He is not correct. If this is to be an equilateral triangle then all the angles must be the same measure. That means that 180/3 = 60°. They all have to equal 60°. If one of the angles measures 4x-12, then 4x-12=60. Solving for x, we will add 12 to both sides to get 4x=72. x here is 18. For the other angle measuring 2x+26, we would do the same. 2x+26=60. Subtract 26 from both sides to get 2x= 34 and x = 17. He was way off.
Answer:
440
Step-by-step explanation:
1.5 hours he 90 minutes
660/ 90=7.333
7.333*60 (which is how many minutes in an hour = 440 miles
Answer:
-y=-x
The problem:
y=x then -y=?
Step-by-step explanation:
If y=x, then -y=-x.
Just like if u=9, then -u=-9.
Or, if -m=8, then m=-8.
Linear because the x are not repeating
AN EXAMPLE OF NON LINEAR”0,1,2,2,” AN EXAMPLE OF LINEAR”0,1,2,3” the non linear the x repeat so the answer is linear
