Answer:
63
Step-by-step explanation:
Multiply 120 by 0.40 to get 40%:
120 x 0.40 = 48
So 48 is 40% of 120
Answer: Kate = 40/3 Her father = 50
Step-by-step explanation:
Let Kate's age in the present be K
And Kate's father's age in the present be F
3(K+5) = F+5
6(K-6) = F-6
Rearrange the first equation to get
3K+15 = F+5
3K+10 = F
Substitute that into the second question
6K-36 = 3K+10-6
3K = 40
K = 40/3
So F = 3*40/3+10 = 50
Your x-intercept is at (-2,0) and your y intercept at (0,-3), so it's D
