Answer:
Step-by-step explanation:
Assumptions
You have to make some assumptions here without a diagram, and those assumptions can be wrong.
- The endpoints of <C at the same endpoints as the arc.
- The central angle is also 4x
- The measure of C is 1/2 the measure of the central angle.
With these in mind we can go on
Equation
- 2*<C = the measurement of the arc.
- 2*(x + 5) = 4x Properties of Arcs central angles and interior angles with the vertex and two other points on the legs of angle hitting the circumference.
Solution
Remove the brackets
- 2x + 10 = 4x Subtract 2x from both sides
- 2x - 2x + 10 = 4x - 2x
- 10 = 2x Divide both sides by 2
- 10/2 = 2x/2
- 5 = x Answer
We have x+5y=3 => x= 3-5y
So 3y+2=4x
<=>3y+2=4(3-5y)
<=>3y+2=12-20y
<=>3y+20y=12-2
<=>23y=10
<=>y=10/23 => x=3-5(10/23)=19/23
Ok done. Thank to me :>

Answer: Chris reached Boston at 10:24 a.m.
Explanation:
Since we have given that
Speed at which Chris ran from Newton to Boston = 15 km/h
Speed at which Goffy ran from Newton to Boston = 12 km/h
Time at which both started = 10:00 a.m.
Time at which Goffy reached Boston = 10:30 a.m.
That means Goffy takes half an hour to reach Boston,
so, Distance between Newton and Boston is given by
![Speed \times Time\\\\=12\times \frac{1}{2}=6 \ km](https://tex.z-dn.net/?f=Speed%20%5Ctimes%20Time%5C%5C%5C%5C%3D12%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%3D6%20%5C%20km)
So, Time taken by Chris to ran from Newton and Boston is given by
![Time=\frac{Distance}{Speed}=\frac{6}{15}=\frac{2}{5}\times 60\ minutes=24\ minutes\\](https://tex.z-dn.net/?f=Time%3D%5Cfrac%7BDistance%7D%7BSpeed%7D%3D%5Cfrac%7B6%7D%7B15%7D%3D%5Cfrac%7B2%7D%7B5%7D%5Ctimes%2060%5C%20minutes%3D24%5C%20minutes%5C%5C)
So, Chris reached Boston at 10:24 a.m.
