Answer:
problem e. : x = 30.48
problem f. : x = 328.1
Step-by-step explanation:
first off, i looked at the ratio of the numbers that did not include x. for example, the denominator on the right side of problem e. is 12x the number on the left side. so, i just multiplied the right numerator by 12. i did the exact same thing for problem f. , just opposite.
