Answer:

Here to help! See explanation

Step-by-step explanation:

Hey there! It's really simple once you get the hang of it, I'll show you!

Example:

\frac{1}{3} + \frac{3}{4}

First, we have to remember that we can't add fractions with different denominators. So we have to look for the least common denominator, also known as the least common multiple.

In this case, the smallest number that both 3 and 4 make is <em>12.</em>

Now, we have to multiply both fractions by what it takes to get to twelve. 3 has to be multiplied by 4, and 4 by 3.

( \frac{1}{3} )*4 = \frac{4}{12} \\\\

(\frac{3}{4} ) *3= \frac{9}{12}

Now that we have the same denominator, all we have to do is add the numerators.

\frac{4}{12} + \frac{9}{12} =\frac{13}{12}  = 1\frac{1}{12}

I hope this helped!

Given any two arcs, the larger of the arcs is always called a minor arcTrueFalse
GrogVix [38]

When we have two arcs in a circle, one larger and one smaller, one will be called the minor arc and the other the minor arc.

The name of the arc depends on its size, for example, given the following green and yellow arcs, the green, which is smaller, will be the minor arc:

Therefore, the larger arc is always called Major arc, not minor arc.

The statement is False.

Answer: False

HELP ASAP 15 POINTS!!!<br> What is the solution to this equation?<br> 6(x-5)=4x+20
Andre45 [30]

Answer:

<h2><u><em>x = 25</em></u></h2>

Step-by-step explanation:

What is the solution to this equation?

6 * (x - 5) = 4x + 20

6x - 30 = 4x + 20

2x = 20 + 30

2x = 50

x = 50 : 2

x = 25

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

check

6 * ( 25 - 5) = 4 * 25 + 20

6 * 20 = 100 + 20

120 = 120

the answer is good
