10. First find the common denominator for 7/8 and 9/10. I personally chose 35/40 and 36/40. Add the two fractions up to get a irregular fraction, which is 71/40. To then get a regular fraction, subtract 40 from 71 (which leaves you with a 1 in the ones place), then take the remaining number and put it like this: 1 31/40

10. 7/8 + 9/10 = 35/40+ 36/40 which equals 71/40 = 1 31/40 is the answer
11. 1/4+2/5= 5/20+8/20 = 13/20 which is the answer

My answer may not be accurate, but try (-4, 2)

I recommend using Khan Academy if you still don't understand the concept. (no shame btw)

Step-by-step explanation:

Here is a thorough explanation.

Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set {x | −3≤x≤1} . To write this interval in interval notation, we use closed brackets [ ]: [−3,1]

5x-25=-10 Please HELP

solong [7]

Answer:

We simplify the equation to the form, which is simple to understand

5x+25=10

We move all terms containing x to the left and all other terms to the right.

+5x=+10-25

We simplify left and right side of the equation.

+5x=-15

or this is another way

Simplifying

5x = 25 + -10

Combine like terms: 25 + -10 = 15

5x = 15

Solving

5x = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '5'.

x = 3

Simplifying

x = 3

We divide both sides of the equation by 5 to get x.

x=-3

Natali [406]

The correct answer is: 
green and blue.

Explanation: 
We want to see which fractions $\frac{3}{4}$ is a multiple of. We know that $\frac{3}{4}$ is a multiple of $\frac{1}{4}$ , because $\frac{1}{4}$ *3= $\frac{3}{4}$ .

We can divide fractions to determine if $\frac{3}{4}$ is a multiple of $\frac{1}{2}$ :
$\frac{ \frac{3}{4}}{ \frac{1}{2}}$ ;

in order to divide fractions, flip the second one and multiply:
$\frac{3}{4}$ )* $\frac{2}{1}$ = $\frac{6}{4}$ =1 $\frac{1}{2}$ .
This did not divide evenly, so $\frac{3}{4}$ is not a multiple of 1/2.

Checking to see if $\frac{3}{4}$ is a multiple of $\frac{1}{8}$ , $\frac{ \frac{3}{4}}{ \frac{1}{8}}$ ;

flip the second one and multiply:
$\frac{3}{4}$ * $\frac{8}{1}$ = $\frac{24}{4}$ =6.
This divided evenly, so $\frac{3}{4}$ is a multiple of $\frac{1}{8}$ .
