I would set the equations on top of each other and subtract
6x+y=21
- 3x-y=6
________
3x=15
Then solve for x
X=5
To solve for y, plug 5 in for x for one of the equations
Answer:
you would just 4.8 x how many years
Step-by-step explanation:
The value of each is what u said there right
diagonal = sqrt(l^ + w^2)
17 = sqrt(10^2 + x^2)
17^2 = 10^2 + x^2
289 = 100 + x^2
189 = x^2
x = sqrt(189) = 13.747
X = 13.75
width is 13.75 inches
