Set up a system of equations and say green route is x and blue route is y
This will give you
Monday 6x + 5y= 52
Tuesday 12x + 13y = 119
Solve by multiplying the top equation by two to get
12x + 10y= 104
Since you have 12x in both equations, these cancel out when you subtract the bottom from the top. This leaves you with
-3y=-15
Y=5
The blue route is 5 miles, but they want to know the green route. Fill in the y value in either one of your equations. Let’s use the one from Tuesday
12x + 13 (5) = 119
12x= 54
X= 4.5
This means that the answer is 4.5 miles
You basically just switch it around and subtract the fractions
Answer:
.
Step-by-step explanation:
The value of x° is 22° and exterior angle is 25.
Step-by-step explanation:
l can prove like this,
Here,2x°+(103-x)°=(6x-7)°...Being exterior angle
or,2x°+103°-x°=6x°-7°
or,x°+103°=6x°-7°
or,103°+7°=6x°-7°
or,5x°=110°
or,x°=110°÷5=22°
Now,
x°=22°
(6x-7)°=(6×22-7)°=125°
