(a) If

is the mass (in mg) remaining after

years, then


(b)

(c)
The easiest way to do this is with cross-multiplication.
4 gallons for 30 plants is written as 4/30
x gallons for 45 plants is written as x/45
Multiply 4 x 45 = 180
divide by 30
= 6 gallons of water
Answer:
X is grater than or equal to 6
Step-by-step explanation:
4x -5 > 2x + 17
+5 > 2x - 5
4x > 2x + 12

14 to 8 14/8 = (14 ÷ 2)/(8 ÷ 2) = 7/4 = 1 3/4
Your answer is 1 and 3/4
Given A = {1, 3, 5}, B = {2, 4, 6} and C={1, 2, 3, 4, 5, 6}, then A ∪ (B ∩ C)
Serggg [28]
B ∩ C is an intersection, which means only values that are present in both B and C are picked. So...
B ∩ C = {2, 4, 6}
A ∪ (B ∩ C) is a union, which means you combine all values, but discard duplicates. So...
A ∪ (B ∩ C) = {1, 2, 3, 4, 5, 6}
