Answer: 8.2×10-3^1, I think the second part of the answer is 4.4×10^1 (44)
I think this is right but I'm not a mathematician.
Step-by-step explanation:
The first problem is 7.9×10^1 (79)
Second problem 4.6×10^1 (46)
Third problem 3.5×10^1 (35)
A(1) = - 3 ;
a(2) = a(1) + ( 2 - 1 )d ;
3 = -3 + d ;
d = 6 ;
a(3) = a(1) + ( 3 - 1)d;
9 = - 3 + 2d ;
12 = 2d ;
d = 6 ;
a(4) = a(1) + ( 4 - 1 )d ;
15 = -3 + 3d ;
18 = 3d ;
d = 6 ;
Then, a(n) = - 3 + ( n- 1 )6 ;
a(n) = - 3 + 6n - 6 ;
a(n) = 6n - 9 is an explicit functin rule for the sequence -3, 3, 9, 15, ...
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:
16 3/4 miles
Step-by-step explanation:
So the goal of this problem is to get Ryan's total driving distance which was made up of:
A 5 3/4 mile trip
A 6 1/2 mile trip
A 4 1/2 mile trip
Start by adding the last two since they have the same denominator
6 1/2 + 4 1/2 = 10 2/2 = 11
11 miles plus 5 3/4 miles
11 + 5 3/4 = 16 3/4
He drove at total of 16 3/4 miles
