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 a height of one cube. In how many different ways can Jenn make the model of the park?

Answers

Answer 1
Answer: This question is basically: how many different pairs of numbers multiply up to 18?

(This is a simpler form of the question because the question is just asking how many shapes of a rectangle can Jenn create with 18 blocks)

So, the numbers that multiply up to 18 are:

1 x 18
2 x 9
3 x 6

So, the answer is: Jenn can make the model of the park in 3 different ways.

2 times x is 2x, 2 times y is 2y; therefore it is 2y +2x
2 times 3x is 6x, there is no possible way for the answer to be 5x
if you multiply the outside number by all the terms in the parenthesis you'll get;
2(x + y) = 2(x) + 2(y)= 2x + 2y giving you A as your answer in Q.#2.
And for Q.#3 the its the same steps;
2(3x) = 2(3)(x) = 6x Giving you A as your answer cause; 5x is not equivalent and the others are equivalent to 6x by multiplying as I explained you.

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beings of 5 to 1. If he wants to use a total of 90 cans how many cans of green beans should he use?

Answers

Okay, so the ratio is 5 to 1, which is a total of 6 cans. He wants to use 90 cans.

90 / 6 = 15 groups of 6 cans

Since he wants to use one can to every 5 pumpkin cans, then he will use 15 green bean cans. ( one green bean can in every group of 6 total cans )


Double check: 15 + 5 ( 5 pumpkin cans per group of 6 total cans ) * 15


15 + 75 = 90


So yes, it is true.

Answer:50

Deborah found that six of the 24 students in her class on a cell phone what is the ratio of students that own a cell phone to students that do not

Answers

so Deborah found 1/4 of the students had a cell phone and so what is left I think it will be this 4:1
Students that do own a cellphone . . . . . 6

Students that don't own a cellphone . . .  (24 - 6) = 18

Ratio of (students that do)  to  (students that do not)

         =                8                :                18

         =         1/3

I need the step by step answer for 1/3(9x+3)=3x+1

Answers

1/3 * 9x = 3x

1/3 * 3 = 1

3x + 1 = 4x

3x + 1 = 4x

4x=4x
1/3(9x+3)=3x+1

3x+1=3x+1
     -1       -1

3x=3x

3x=3x
/3   /3

x=x
