(3/5n)(9)10=1/5n−23/10
27/50n=1/5n+−23/10
Subtract 1/5n from both sides.
27/50n−1/5n=1/5n+−23/10−1/5n
17/50n=−23/10
Multiply both sides by 50/17.
(50/17)*(17/50n)=(50/17)*(−23/10)
n=−115/17
Let x be the angle. The complement is 3x + 10. The sum of two complementary angles is 90. So,
x + 3x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Plug x into the complement
3(20) + 10 = 70
The angle is 20 degrees and the complement is 70 degrees
Here is the equation:
43.25 = 1.25t + 7 where t is the number of minutes he was on the trampoline.
If you're looking for Sam's age, the equation is 2x+5=3x-1. When solved, you get 6. Sam is 6.
