Answer:
(-8) + (+17) = -8 + 17 = 9
Step-by-step explanation:
Level of water in the first week = - 8 (the negative sign represents a decrease in inches, of the level of water)
Level of water during the second week = + 17 (the positive sign represents an increase, in inches, of the level of water).
These changes in the level of water can be modelled as sum of a positive and a negative integer as follows:
(-8) + (+17)
When adding a negative and a positive integer value, subtract the smaller value from the greater value, and retain the sign of the value that is greater.
17 is greater than 8. Therefore, subtract 8 from 17, and retain the sign of 17.
Thus:
(-8) + (+17) = -8 + 17
= 9
Answer:
0
Step-by-step explanation:
Here,
p=2
b=2
c=?
we know that,
c= p²-b²
=4-4
=0

Answer:</h3>
99.90%
<h3>
Step-by-step explanation:</h3>
STEPS:
- Find the total amount
- Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
- Turn into a percentage by multiplying by 100
Find the total sum
30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total
Find the fraction that small businesses make up of the total
Convert to percentage
0.9990 → % = 0.9990 × 100 = 99.90%

(11x2 + 2x3 + 14 +17x) ÷ (2x + 5)
= (2x^3 + 11x^2 + 17x + 14) ÷ (2x + 5)
= x^2 + 3x + 1 r 9
Answer:
The numbers are 63, 26, & 21
Step-by-step explanation:
110 = 3x + (5 + x) + x
105 = 3x + 2x
105 = 5x
21 = x
Plug it back into the first equation to find your values
