Answer:
x=1
Step-by-step explanation:
For algebra always start by rewriting it.
4+x+2-2x=5
Then ask yourself is there any like terms we can combine, and here yes there is. 4 and 2 and x and -2x. Now lets combine them and rewrite.
6-x=5
Now lets get x alone and the quickest way is to subtract 6 to the other side
6-x=5
-6 -6
-x=-1
Now the two negatives cancel out as you would divide both sides by the coefficient -1 to get positive x alone. We can make this easier by just canceling out the negatives.
Your answer is
x=1
Answer:
straight line add up to 180 so subtract 42 from 180 thts ur answer
Answer:
option 2
Step-by-step explanation:
So let's say that the second angle is x.
Then we can say that the third angle is 
.
So then we have three angles:
1) 66°
2) x°
3) ()°
So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:
So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:
So the values of the angles are:
1) 66°
2) 38°
3) 76°
(9.69 ¢/km)*(7580 km) = 73450.2 ¢ = $734.50
