You need to implement the process of "flip-flop" and multiply which is where you flip the second fraction and multiply.
÷
⇒
×
Now you multiply across. 2×15=30 and 3×11=33
So now it is

To reduce to the lowest terms, find the GCF common factor
The GCF is 3
Divide both the numerator and denominator by 3
÷
=
Answer:
Answer:
14 hours
Step-by-step explanation:
Let's call the task 3x
The older bro does twice as younger so it would be 2x long and younger brother work x long
Since the totsl of work is 3x = 21 x woul be 21÷3 = 7
the older brother must work 2 × 7 = 14 hours long
(sqrt7)^6x = 49x - 6
There is no easy way to solve this . Drawing a graph will give a good approximation.
Draw y = (sqrt7)66x
and y = 49x - 6 and see where they intersect
Ill draw it on desmos graphing tool and give you the link.
You are correct, it would be a reflection across the y-axis. I am great at visualizing but for those who are not (Not saying you) all they have to do is cut out a parallelogram and mimic the movements.
In the data set below, what are the lower quartile, the median, and the upper quartile. 13, 16, 16, 17, 51, 57, 62, 72, 92, 97

Answer:
I'm rusty on this but I believe:
the median is 54
the lower quartile = 16
the upper quartile is 72
