Sam has 12 black and white photos and 18 color photos.he wants to put the photos in equal rows so each row has either black and white photos only or color photos only. in how many rows can Sam arrange the photos

Answers

The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows.

Answer:

Step-by-step explanation:

First you have to find the GCF (greatest common factor) and the GCF is 6

Then you have to multiply 3×6 = 18, 2×6 = 12

Next add 3 + 2 = 5 because I added the first digits of the multiplying thinge

Each month Allison gets a $15 allowance and earns $100 working at the theater. She uses the expression 15x+100y to keep track of her earnings Part A Part B Part C

Answers

Step-by-step explanation:

The expression for he earning of Allison and her allowance is as follows :

15x+100y

Part A

Variables are x and y. Coefficients are 15 and 100.

Part (B)

There are two terms in this expression. + is used to separate the terms. 15x and 100y are the terms.

Part (C) As $15 shows her earning from allowances. Hence, 15x shows allowance.

[Insert generic name here] is trying to bake a yellow cake because [reasons]. This recipe will make one whole cake.

$3(1)/(4)\ cups\ of\ flour\n 2(1)/(2)\ teaspoons\ of\ baking\ soda\n (1)/(2)\ teaspoon\ of\ salt \n 1(3)/(4)\ cups\ of\ sugar \n (2)/(3)\ cup\ of\ butter \n 2\ eggs\n 1(1)/(2)\ teaspoons\ of\ vanilla\ \n 1(1)/(4)\ cups\ of\ milk$

He wants to make three cakes instead of one. How much of each item should be used in the new (scaled-up) recipe?

$3(1)/(4)*3=9(3)/(4)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ cups\ of\ flour\n 2(1)/(2)*2=4(2)/(2)=4+1=5\ \ \ \ \ teaspoons\ of\ baking\ soda\n (1)/(2)*3=(3)/(2)=1(1)/(2)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ teaspoons\ of\ salt \n 1(3)/(4)*3=3(9)/(4)=3+2(1)/(4)=5(1)/(4)\ cups\ of\ sugar$

$(2)/(3)*3=(6)/(3)=2\ \ \ \ \ \ cups\ of\ butter\n 2*3=6 \ \ \ \ \ \ \ \ \ \ \ \ eggs\n 1(1)/(2)*3 = 3(3)/(2) = 4\frac{1}2\ teaspoons\ of\ vanilla\ \n 1(1)/(4)*3=3(3)/(4)\ \ \ \ \ \ \ \ cups\ of\ milk$

I don't know exactly how your teacher wants you to write out the work, but I have it pretty simple there. It's not like math is tailored to a specific process; any sort of reasonable work should do.

Good luck!
