Answer:
21
Step-by-step explanation:
The x intercept is represented by the coordinate (x,0) on x axis.
So, to find the x intercept ,we need to equate y=0 in the equation 20x+70y=420
=> 20x+ 70*0=420
=> x=420/20 =21.
x intercept is (21,0).
Answer:
21
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
20*X+70*Y-420=0
Pull out like factors :
20x + 70y - 420 = 10 • (2x + 7y - 42)
Equation of a straight line:
y=mx+b
2x+7y-42 = 0
y-intercept = 42/7 = 6
x-intercept = 42/2 = 21

Answer: 22.55 mph
Step-by-step explanation:
Let the speed of the train be n
4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours
11 × n = 248
11n = 248
n = 248/11
n = 22.55mph
