Answer:
35
Step-by-step explanation:
Solving this ^^ would equal t=35.
Top:
x / (x + 1) - 1 / x
= [x^2 - (x +1)] / x(x+1)
= (x^2 - x - 1 ) / x (x+1)
Bottom:
x / (x + 1) + 1 / x
= [x^2 + (x +1)] / x(x+1)
= (x^2 + x + 1 ) / x (x+1)
Now you have:
(x^2 - x - 1 ) / x (x+1)
----------------------------
(x^2 + x + 1 ) / x (x+1)
= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )
= (x^2 - x - 1 ) /(x^2 + x + 1 )
Answer:
x^2 - x - 1
---------------------
x^2 + x + 1
2,100 quarts could be made in 12 hours. The rate for that day was 175 quarts every hour. We get this by dividing 350 by 2.
Answer:
1. TRUE
2. False
3. TRUE
4. False
5. TRUE
6. False
Step-by-step explanation:
1. 6859^(1/3) = 19 = ∛(19^3)
__
2. 2197^(1/3) = 13 ≠ 9·2
__
3. 8000^(1/3) = 20 = 10·2
__
4. 9261^(1/3) = 21 ≠ 13
__
5. 3375^(1/3) = 15 = 5·3
__
6. 5832^(1/3) = 18 ≠ 3·7
When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>
