Answer with Step-by-step explanation:

As we can see from the graph solutions are:

Graph 1: (-2,6)

it doesn't satisfy the equation 2x + 3y = 6

Graph 2: (5,-1)

it doesn't satisfy the equation 2x + 3y = 6

Graph 3: (2,2)

it doesn't satisfy the equation 2x + 3y = 6

Graph 4: (6,-2)

It satisfies both the solutions

Hence, solution of the system

2x + 3y = 6

x + y = 4 is:

(6,-2)

Given by the fourth graph

The correct answer is:  "Graph [D]:  "the fourth graph provided".
__________________________________________________
Explanation:  By looking at each graph in each of the 4 (FOUR) answer choices provided;   "Graph [D]" (the fourth answer choice) is the only graph in which two (2) of the same lines intersect at the same point with the particular coordinates: 
  "(6, -2)" ;  that are correct for BOTH of the 2 equations given.
Furthermore, we see that the coordinates for BOTH of the x and y- intercepts for BOTH of the equations given in this problem—are, in fact, points along EACH of the given corresponding 2 (two) corresponding lines in:  "Graph [D]".

There are 84 boys in the 6th grade class. If boys make up 30% of the 6th graders, how many students are in this whole 6th grade
koban [17]
<h3>Answer:  280</h3>

Work Shown:

x = number of students in the 6th grade class

30% = 30/100 = 0.30

30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84

Divide both sides by 0.30 to isolate x

0.30x = 84

0.30x/0.30 = 84/0.30

x = 280

So there are 280 students overall in the 6th grade class.

Giving brainliest pleeeaaasssse help!
lina2011 [118]

Answer:

1. Consider a hot pot taken off the stove and placed on a tile countertop. At first it cools quickly. As it cools, the difference in temperature between the pot and the room air becomes less, and so it takes a long time for the pot to lose enough heat to match room temperature. Two objects at the same temperature are said to be in equilibrium.

2.  When a liquid changes into a gas it absorbs energy. When it changes into a solid it gives off energy...If a solid (dry ice for example) is allowed to sublimate into a gas, it absorbs heat - that's why it feels cold when you touch ice. So, if a gas changes into a liquid, it give off heat as an opposite effect.  Anytime you compress a gas, it gets warmer.

Juan brought 4 Tshirts and leather jacket. The T shirts were all the same price, and the price of the leather jacket was 6 times
Alex

Let us say that:

x = the number of T shirts bought = 4

y = the number of leather jackets bought = 1

a = the price of the T shirts

b = the price of the leather jackets

 

With the given variables, we can say that the total cost is:

total cost = a x + b y

 

Since, b = 6 a, therefore:

total cost = a x + 6 a y

total cost = a (x + 6 y)

 

Since total cost is 209, therefore we can calculate for a since x and y are also given:

209 = a (4 + 6 * 1)

209 = a (10)

a = $20.9

 

<span>Therefore each T shirt cost $20.9</span>
