The ratio is 4:5 meaning out of 9 students 4 are girls and 5 are boys. If there are 36 students, 9 will go into 36 four times so if we multiply each number of the ratio by 4 it gives us the answer.
4:5
4x4 = 16
5x4 = 20
The ratio is 16:20
16 girls to 20 boys... 16 +20 = 36
Answer:
I feel like a lot of people try to get people just to do the work for them on this site.
Step-by-step explanation:
To actually find the area of this shape without using a too high level of math, you would split the shapes into geometric shapes and you should find that you have all the values to make that line up. Just remember to be careful. This will take a moment which is why i'm not doing it. Remember area = b*h area of triangle = 1/2*b*h
-1 and -6 are the integers
Answer:
7x+3y-z
Step-by-step explanation:
Starting off by separating the different variables, you should get:
(3x + 2x ) + (-z + 2z) + (3y)
Then you simplify in between the parentheses...
(5x) + (z) + (3y)
And you finally simplify the equation with only a single number of a certain variable to get your answer...
5x + z + 3y
12$ per month because if you take the 2 months money value, subtract 36 from it since that was the intial amount before she started working, and divide it by 2 thats the answer.
