Emmy learned to sing a total of 12 pieces over the course of 6 weeks of voice lessons. How many weeks of lessons will Emmy need before she will be able to sing a total of 14 pieces? Assume the relationship is directly proportional.

7 weeks.

Step-by-step explanation:

It took Emmy six weeks of vocal lesson to learn twelve pieces. If you divide 12÷6 it equals 2 or if you multiply 6×2 it equals 12, just like that if you divide (14÷7=2) or multiply (7×2) you will get the answer. you can also divide first and then multiply to check the answer/vice-versa.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
