Answer:
36
Step-by-step explanation:
Let's call the # of boys and girls 5x and 3x respectively. We can write:
5x = 3x + 24
2x = 24
x = 12 so the # of girls = 12 * 3 = 36
Answer:
A. 8 inches by 6 inches.
B.
.
Step-by-step explanation:
We have been given that George had 1 sheet of paper. He cuts it into 6 inches by 5 inches and 3 inches by 6 inches.
We can see that two dimensions of small parts of paper sheet have one dimension same (6 inches), therefore, one dimension of original sheet of paper will be 6 inches.
We can figure out second dimension of original paper sheet by adding the lengths of dimension other than 6. So the second dimension will be 8 inches (5+3).
Therefore, the dimensions of our original sheet will be 8 inches by 6 inches.
Now let us figure out the total area of the original sheet of paper by multiplying 8 by 6.


Therefore. the area of original sheet of paper will be
.
Answer:
-14
Step-by-step explanation:

X = 25, y = 14.
This is possible to solve because the vertical angles (7y and 5y + 28 ; 3x +7 and 4x - 18) are equal to each other. To solve for x, just set the two x equations equal to each other. The same is done for y with the y equations.
