A good way of doing this problem would be to use cross multiplication of ratios
<u />

Then cross multiply
(10 girls)(270 students)=(X girls)(18 students)
2700=18x
150=x
Answer:
Step-by-step explanation:
5x + 3 = 23 x=4
5. 4 = 3a – 14 a=6
6. 2y + 5 = 19 y=7
The beaker is holding 5 centiliters.
Y-4=3(x+2)
y-4=3x+6
y = 3x +10
so in case of choise C. we get
4 = 3*(-2) +10
4 = -6 +10
4 = 4
hope this will help you
