Answer:
16 girls
Step-by-step explanation:
If you have 12 boys, and the ratio is 3;4, that means you multiplied 3 times 4. To find the answer to this problem, you need to multiply 4 by 4 because you multiplied 3 by 4, and you always have to multiply or divide by the same thing if its a ratio.
Answer:
B = (6, 4)
Step-by-step explanation:
You know that the midpoint is calculated as ...
M = (A +B)/2
Solving this for B, we find ...
2M = A + B
B = 2M - A
Filling in the coordinate values, we get ...
B = 2(5, -2) -(4, -8) = (2·5-4, 2(-2)+8)
B = (6, 4)
Answer:
4(xy + 3w + 3z)
Step-by-step explanation:
The GCF is 4, so you can take that out and put it in front of the parentheses. Then you just divide all of the terms by 4 (4xy / 4 = xy; 12w / 4 = 3w; 12z / 4 = 3z), etc.
