Answer:
there 18 girls
Step-by-step explanation:
40% of 30 = 12
this means there are 12 boys
30-12 = 18
there 18 girls
<span>Since y=4, when x=-2, plug it into the formula above, and you have
y=kx
4=k(-2)
Solve for k, k=-2
</span><span>Now, y = -2x, so if x=30</span>y=-2*30=-60.
25X4=100
4X_=88
88÷4=22
So she got 22 problems correct.
