When adding fractions, you have to make sure the bottom numbers are the same. Otherwise, you can't add them.

So currently, the bottom number for the first fraction is 5. The bottom number for the second fraction is 2.

As you can see, 5 is not the same as 2, so we need to find one number to make sure the bottom number is the same for both the fractions.

You can multiply the the first fraction by 2, and the second fraction by 5 to give you two fractions that have the same denominator (bottom number.)

So, 3/5 multiplied by 2 is the same as multiplying 3 by 2, and 5 by 2. That gives you 6/10.

1/2 multiplied by 5 is 1 multiplied by 5, and 2 multiplied by 5, which is 5/10.

Now that you have your converted fractions, you can add them and forget about the bottom number, as it's the same. When adding fractions, if the bottom numbers are equal, you leave it as it is, so the 10 stays as 10:

6/10 + 5/10 = 11/10 

Notice how I added 6 and 5 to give me 11, but I don't add 10 + 10, because I don't need to.

So the answer is 11/10.

The values (9.4,11) and (11,y) are from an inverse variation. Find the missing value and round to the nearest hundredth.
marusya05 [52]

Answer: 9.4

Step-by-step explanation:

Here the x-coordinates and y-coordinates have the inverse relation.

⇒ x\propto\frac{1}{y}

⇒ x=\frac{k}{y}

Where k is variation constant.

Since, point (9.4, 11) is from the inverse variation,

Therefore, this point must be satisfy the above condition,

That is,    9.4=\frac{k}{11}

k=103.4

Thus, the relation between the coordinates is,

x=\frac{103.4}{y}

Put x = 11, in the above function,

11=\frac{103.4}{y}

y=\frac{103.4}{11}=9.4

Answer

D. -3x + 4(2x-6) + 5

Step-by-step explanation:

-3x has nothing attached to it so leave it alone

4 times 2x equals 8x and 4 times -6 equals -24

add 5

8x-3x=5x

-24 + 5 = -19

5x - 19

Solve for y<br> 4y + 8 = 29 - 5y
andriy [413]

Answer:

7/3

Step-by-step explanation

4y+8=29-5y

First you are going to subtract 8 from both sides of the equation.

4y=21-5y

Next you are going to add 5y to each side of the equation.

9y=21

Now write it as a fraction,

9/21

Last but not least simplify.
