Which of these correctly explains the solution of the system of equations shown
borishaifa [10]

The solution of the system of equations is the point (-6, 6), so the correct option is B.

<h3>Which statements are correct about the system of equations?</h3>

Here we have the system of equations:

2x + 3y = 6

x + 3y = 12

First, let's write these two lines in the slope-intercept form:

y = (6 - 2x)/3 = 2 - (2/3)*x

y = (12 - x)/3 = 4 - (1/3)*x

Now, because "y" is the represents the same variable in both equations, we can write:

2 - (2/3)*x = y = 4 - (1/3)*x

Now we can solve that for x.

2 - (2/3)*x =  4 - (1/3)*x

2 - 4 = (2/3)*x - (1/3)*x

-2 = (1/3)*x

3*(-2) = x = -6

Now, to get the y-value of the solution we can evaluate any of the two lines in x = -6, evaluating the first we get:

y =  4 - (1/3)*x = 4 - (1/3)*(-6) = 4 + 2 = 6

Then the solution of the system is the point (-6, 6). Then the correct statement is B:

"The values of x= -6 and y= 6 satisfy both the equations; therefore, (-6, 6) is the solution."

You're at a clothing store that dyes your clothes while you wait. You get to pick from 4 pieces of clothing
Zielflug [23.3K]

1 / 12 is the probability that you'll end up with an  orange hat.

<u>Step-by-step explanation:</u>

Given that,

  • There are 4 piece of clothing ⇒ shirt, pants, socks, or hat
  • There are 3 possible colors ⇒ purple, blue, or orange

<u>To find the total number of outcome :</u>

Total outcomes ⇒ (number of clothes) × (number of colors)

⇒ 4 × 3 = 12

 Therefore, there will be 12 different possibilities.

<u>The 12 different outcomes are :</u>

⇒ Purple shirt, blue shirt, orange shirt

⇒ Purple pants, blue pants, orange pants

⇒ Purple socks, blue socks, orange socks

⇒ Purple hat, blue hat, and orange hat.

Now, the probability that you'll end up with an  orange hat if you choose on random of 12 possibilities ⇒ No.of orange hats / Total no.of outcomes.

∴ P(orange hat) = 1 / 12

Josh is going to the store to buy candy. Bags of candy corn cost $3 and bags of chocolate cost $5. He needs to buy at least 20 b
tino4ka555 [31]

Answer:

x + y ≥ 20

3x + 5y > 60

Step-by-step explanation:

Let

Bags of candy corn = x

Bags of chocolate = y

Cost of bags of candy corn = $3

Cost of bags of chocolate = $5

He needs to buy at least 20 bags of candy and he cannot spend more than $60

system of linear inequalities to model the situation.

x + y ≥ 20

3x + 5y > 60

The system ot inequalities which models the situation

x + y ≥ 20

3x + 5y > 60
