If you write a number over another number, it's called a FRACTION
Answer:
4x+(-3y)
Step-by-step explanation:

- (-)(-)=(+)
- (+)(-)=(-)
- (-)(+)=(-)
- (+)(+)=(+)

Eight decreased by six times the number k
The difference of eight and the product of six and the number k
Eight minus six times k
Six multiplied to k is less than 8
Answer:
<em>Step-by-step explanation:</em>
<em>Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56
</em>
<em>The idea is to estimate the proportion p = m/N of tagged =102.
</em>
<em>Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.
</em>
<em>It is reasonable that, k/n would be a good estimante for p = m/N.
</em>
<em>Accordingly, for an estimate N of N, se solve the equation m/N= k/n.
