In my opinion the concepts that belong in the branch of mathematics would be algebra, geometry, trigonometry, calculus, statistics, and probability. All of the following are known the be main branches of pure mathematics.
Answer:
y < - 12
Step-by-step explanation:
y + 15 < 3 ( subtract 15 from both sides )
y < - 12
So the answers 3,000 cause it said period i mean unit period
Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
Let us assume the capacity of the gas tank = x gallons
Then
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
= 20 gallons
So the total capacity of the gas tank of the car is 20 gallons. I hope the procedure is clear to you.
(2x-5)(3x-1)=0
2x-5 = 0 or 3x-1= 0
2x = 5 3x = 1
x = 5/2 x = 1/3
Answer: x=5/2; x=1/3
