Answers

Turn the mixed numbers into improper fractions:
-5 5/8 = - 45/8
-4 7/12 = - 55/12

Remember, when you divide by a fraction, you take its reciprocal and multiply it:
(-48/8) / (-55/12) = (-48/8) x (-12/55)

Simplify the fraction:
72/55

help idk how to do math

use the distributive property

Answers

Answer:

Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.

That probably isn't a good answer, here's what I found on google:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Step-by-step explanation:

I'll do #10 as an example:

(x-5)y

distribute the numbers- y(x)-y(5)

without the parentheses- yx-y5

you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.

Here's #11:

-4(2a-3b+c)

distribute the numbers- (-4*2a)-(-4*3b)+(-4c)

solve- -4*2= -8

-4*3= -12

-8a-(-12)b+4c

*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing

Hope this helps you.

what two numbers multiply to -36 and add up to 5

Answers

Answer:

9 and -4

Step-by-step explanation:

Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

First, test if they multiply to -36:

9(-4)

= -36

Then, check if they add up to 5:

9 + (-4)

= 5

So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5
