Answer:
5:15 simplified as 1:3
Step-by-step explanation:
The slope of the red line would be 5 as well as long as the lines are parallel. If it were perpendicular, or made an x, then the slope would be (1/5)<span />
Stool = s, chair = c
6s+4c=58 ---(1)
5s+2c=35 ---(2)
(2)*2; 10s+4c=70 ---(3)
(3)-(1); 4s=12
so s=3
from (2)
5s+2c= 35
5(3)+2c=35
2c = 35-15
2c = 20
so c=10
then the cost of each stool is $3 and the cost of each chair is $10
Speed is determined as distance travelled over time. In the
problem, given is the speed and distance. Time, we will be distance over speed.
Substitute the given to the formula
t=d/s
t = 200 km / 35.27 km/h
t = 5.67 hours
