Answer:
No
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.

Jazmyn uses 2 gallons of paint to paint 5 walls. He uses 4 gallons of paint to paint 10 walls. How many gallons of paint does he use per wall?
Answers
Answer:
2/5 gallons
Step-by-step explanation:
If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison
[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]
Hence, 2/5 gallons of paint is used per wall.

9. Andrew was measuring the height of the tree in his yard. Four years after it was planted, the tree was 11 feet tall. Twelve years after the tree was planted, it was 21 feet tall. Assuming the tree was growing at a constant rate, create the equation that models that growth of the tree over time. Show or explain your reasoning. (HINT: Use the two points to find the slope and use point-slope form to create an equation.)
Answers
Answer:
y=10/8x+6
Step-by-step explanation:
This is because when you plot the points you can find the slope by using rise over run and by finding the slope you can find the y intercept and that is all you need for the equation.
Answer:
first it show 11ft over 4 years so do 11/4 the answer would be 2.75 ft every year and to try doing it with the tree in 12 years

What’s the answer and how do i find slope?
Answers
You can find the slope by putting the two ordered pairs into the formula: y2-y1/x2-x1.
y2 is the second y, being 8 in your case.
x2 is the second x. Being -2 in your case.
y1 is the first y, being -6 in your case.
x1 is the first x. Being 0 in your case.
After plugging in these numbers you will get 8- -6/-2-0. This will get you 14/-2. which will equal -7, the slope.
I can explain more if you want.

Step-by-step explanation:
start at the 6 then go down 2 Y and over 5X
Answer:
See explanation below
Step-by-step explanation:
Start at (0,6) which is the y-intercept where b=6, then go down 2 units, and 5 units to the right which represents the slope m=-2/5 and mark that point. Repeat until you feel you're done and then connect the points to form the line of the equation.
For example, the next point after (0,6) would be (5,4) because by going 5 units to the right and 2 units down, we can represent this as (0+5,6-2) which is (5,4). I've attached a graph with some points to help draw the line.

A band earns $\frac{2}{3}$
of their profit from selling concert tickets and $\frac{1}{5}$
of their profit from selling merchandise. The band earns $1500 from selling concert tickets. How much money does the band earn from selling merchandise?
Answers
Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.
(2/3) / (1/5) = 10/3 = 3 1/3
Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.
This can be elaborate in such a way also.
Let suppose the total profit is $30.
then the profit from the ticket sale = 2/3 of 30 = $20
and the profit from the band merchandise sales = 1/5 of 30 = $6
Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answers
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.
