Answer:
b=7
Step-by-step explanation:
2(3b-1)= 40
divide both sides by 2
3b-1 = 20
then add 1 to each side
3b = 21
then divide both sides by 3
b = 7
then check 2(3*7-1) = 40
Answer:
-8
Step-by-step explanation:
x^(m/n)=![\sqrt[n]{x}^m](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%5Em)
(-32)^(3/5)
=![\sqrt[5]{(-32)} ^3](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%28-32%29%7D%20%5E3)
=(-2)^3
=-8
Answer:
22 AUD × (1 USD)/(1.2 AUD)
Step-by-step explanation:
1.2 AUD = 1 USD
Divide both sides by 1.2 AUD.
(1.2 AUD)/(1.2 AUD) = (1 USD)/(1.2 AUD)
(1 USD)/(1.2 AUD) = 1
The conversion factor from AUD to USD is (1 USD)/(1.2 AUD)
Answer: 22 AUD × (1 USD)/(1.2 AUD)
1 pound = 16 ounces
If you have 6 pounds of horsehair,
16 ounces × 6 pounds = 96 ounces
One pull weights about 0.011 ounces, in order to find how many pulls you can make with 96 ounces of horsehair, you divide 96 ÷ 0.011 .
96 ÷ 0.011 = 8727 (rounded to whole number)
8727 pulls could be made from 6 pounds of horsehair.
