the 4 is inside the square root.

If so, then we can simplify like this

3\sqrt{\frac{10}{4}}\\\\\frac{3\sqrt{10}}{\sqrt{4}}\\\\\frac{3\sqrt{10}}{2}\\\\

This means that 3\sqrt{\frac{10}{4}}=\frac{3\sqrt{10}}{2}\\\\
