<em><u>True staments are:</u></em>

The y-variable will be eliminated when adding the system of equations

There is only one solution to the system of equations

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

x + 6y = 16 ----- eqn 1

8x - 6y = -2 ---- eqn 2

We have to solve the system of equations

When we add eqn 1 and eqn 2, then y term will get eliminated

Let us add eqn 1 and eqn 2

x + 6y + 8x - 6y = 16 - 2

6y and -6y will get eliminated

Thus, y-variable will be eliminated when adding the system of equations

x + 8x = 14

9x = 14

x = 1.55

Substitute x = 1.55 in eqn 1

1.55 + 6y = 16

6y = 16 - 1.55

6y = 14.45

y = 2.408

Thus the solution is x = 1.55 and y = 2.408

There is only one solution to the system of equations

Jane has 18 juice boxes, 24 bags of peanuts and 36 apples. She wants to make snack bags with same number of each thing in each b
pishuonlain [190]

Answer:  6 snack bags.

Step-by-step explanation:

For this exercise it is important to remember the Greatest Common Divisor (GCD). This is defined as  the largest positive intener by which  you can divided evenly "n" numbers.

In  this case, you know that Jane has  18 juice boxes, 24 bags of peanuts and 36 apples. Therefore, the steps are the following:

1. You need to descompose 18, 24 and 36 into their prime factors, as below:

18=2*3*3=2*3^2\\\\24=2*2*2*3=2^3*3\\\\36=2*2*3*3=2^2*3^2

2. Now you must choose the common ones with the smallest exponent and multiply them.

Then, you get:

GCD=3*2\\\\GCD=6

Therefore, the greatest number of snack bags that Jane can make is:  6 snack bags.

which expression is equivalent to the product 2x(x+2) (x-3)? A. 12x to the third - 12x ) B. 2x to the third - 4x squared - 6) C.
Law Incorporation [45]

Answer:

Option 4 is the correct option.

Step-by-step explanation:

We need to solve the expression 2x(x+2)(x-3)

Multiplying the terms with each other we get,

2x(x+2)(x-3)\\=2x(x^2 -3x+2x-6)\\=2x(x^2 -x -6)\\=2x^3 -2x^2 -12x

Option 4 is the correct option.
