Hey there!
ANSWER: 
EXPLANATION:
To find the answer to your question, you will need to add.

First, multiply the denominator.

So the denominator will be 20.
Now move on to the numerator. Multiply 5 by 3.

Now multiply 4 bu 2.

If you want to get the numerator, add what you got after multiply.

The numerator is 23. So now let's complete the fraction.

This is your answer!
Hope this helps!

Answer:
2
Step-by-step explanation:
1,3,4 are arithmetic sequences
2 is a geometric sequence
5 seconds
because that is the positive zero of that equation
So it is an isosceles triangle that means that the bottom two angles are equal...
so
40 = 5x
divide both sides by 5 and you get 8
now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40
You are correct!!! :)
3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like:

= x
Fourth, simplify

to

/ Your problem should look like:

= x
Fifth, switch sides. / Your problem should look like: x =
