Answer: the awnser to this problem is 38.5 sq. units
Step-by-step explanation:
The ordered pair which is a solution to the given inequality is: C. (2, 1).
<h3>What is an inequality?</h3>
An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:
- Less than (<).
- Greater than (>).
- Less than or equal to (≤).
- Greater than or equal to (≥).
Next, we would test the ordered pair with the given inequality to determine a solution as follows:
For ordered pair (4, 4), we have:
3x + 2y < 15
3(4) + 2(4) < 15
12 + 8 < 15
20 < 15 (False).
For ordered pair (3, 3), we have:
3x + 2y < 15
3(3) + 2(3) < 15
9 + 6 < 15
15 < 15 (False).
7x - 4y > 9
7(3) - 4(3) > 9
21 - 12 > 9
9 > 9 (False)
For ordered pair (2, 1), we have:
3x + 2y < 15
3(2) + 2(1) < 15
6 + 2 < 15
8 < 15 (True).
7x - 4y > 9
7(2) - 4(1) > 9
14 - 4 > 9
10 > 9 (True)
For ordered pair (1, 0), we have:
3x + 2y < 15
3(1) + 2(0) < 15
3 + 0 < 15
3 < 15 (True).
7x - 4y > 9
7(1) - 4(0) > 9
7 - 4 > 9
3 > 9 (False)

Answer: 1/20 (fraction) or 0.05 (decimal)
Step-by-step explanation:
first i like to make them a decimal so its easier.
1/4 = 0.25
1/5 = 0.2
multiply 0.25 and 0.2 = 0.05
make 0.05 a fraction
1/20
simplify. (it's already in its simplest form)
the answer is 1/20 as a fraction or 0.05 as a decimal.
(i dont know which one ur teacher wants u to do fraction or decimal?)
The answer to this question is 39.28; 65.12
Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)
15 = 5 + 8d - 12
15 = 8d - 7
<u>+7 + 7</u>
22 = 8d
22/8 = d
2.75 = d
Check:
15 = 5 + 4(2(2.75) - 3)
