Answer:
The additive property of 0; any number added with 0 is going to be that number.
Step-by-step explanation:
6y - 8 ≤ 10 Add 8 to both sides
6y ≤ 18 Divide both sides by 6
y ≤ 3
Y is less than or equal to 3.
Yes, I believe they are equivalent because if you were to solve -1/4(10t-15) it would equal -2t+3
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
