2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50

Answer:
length=72
width=63
Step-by-step explanation:
Let us start by supposing the following:
w=w
l=9+w
2l+2w=p(perimeter)
2(9+w)+2*w=270
2w+2w+18=270
4w+18=270
4w=252
w=63
l=72
We used the perimeter formula, 2l+2w=P(perimeter)
Answer:
300
Step-by-step explanation:
so the likelyhood of an incorrectly weighted job is 3/30 which, when simplified, is 1 in 10. you then extrapolate that data to 3000, and 3000/10 is 300.
