20
Step-by-step explanation:
if you want to vary how many one can do in 5 hours you just have to subtract 5 from 100. need help just come to me
9.16x10^6 = 9160000
8.05x10^8 =805000000
805000000
- 9160000
__________
795840000
795840000 = 7.9584x10^8
Step-by-step explanation:
Each transversal crossing a line generates 2 pairs of vertical angles and for 3 transversal crossing the same line it will be 3 x2 = 6 pairs (or 12 angles)
5x + y = 15
y = -5x + 15
Substituting y= -5x+15 from first equation into second equation:
3x + 2y = 16
3x + 2·(-5x + 15) = 16
3x - 10x + 30 = 16
-7x + 30 = 16
7x = 30 - 16 = 14
x = 2
Substituting x=2 into the first equation:
5x + y = 15
5(2) + y = 15
10 + y = 15
y = 15 - 10
y = 5
So your final answers are x=2 and y=5.
