Hi,

Let's simplify step-by-step.

2y^2−3y^3−6y^2+5y^3

=2y^2+−3y^3+−6y^2+5y^3

Combine Like Terms:

=2y^2+−3y^3+−6y^2+5y^3

=(−3y^3+5y^3)+(2y^2+−6y^2)

=2y^3+−4y^2

Answer:

=2y^3−4y^2

Have a great day!

How do you divide 3/8 by 6/7 in simplest form
Ipatiy [6.2K]

Answer:

7/16

Step-by-step explanation:

First, it is good to know that when you divide fractions, you are <em>multiplying it's reciprocal</em>.

<em>6/7's reciprocal is 7/6, since the reciprocal is \frac{1}{6/7}</em>

3/8 / 6/7 =

<u>3/8 * 7/6</u>

Now that we have that, we can just multiply the two:

3/8 * 7/6 =

21/48 =

<u>7/16</u>

Hope this helped :)

AnnZ [28]
ANSWER

The system of equations are,

J - 2M = 0
and

J + M = 21

EXPLANATION

Let J = John's age and M = Mary's age

The first statement says,

"John is twice as old as Mary."

We can write this mathematically as,

J = 2M

or

J - 2M = 0...eqn1

The second statement says,

"the sum of their ages is 21." Mathematically, we can write this one too as,

J + M = 21...eqn2
