Answer:
you can get 360 miles on a full tank
Step-by-step explanation:
We'll have to add up all the fractions.
First, find the LCM of the denominators.
To do this, we'll use the listing method.
4: 4, 8, 12, 16, 20, 24, 28, 32, 36, all the way to 140.
5: 5, 10, 15, 20, 25, 30, 35, all the way to 140.
7: 7, 14, 21, 28, 35, 42, 49, all the way to 140.
So, 140 is the Least Common Multiple.
Multiply the numerator of 1 as many times you multiplied 4 to get to 140, which is 35.
1 x 35 = 35.
Multiply the numerator of 2 as many times you multiplied 5 to get to 140, which is 28.
2 x 28 = 56
Multiply the numerator of 3 as many times you multiplied 7 to get to 140, which is 20.
3 x 20 = 60.
So: 35/140 + 56/140 + 60/140
=35/140 + 116/140
=151/140
=1 11/140
So, the swimmer swam 1 and 11/140th of a mile.
Answer- 7n-6/2
Step by step explanation-
solution,
here
Given,
g(n)=2n+6/7
Let g(n) be y
So,
Interchanging the position of n and y we get the reverse So,
n = 2y+6/7
or, 7n = 2y+6
or, 7n-6 = 2y
or, 7n-6/2 = y
Therefore the inverse function of g(n) is 7n-6/2
Thank you.
Well in order to solve this we need to get the solution to each side.
(23+) +19 = 23 + ( +19)
23 + 19 23 + 19
= 42 = 42
So this means
each side equals 42
42 = 42
So this means there are infinite solutions
Good Luck! :)
Answer:
3x=5+2x would be the system of equations you would use. You have to take the number of bracelets made each hour (3x for Rachel and 2x for Oliver) and then remember to add the number of bracelets Oliver has already completed. The numbers represent the bracelets made, while the x (or whatever variable you choose to use) represents the hours spent. Then you solve for x, which ends up equaling 5. Therefore, after 5 hours, Rachel and Oliver will have the same number of bracelets.
