Let's move all to one side:
6r+7-13-7r=0
and re-arrange to have similar terms together:
6r-7r +7-13=0
let's add up what we can:
-1r-6=0
we can move the -6 to the other side and multiply both sides by -1 and we get:
r=-6 This is the<em> solution. </em>
Answer:
Ok since i don't know the measurements I'm just gonna tell you what to do
Step-by-step explanation:
First multiply the angle of the triangle that is twice as large the other by 2 then add 5 to the answer that you you got from multiplying the other triangle by 2 and you should have your answers. I hope you understand
To find that subtract Jane's own from Joe's so
2/5-1/7=9/35

Answer:
6852 feet .
Step-by-step explanation:
Refer the attached figure
The chairlift at a ski resort rises a total of 2600 feet from where it starts. i.e.AB = 2600 feet
The angle of elevation is about 22.3 degrees.i.e.∠ACB= 22.3°
We are supposed to find How far do riders travel on the lift i.e.AC
In ΔABC
We will use trigonometric ratio





So, riders travel 6852 feet .
