The value of x is 10
You do 3x-3 = 2x+13
Subtract 2x from both sides
x-3 = 13
add 3 to both sides
x=10
Answer:
Part a) The elevation of the road is
Part b) The rise is
Step-by-step explanation:
Part a) What is the elevation of the road to the nearest degree?
Let
y-----> the rise of the road ( vertical distance)
x ----> the run of the road (horizontal distance)
we have
y/x=1/10
we know that
The ratio y/x is equal to the tangent of the angle of the elevation of the road
Let
----> angle of the elevation of the road
Part b) If the road is two km long, how much does it rise?
using proportion
Step-by-step explanation:
Use this sort of layout, but where x will be an odd number, do not shade it. there should be a pattern of shaded segments followed by unshaded segments repeating
Answer:
9. B: y = 7.5x - 2
10. y = 2x - 1/4
11. C: A newborn baby weighs 8 pounds at birth and gains 1.5 pounds for 3 months.
