Answer:
6. The number is 
7. The two numbers are
and 
Step-by-step explanation:
Question six can be re-worded to create the following expression:

Solve for x to find the number:

Question seven can be solved by first listing the constraints (assuming x is smaller than y):
- x and y are less than 20


To get the numbers, we can create a system of linear equations. First, solve for
in each expression:


Solve for
:

Solve for
:

You know you need to rename a mixed number to subtract when the numbers involved have different denominators. In such a case. The lowest common multiple of the denominators will be calculated subsequent used to adequately rename the mixed numbers before subtraction can be done
Answer:
The first one is 0, the second one is ARN (All real numbers)
Step-by-step explanation:
1. Anything raised to the "zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.
<span>1st year value =45$
2nd year value=45+2.80$=47.80$
3rd year value=47.8+2.80$=50.60$
4th year value=50.60+2.80=53.40$
5th year value=53.40+2.80=56.20$
ater 5 years value of share becomes 56.20$
or
share after 5 years= 45+4*2.80=45+11.20=56.20$</span>
Answer:
48
Step-by-step explanation:
Signals during a multiplication of two numbers:
They have the same signal: The multiplication is positive.
They have different signals: The multiplication is negative.
3 times (-8) times (-2)
First 3*(-8):
Different signals, so negative. 3*8 = 24. So the answer is -24.
Then:
3*(-8)*(-2) = (-24)*(-2)
Same signal, so positive. 24*2 = 48. The answer is 48.
