Answer:
A. coefficients: 70, 12; variables: x, y.
B. 2 terms: 70x, 12y; separated by an addition symbol
C. 70x
Step-by-step explanation:
We will answer the questions in the context of this problem. In other problems, the meaning of "coefficient", "variable", and "term" may be different.
__
A. The coefficients are the numbers; the variables are the letters. Then the coefficients are 70 and 12; the variables are x and y.
__
B. Each product is a term. Terms are separated by the + sign. There are two terms in this expression, one on either side of the + sign. When an expression is written with no parentheses, the terms are separated by + or - signs. (Often, we think of the minus sign as being part of the coefficient of the term. Then we can say terms are separated by + signs. 10x + (-32y), for example.)
__
C. When you match the coefficients to the numbers in the problem statement, you see that the number matching the earnings at the diner is $70 per shift. If we assume that x represents the number of shifts worked at the diner, then the term 70x will represent the total earned from the diner. It is the product of the earnings per shift and the number of shifts.

Answer:
Part A
Each time you press F9 on your keyboard, you see an alternate life for Jacob, with his status for each age range shown as
either alive or dead. If the dead were first to appear for the age range of 75 to 76, for example, this would mean that Jacob
died between the ages of 75 and 76, or that he lived to be 75 years old.
Press F9 on your keyboard five times and see how long lacab lives in each of his alternate lives. How long did lacob live each
time?
