The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50

Answer:
(B) 1/27
Step-by-step explanation:
The terms of the sequence have a common ratio.
(1/8)/(3/16) = (2/16)/(3/16) = 2/3
(1/12)/(1/8) = (2/24)/(3/24) = 2/3
(1/18)/(1/12) = 12/18 = 2/3
The next term will be ...
(1/18)(2/3) = 2/54 = 1/27 . . . . matches choice B
you cant really predict how many bagels will be sold the next morning because of different scenarios but mathematically speaking if you compare plain bagels to total bagels you get 3/15 so if you multiply the denominator by 1 1/4 to get twenty as the denominator then you have to do the same to the numerator to get a fraction of 3.75/20 or roughly 3-4 plain bagels sold
2x+3
First, subtract “x” from “3x” to get 2x. Then, subtract 5-2. You should end up with an answer of 2x+3!
