Answer:

A. (-6,-5)

and 2(-6)-3(-5) is equal to -12-(-15) and a - plus a - equals a +

so our new equation is -12+15=3-----True

Answer:

-148/3

Step-by-step explanation:

hey, this is a fraction problem

all of these denominators are already the same which makes it really simple :)

okay so first we can make this

-364/9+102/9-182/9

we just have to add the numerators together

-364+102-182=-444

so it would be -444/9

this simplifies to

-148/3

we did that by dividing both the numerator and denominator by 3

-148/3 also equals

-49 1/3

-49.3333333333 in decimal form

Hello!

Explanation:

First, you had to do is multiply by 3 from both sides of an equation.

$3*\frac{1}{3}b=4*3$

And then simplify by equation form. You can also multiply by the numbers.

$4*3=12$

$12/3=4$

$12/4=3$

$3*4=12$

Answer: $b=12$

<u><em>*The answer must have a positive sign.*</em></u>

Hope this helps!

Thanks!
