Answer:
Multiply the whole numbers by their denominators and then add the product to their numerators. You will notice that they equal the same improper fraction.
Step-by-step explanation:
4 * 6 = 24.
24 + 2 = 26.
4 2/6 as an improper fraction equals 26/6.
3 * 6 = 18.
18 + 8 = 26.
3 8/6 as in improper fraction equals 26/6 as well.
So that is how they are equivalent.

This is an awful question. They mean to say the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.
Inverse variation means the product is a constant, we'll call it k.
ht = k
When h = 1 hour t=6 minutes
(1)(6) = k
k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)
Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.
ht = k
h = k/t = 6/5 = 1.2 hours
Answer: 1.2 hours, second choice
Answer:
12
Step-by-step explanation:
4y - 2x
= 4(7) - 2(8)
= 28 - 16
= 12
