Answer:
y = ¼(x-4)
Step-by-step explanation:
Before solving the question, let's look at one example,
- A is directly proportional to B means A∝B which also means A=kB where k is a constant.
In this case, y is directly proportional to (x-4) means that y∝(x-4) which can also mean that y=k(x-4).
Hence, to find the value of k, substitute x=16, y=3 into y=k(x-4),
3=k(16-4)
k=3/12
k=1/4
After that, substitute the k value into the equation,
<h3>y = ¼(x-4)</h3>
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
36 inches=2 feet
72 inches= 4 feet
1/84
1/7 ÷ 12
turn 12 into 1/12 bc your dividing fractions and turn the division symbol to multiplication
1/7 × 1/12
answer: 1/84
