Answer:
3
Step-by-step explanation:
56/4 = 14
42/14= 3
so he/she can fit 3 tires in 42 minutes
The rate of how many projects Taylor can complete can be modeled at x/6 and Brianne can be modelled as x/8. So, by combining the functions and setting equal to 1, you can solve.
x/6 + x/8 = 1
You have to give common demoninators
4x/24 + 3x/24 = 1
Then add together and cross multiply. Giving you an answer of 24/7 or roughly 3.43 hours when rounded to the nearest hundredth.
Yes, any number that you can divide 72 by without creating an irrational number answer is a factor of 72. Therefore, since when we divide 72 by 2, we get 36, which is a whole number and therefore satisfies the criteria.
Answer:
The number is 5
Step-by-step explanation:
First of all we have to convert the given scenario in mathematical or algebraic expression.
Let x be the number
Then according to given statement, the equation will be:
"Three times a certain number"
"is added to 5"
"the result is 20"
Using Subtraction property of Equality
Using division property of equality
Hence,
The number is 5
