Like fractions are fractions with the same denominator. You can add and subtract like fractions easily - simply add or subtract the numerators and write the sum over the common denominator.
Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this:
1.Find the smallest multiple (LCM) of both numbers.
2.Rewrite the fractions as equivalent fractions with the LCM as the denominator.
When working with fractions, the LCM is called the least common denominator (LCD)
Answer:
second option
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle
Given
hypotenuse = x
and
the combined length of the legs = 2x , then
perimeter = x + 2x
Answer:
x/5
Step-by-step explanation:
To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)
f(x) = 5x
y = 5x
y/5 = x
Now that x is alone you switch the x for y and the y for x and you get:
x/5 = y
And this new y is the inverse function of f(x) ( f^-1(x))
f^-1(x) = x/5
Answer:
30 <em>pages per hour</em>
Step-by-step explanation:
6 <em>pages per </em>1/5 <em>hour </em>
6 <em>x 5 = 30</em>
<em>1/5= </em><em>one whole would be five parts</em>

So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be 
Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is 
. Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses: 
Now add up what's inside the parentheses: 
Lastly, multiply and <u>your answer will be $56.56</u>
