There are 45 students in a class. The teacher wants to have groups with 5 students in each group. How many groups can the teacher make?

Inactive

The teacher can make 9 groups. We solve using: 45 students / (5 students / group) = 9 groups

Question:

Define and give a detailed example of intrasexual selection. How will this affect the phenotypes of subsequent generations?

Intrasexual selection is competition between members of the same sex for mates. Usually this involves males competing for females. One example of intrasexual selection is the selection for large antlers in male deer. Large, strong antlers allow male deer to compete with rivals for access to females. Males with larger and stronger antlers are more likely to defeat males with stronger and weaker antlers. The males with the large, strong antlers can win the competition and gain access to female mates. Over time, if males with the largest, strongest antlers are superior in competition and gain more female mates, these males will produce more offspring. Subsequent generations will have males with increasingly larger, stronger antlers due to intrasexual selection for this phenotype.

Question:

4x + 6 = 7x – 3. Find x.

We start by using subtraction to move like terms to the same side of the equation as each other but opposite side of the equation from unlike terms. Subtract 7x from both sides of the equation and subtract 6 from both sides of the equation: 4x + 6 - 7x - 6 = 7x - 3 - 7x - 6 On the left side, the + 6 and the - 6 cancel (add to 0). On the right side, the 7x and the - 7x add to 0 and we are left with: 4x - 7x = -3 - 6 which simplifies to: -3x = -9 Divide both sides of the equation by the coefficient of x, -3, to simplify. x = 3
