Answer:
21
Step-by-step explanation: 10+10+1=21
<span>Use formula: (a-b)</span>² = a² - 2ab + b²<span>
(r-1)</span>² = r² - 2r + 1
Answer:
b = - 14
Step-by-step explanation:
Given
- 
(8 + 5b) = 75 + 
b
Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions
- 5(8 + 5b) = 450 + 10b ← distribute left side
- 40 - 25b = 450 + 10b ( subtract 10b from both sides )
- 40 - 35b = 450 ( add 40 to both sides )
- 35b = 490 ( divide both sides by - 35 )
b = - 14
Answer:
1. n=10
2. n=35
3. n=6
4. n=0 ? not sure for this one. two variables in the proportion
5. n=36
Step-by-step explanation:
set each set of proportion equal to each other and do cross multiplication
hope this helps !
how are you ?
Answer:
To answer the question, more information is needed. For instance, if you know the amount of trail mix in each bag. But, to find an average, you first add up all the numbers (the amount of trail mix in each bag). Then divide the sum by the number of numbers (the amount of bags).
