Answer:
A. 40%
Step-by-step explanation:
Model with an equation
50x = 20
Isolate x
x = 20/50
Simplify
x = 2/5
x = 0.4
Convert the decimal to a percentage (move decimal two places to the left)
0.4 = 40%
Answer:
Distance from Fresno where both cars meet = 210 - 150 = 60 miles
Step-by-step explanation:
let x = distance travelled by A from Sacramento
y = distance travelled by B from Los Angeles
t = time after 12 noon that they meet
x = 50(t + 1)
y = 400 - x = 75(t) or x = 400 - 75t
so: 50(t + 1) = 400 - 75t
50t + 50 = 400 - 75t
50t + 75t = 400 - 50
t = 2,8 hrs
so y = 400 - 75(2.8) = 210 miles from Los Angeles
distance from Fresno where both cars meet = 210 - 150 = 60 miles
Explanation:
<em><u>The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.</u></em>
