Answer:
1. 88 - b
Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.
2. 73 + d
Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.
3. 23 x g
Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.
Answer:

H31 = -0.2
Step-by-step explanation:
The matrix sum H is the element-by-element sum of corresponding elements of F and G. For example, H31 = F31 +G31 = -4.7 +4.5 = -0.2.

For repetitive calculations using the same formula, it is convenient to do them using a spreadsheet.
Answer:
D) (10,22)
Step-by-step explanation:
based on given slope and point, the linear equation is <em>y = 9/5x + 2</em>
plugging in x-and-y values only results in a true statement for option D
example:
22 = 9/5(10) + 2
Does 22 = 18 + 2? Yes
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

Solving,

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

A little arithmetic shows that
