a set of equations is given below:

equation e: a = 5b + 1
equation f: a = 3b + 4

which statement describes a step that can be used to find the solution to the set of equations? (1 point)

equation f can be written as 5b + 1 = 3b + 4.

equation f can be written as b + 1 = 3b + 4.

equation f can be written as a = 3(a – 1) + 4.

equation f can be written as a = 5(a – 4) + 1.

What graph correctly matches the equation y equals two negative x

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
