Let the length of the 1st line segment = x
then the length of the second line segment = 4x + 5
The difference in their lengths = 35
so 4x + 5 - x = 35 ... [longer - shorter = 35]
3x = 30
x = 10
so the shorter (1st) line segment is 10 cm long
and the longer (2nd) line segment is 4 * 10 + 5 = 45 cm long
Answer:
5
Step-by-step explanation:
<em>35/7=5 </em>
Answer:
To find the intercepts, equate one variable to
0
and solve for the other variable:
y-intercept
Set
x
to
0
and solve for
y
giving:
3
x

5
y
=
15
becomes:
(

)
−

Next. we can plot the two points on the grid:
graph{((x-5)^2+(y)^2-0.125)((x)^2+(y+3)^2-0.125)=0 [-20, 20, -10, 10]}
Then, draw a line through the two points:
graph{(3x - 5y -15)((x-5)^2+(y)^2-0.125)((x)^2+(y+3)^2-0.125)=0 [-20, 20, -10, 10]}
50 cars per hour
To calculate the hourly rate divide 400 by 8
hourly rate = 
= 50 cars per hour
