1,8 is the mid point of these two numbers
let Leo's speed = x mile/hr
so Ethan speed = (x + 6) miles per hour
Distance = Speed × Time
so distance traveled by Leo in 2 hours = x × 2 = 2x
and distance traveled by Ethan in 1.5 hours = 1.5( x + 6 ) = 1.5x + 9
since they meet on the path , After Ethan has ridden 1.5 hours and Leo has ridden 2 hours , so together the have traveled on complete path that is 65 miles.
⇒ distance traveled by leo in 2 hours + distance traveled by Ethan in 1.5 hours = 65
⇒ 2x + 1.5x + 9 = 65
⇒ 3.5x = 56
⇒ x = 16
Hence Leo's speed = x miles/hr = 16 miles/hour
and Ethan's speed = (x + 6) miles/hr = 16 +6 = 22 mile/hour
The answer is true. Proportionality means “having a constant ratio to another quantity”
Answer:
98.9
Step-by-step explanation:
Reminder: You can't just plot one dot, i meant do that like two times, then draw a line through it. This way you can shown the point of intersection.
1st Problem:<em> Plot a dot at -4 on the y-axis, then go down two and right one and plot another dot. Then for the second equation, add 4 to both sides. then you will come out with y= -4x+2. then with this, go ahead and plot a dot at positive 2, and go down four and to the right one. if you are trying to find the point of intersection, then it would be (2, -8).</em>
2nd Problem: <em>Plot a dot at -2 on the y-axis, hen go down three, and to the right 2 and plot a dot. Then for the second equation, plot a dot at positive 3, and go down 1 and to the right 4. </em>
3rd Problem: <em>Plot a dot on the y-axis at -5, then you are going to draw a straight line going across. The for the second equation, plot a dot at positive 1 on the y-axis, then go down three, to the right one. </em>
