Answer:

To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Answer:

The information you would need to create a two-variable equation is how much was her allowance and how much money did she have. Also you would need to know how many arcade games she played and how much each one cost and how many times she rode the Ferris wheel and how much each ride cost.

Answer:

12 students

Step-by-step explanation:

<u>Below numbers are divisible by the number of students:</u>

28 - 4 = 24
39 - 3 = 36

24 = 2*2*2*3
36 = 2*2*3*3
GCF(24,36) = 2*2*3 = 12

The largest possible number of students is 12

Explain how knowing 1+7 helps you find the sum for 7+1

kakasveta [241]

We can use the concept of commutative property of addition here. We know that the addition follow the commutative property.

The commutative property of addition is given by

$a+b=b+a$

It means, if we change the order, it will not affect the result.

Therefore, using above mentioned property, we can see that

1+7 = 7+1

Hence, if we know the value of 1+7, then we can easily find the value of 7+1 because both are same.

Blizzard [7]

Answer:

rs 38.

Step-by-step explanation:

Total cost of the 80 books = 80*30 = rs 2400.

He had 60 books to sell and made a 5% loss.

Thus his income from these books was 2400 - 0.05*2400 = rs 2280.

So the selling price of each book was 2280 / 60 = rs 38.

JulsSmile [24]

Answer:

SD = 7588.09

Step-by-step explanation:

Check the distribution table attached to for the step by step solution:

The formula for the mean, $\bar{x} = \frac{\sum fx}{\sum f}$

$\bar {x} = \frac{1410040}{80} \\\bar {x} = 17625.5$

The variance , $V(X) = \sqrt{\frac{\sum f(x - \bar{x}^2)}{n-1} }$

$V(X) = \frac{4548750000}{80 - 1} \\V(X) = 57579113.92$

Standard Deviation,

$SD = \sqrt{V(X)} \\SD = \sqrt{57579113.92}$

SD = 7588.09

A park ranger spent $208 to buy 12 trees.

mixas84 [53]

Let x represent number of redwood trees and y represent number of spruce trees.

We have been given that a park ranger bought 12 trees. We can represent this information in an equation as:

$x+y=12...(1)$

$y=12-x...(1)$

We are also told that redwood trees cost $24 each, so cost of x redwood trees would be $24x$ .

Each spruce tree costs $16, so cost of y spruce trees would be $16y$ .

Since the park ranger spent $208 on trees, so we can represent this information in an equation as:

$24x+16y=208...(2)$

Upon substituting equation (1) in equation (2), we will get:

$24x+16(12-x)=208$

$24x+192-16x=208$

$8x+192=208$

$8x+192-192=208-192$

$8x=16$

$\frac{8x}{8}=\frac{16}{8}$

$x=2$

Therefore, the park ranger bought 2 redwood trees.

Upon substituting $x=2$ in equation (1), we will get:

$y=12-x\Rightarrow 12-2=10$

Therefore, the park ranger bought 10 spruce trees.
