Answer 1

Dale should use the $15 dollars off coupon to save the most money which costs 47.00.

25% off of 47.00 is 45.49.

$15 off of 47.00 is 32.00.

The $15 off coupon makes the DVD player cost less, so he should use that one.

Compare -8.9 and -9.3.

A.
-8.9 = -9.3

B.
-8.9 > -9.3

C.
-8.9 < -9.3

Answers

A number line will be helpful to compare the two of the given terms. The correct option is B, -8.9 > -9.3.

What is a number line?

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The two of the given numbers can be compared as shown below.

-8.9 > -9.3

This is because on a number line, numbers on left are of less value than numbers on the right. And since -8.9 is close to 0, then -9.3.

Hence, the correct option is B, -8.9 > -9.3.

2 3/4 - 5 1/8

Answers

2 3/4 - 5 1/8
simplified : 11/4 - 41/8
create a common denominator : 11/4x8 is 88/32 and 41/8x4 is 328/32
simplified : 88/32 - 328/32
simplified : 11/4 - 41/4 (divide both of the fractions by 8)
11/4 - 41/4 is -30/4
the answer is -30/4 or -7 2/4 or -7 1/2

Answer is -2 3/8

Step by step

To add or subtract fractions, the denominator (bottom) has to be the same, so you are working with the same fractional part of the whole.

- 5 1/8
2 6/8 (3/4 same as 6/8)
—————-

Change to improper fractions
- 5 1/8 = -41/8
2 6/8 = 22/8
————————-
subtract
-41/8
22/8
—————
-19/8

Simplify

-2 3/8

- 2 3/8 is your answer
