1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..
I'll do the others in a different answer!!
Answer:
$1.65
Step-by-step explanation:
first i divided 0.99 by 3, equalling 0.33. i then multiplied 5 times 0.99 to equal 1.65.
75/100 = 0.75
--------------------
12 x 0.75 = 9
* The mine elevator travels a
distance of 9 metres per minute.
---------------------
After 2 minutes, the mine elevator
would've travelled 18 metres,
therefore your answer is:
A: -18 metres
Answer:
Negative, linear
Step-by-step explanation:
If you look at it, it is relatively in a line and the values are going down.
14^2 - 9^2 = a^2
Easy enough
14^2 = 196
9^2 = 81
196 - 81 = 115
The square root of 115 = 10.72
The third side is 10.72km
