12 = 3/4 * x
12 ÷ 3/4 = x
12 * 4/3 = x
48/3 = x
16 = x
Answer: The whole set is 16 counters
150 + 20x, where x is the number of cellphones sold
-1/5of 15 =-3 then add 3 2/5th which is 17/2 so -3+17/2 = 11/2=5 1/2
Answer:
Step-by-step explanation:
x^2 + 3x - 10 = 0
(x - 2)(x + 5) = 0
x - 2 = 0 x + 5 = 0
x = 2 x = -5
smaller x = -5
larger x = 2
