Answer:

graph B

Step-by-step explanation:

Given

3y - 5x < - 6

Since the inequality is < then the line must be broken

If ≤ then line would be solid

The only possible graphs are B and D

Choose a test point in the shaded region of each graph and check validity

graph B (2, 0) ← substitute into left side of inequality

0 - 5(2) = 0 - 10 = - 10 < - 6 ← this is valid

graph D (0, 0 ) ← substitute into left side of inequality

0 - 0 = 0 > - 6 ← this is not valid

Hence graph B is the correct graph

There are 24 students in homeroom 218. 7/12 of the students are girls. How many girls are in homeroom 218?
hichkok12 [17]

There are 14 girls in HR 218 because 24/12 is 2, meaning that the ratio needs to be multiplied by 2/2 in order to figure out what 7/12 is.  7/12*2/2 is 14/24, therefore there are 14 girls in HR 218.
