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
You are gonna use a^2 + b^2 = c^2 because the cities make a right triangle and you are trying to find the hypotenuse (c). C^2 ends up being 517 and the square root, your answer, is 22.7 miles
In decimal form that would be 36.052
<u>The answer is C</u>. This is because the square of 8 is 64 and the square of 9 is 81. The only number in between those choices is C; 71.
Hope this helps :)
(mind giving me brainliest answer? it helps!)
A = account
