Best ResponseYou've already chosen the best response.0Craig wants to use an elevator to carry identical packages having the same weight. Each package weighs 4 pounds and Craig weighs 90 pounds. If the elevator can carry a maximum of 330 pounds at a time, which inequality shows the maximum number of packages, n, that Craig can carry with himself in the elevator if he is the only passenger? n ≥ 60 n ≤ 60 n ≤ 236 n ≥ 236

Best ResponseYou've already chosen the best response.1The maximum amount of weight allowed in the elevator is 330. This means that \[4x+90\le330\] Where x is the amount of packages. All you have to do is solve for x, and there's your answer!

Best ResponseYou've already chosen the best response.0hmm,,, (3/4)x  3 = 18 I guess I would add 3 to both sides first to get x by itself

Best ResponseYou've already chosen the best response.0Brent has two barcode printing machines. Each machine can print 25 barcodes per minute. On day 1, only the first machine was used, and it printed 95 barcodes. On the following day, the first machine printed for x minutes and the second machine printed for y minutes. Which expression shows the total number of barcodes printed by both machines during these two days? 95 + 25x + 25y 120x + 25y 25 + 95x + y 95x + 50y

Vocaloid

Best ResponseYou've already chosen the best response.0"consecutive" means three numbers that increase by 1 each time, so we have x x + 1 x + 1 + 1 add them together, and set them equal to 84 x + x + 1 + x + 1 + 1 = 84 first step is to solve for x

Vocaloid

Best ResponseYou've already chosen the best response.0well, ok, you solved the equation I gave you and got x = 27. this means we can replace "x" with "27" whenever we see x so, if x = 27, then x + 2 = ?

anonymous

Best ResponseYou've already chosen the best response.0oh so... 27 = 27 and 27 + 2

Vocaloid

Best ResponseYou've already chosen the best response.0yup, so x + 2 = 27 + 2 = 29, and 29 is your answer

Best ResponseYou've already chosen the best response.0Lara has violet and blue pansies in groups of 5. She has x groups of violet pansies and y groups of blue pansies. Which expression shows the total number of pansies that Lara has? 5x + y 5x + 5y x + 5y x over 5 + y over 5

Vocaloid

Best ResponseYou've already chosen the best response.0well, we'll use multiplication there are 5 pansies in 1 group of pansies, so there are 5x pansies in 5 groups of pansies
