Is it inequality? If so, 5n<65 so n<13
The answers 10 because you add them all together then multiple 5 by 2
Answer:
in decimal form (rounding to four decimal places) 4.6667
in fraction form 14/3
Step-by-step explanation:
(2/3)7
Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y
Set up a system of equations and use substitution
x + y = 2.75
x + 7y = 11.75
x + y = 2.75 can be rewritten as y = -x + 2.75
x + 7 (-x + 2.75) = 11.25
-6x + 19.25 = 11.25
-6x = -8
x = .75
plug x back into other equation to find y
y = -.75 + 2.75
y = 2.00
1 hot dog = $0.75
1 hamburger = $2.00
834.76 to the nearest one is 835.00
