If the ratio is 6:7 the students should divide nicely into 6+7=13 parts. Six of those parts are girls, seven of those parts are boys.
364 / 13 = 28
So 6 × 28 = 168 girls
Answer: 168
Check:
7 × 28 = 196 boys
168 + 196 = 364, good
I think it's c I'm not too sure
Y = mx + b
in this case m = 2 and b = 1 so
equation
y =2x + 1
hope this helps
