Answers

Answer 1

Answer: Simple....

4y-y+11=18

You know you want to find y so just isolate the variable....

4y-y+11=38

Add the y's..

3y+11=38

Now, subtract 11 to isolate y...

3y+11=38
-11 -11

3y=27

Now...divide...

$(3y)/(3) = (27)/(3)$

y=9

Thus, your answer.

Answer 2

Answer: Hi There! :)

Solve 4y − y + 11 = 38.9
−9
3.8
8.6

Answer is 9! :P

1.Simplify 4y−y+114y−y+11 to 3y+113y+11
3y+11=38

2.Subtract 11 from both sides3y=38−11

3.Simplify 38−11 to 27
3y=27

4.Divide both sides by 33
y=27/3

5. Simplify 27/3 to 99
y=9

Therefore, Answer is 9! :P

Determine the time needed to deliver 72 papers at rate of 9 papers in 18 minutes.

Answers

Answer: The required time needed to deliver 72 papers is 2 hours 24 minutes.

Step-by-step explanation: Given that 9 papers are delivered in 18 minutes.

We are to determine the time needed to deliver 72 papers.

We will be using the UNITARY method to solve the problem.

We have

Time needed to deliver 9 papers = 18 minutes.

So, time needed to deliver 1 minute will be

$(18)/(9)=2~\textup{minutes}.$

Therefore, time needed to deliver 72 papers is given by

$2*72=144~\textup{minutes}=(120)/(60)~\textup{hours},24~\textup{minutes}=2~\textup{hours}~24~\textup{minutes}.$

Thus, the required time needed to deliver 72 papers is 2 hours 24 minutes.

So you need to find out time. What you do is divide 72 by 9 to get 8. Once you get 8, you have to multiply it by 18. Your answer is then 144 Papers

Jenn will use 18 connecting cubes to make a model of a park. The model will be in the shape of a rectangle and will have the height of one cube. In how many ways can Jenn make the model of the park?

Answers

Given Situation : Jenn used 18 connecting cubes to make a model.
Jenn wants her model to be a rectangle shaped and have the height of 1 cube.
Now, We need to find the numbers of ways will Jenn use her model.
=> First we need to find the factors of 18
=> 18 x 1 equals to 18
=> 9 x 2 equals to 18
=> 6 x 3 equals to 18
As we can see, 18 has 3 possible ways. Therefore, Jenn will have 3 ways to model her triangle depending on the choice she wants.

What is 2 2/3 - 3/5?

Answers

2 2/3 - 3/5

First, we can start by changing 2 2/3 to an improper fraction. To do this, we can use the rule: a b/c = ac+b/c. All we need to do is insert our numbers into the form of the rule.
$(2 * 3 + 2)/(3) - (3)/(5)$

Second, we can now start simplifying. (2 × 3 = 6 and 6 + 2 = 8).
$(8)/(3) - (3)/(5)$

Third, now we have change our denominators to be the same. To do this, we can start out by finding the least common denominator (LCD). List the multiples of both of the current denominators (3 and 5) and find the first common one.

Multiples of 3: 3, 6, 9, 12, 15
Multiples of 5: 5, 10, 15

Since 15 is our first common multiple, it is now our LCD.

Fourth, now we can multiply to change our denominators. Using our current denominators, we have to multiply by let's say (x / a variable). Basically, what can you multiply by 3 to get 15? That would be (3 × 5 = 15). For our other fraction, what would we multiply by 5 to get 15? (5 × 3 = 15). Remember, whatever you do to the bottom you must do to the top.
$(8 * 5)/(3 * 5) - (3 * 3)/(5 * 3) = (40)/(15) - (9)/(15)$

Fifth, we can now combine our denominators, which will make us have to add both of the numerators together.
$(40 - 9)/(15) = (31)/(15)$

Sixth, our last step is to convert the fraction into a mixed fraction. How you do this is to divide the numerator by the denominator. We would set up something like this: 31 ÷ 15 = 2.066667. That decimal in fraction form is 2 1/15, which is our answer.
$2 (1)/(15)$

Answer in fraction form: $\fbox {2 \ 1/15}$
Answer in decimal form: $\fbox {2.0667}$

Answer:

Answer in fraction form: {2 1/15}
