There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
There are infinitely many values of x and y are possible.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Two school groups go to a roller skating rink.
One group pays $243 for 36 admissions and 21 skate rentals.
The other group pays $81 for 12 admissions and 7 skate rentals.
Let x represent the cost of admission and let y represent the cost of a skate rental.
We have a system of equations,
36x + 21y = 243 {equation 1}
12x + 7y = 81 {equation 2}
Simplifying equation 1 we get,
36x + 21y = 243
Divide by 3,
12x + 7y = 81
That means, there are infinitely many solutions possible.
Therefore, there are infinitely many solutions possible.

Answer:
The first one
Step-by-step explanation:
Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall, but its length is unknown.
Each section will be a different color, so they need to know the area of each section.
so , i said 5/10x area = length * width A=10*x a= 10x
then i said you should divide , next i said 10x/5 10x in five sections is 2 in each q1 said area 10*x but x=2 so 10*2=20 is this correct?

−5.6x=−4
What is the solution to the equation?
Enter your answer as a simplified fraction in the box.
Answer: 0.714285
Step-by-step explanation:
The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.
Given :
-5.6x = -4
The following steps can be used in order to determine the solution to the equation (-5.6x = -4):
Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.
Step 2 - Write the given equation.
-5.6x = -4
Step 3 - Add 4 on both sides in the above equation.
-5.6x + 4 = -4 + 4
-5.6x + 4 = 0
Step 4 - Add 5.6x on both sides in the above expression.
-5.6x + 4 + 5.6x = 5.6x
4 = 5.6x
Step 5 - Divide 4 by 5.6 in the above expression.
[tex]x = \dfrac{4}{5.6}[/tex]
Step 6 - Simplify the above expression.
[tex]x = \dfrac{5}{7}[/tex]

Marcus has earned 353 out of 400 points (88% or B+) in Math class. He needs 90% to earn an A-. There is one test left worth 100 points. How many points does Marcus need on the test to raise his grade to an A-?
Answer:
97
Step-by-step explanation:
Marcus is aiming for an A- (90-94 percent). The question states that there is another test awaiting that is worth 100 points. In order to find the answer to the question, you need to:
1.) Add 400 + 100, to show how many points there are in total.
2.) Use the answer choices and add it to 353.
88 + 353 = 441
93 + 353 = 446
97 + 353 = 450
3.) Find the percentage of the sums.
441/500 = 88%
446/500 = 89%
450/500 = 90%
Since Marcus is aiming for an A-, we can conclude that obtaining 97 points will help Marcus achieve an A-.
An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.
Answer:
The balance in the bank after 5 years of 6.5% interest is $5,300.
Step-by-step explanation:
*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*
So every 5 years the balance earns 0.065 of 4,000 dollars.
This would make our equation:
4000 + (4000 x .065 x 5 )
= 4000 + (1300)
= 5300
The balance in the bank after 5 years of 6.5% interest is $5,300.

5,300

How do you find the height of a rectangular prism with the volume and area?
Answer:
The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.
50 s - 100
5 s - 10
s - 2
2 s - 4
Answer:
2 s - 4
Step-by-step explanation:
A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.
Because the total perimeter as mentioned of the pentagon is 10s - 20,
dividing it by 5 should find the length of each side!
Equation: (10s - 20) / 5
Once you finish dividing each digit inside the bracket you are done!
= 2s - 4
So that leaves us with 2s-4
Answer:
2 s - 4
