Answer: x= 0.18779342
Step-by-step explanation:
From the first equation,
x+5 = 3(y+5)
x = 3y + 15 - 5
Now substitue x in the second equation with (3y +15 - 5).
x-5 = 7(y-5)
(3y+15-5) - 5 = 7(y-5)
3y +5 = 7y - 35
-4y = - 40
y = 10
Since y is 10, and x is (3y +15 - 5),
x = 30 + 15 - 5 = 40
The mean is -4 cause u have to add ale the numbers togeter
There would be 6 shapes, and it would depend on what those shapes are since you wouldn't know the measurements.
So what you would do is 8/5 + 4 x 7 = 26.9
then you round it to 30
