The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
Hey there!
We can set up an equation. Since 20% is said as twenty percent, we can conclude that it says "per-cent", which means "per hundred", like century is a hundred years. That way, we can say that 20% is also written as a decimal of twenty hundredths, because it's per hundred. Thus, we're saying that his down payment, 1,600, is (this is keywording for equals) 20% of (keyword for multiplication) the total price (x). That gives us:
1,600 = .20x
Divide both sides by .20
x = 8,000
Therefore, the cost of the car was 8,000 dollars.
