The answer is 12.5 because 75 divided by 6 is 12.5
Answer:
(-2/5, 1/5)
Step-by-step explanation:
A graphing calculator nicely provides a solution to equations when graphing is an option.
(x, y) = (-2/5, 1/5)
B + g = 42
b = 2/5g
2/5g + g = 42
2/5g + 5/5g = 42
7/5g = 42
g = 42 / (7/5)
g = 42 * 5/7
g = 210/7
g = 30 <== there are 30 girls
b = 2/5g
b = 2/5(30)
b = 60/5
b = 12 <=== there are 12 boys
Answer:
The scale factor is now 3
Step-by-step explanation:
6/2=3
12/4=3
The smaller square was increased by the scale factor of 3
