Answer:
The answer to your question is:
61.- 25
62.- 26
Step-by-step explanation:
61.-
2(5x + 5) + 2(2x) = 360
10x + 10 + 4x = 360
14x = 360 - 10
14x = 350
x = 350/14
x = 25
62.-
2(4x - 4) + 2(3x + 2) = 360
8x - 8 + 6x + 4 = 360
14x - 4 = 360
14x = 360 + 4
14x = 364
x = 364 / 14
x = 26
Answer:
0.555km p/h
shown as 555m p/h
Step-by-step explanation:
First we convert km to meters
6k = 6000m
Time = distance / rate.
20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr
then 3.33 / 6 = 0.555 km = 555 meters p/h
Step-by-step explanation:
what you did was you multiplied all numbers (incl. pi as number) :
1/6, pi, 1/12, pi
and that gives 0.137077839. no i or pi attached. just the plain result number.
so, if you need to just calculate the factors of pi, but don't need the fully numeric result, then your problem looks like
1/6 × pi × 1/12 × pi = 1/72 × pi²
so, you have an expression of pi² with a factor of 1/72.
you only need to type in all the factors, not pi itself (that's what you need to add at the end yourself).
Right triangle or equilateral(not sure if i spelled it right) triangle
