Let the speed of the slower car = X
The speed of the faster car would be X + 15
They both traveled 3 hours and went 315 miles
Set up an equation:
3x + 3(x+15) = 315
Now solve for x:
3x + 3x +45 = 315
Simplify:
6x + 45 = 315
Subtract 45 from both sides:
6x = 270
Divide both sides by 6:
x = 270/6
x = 45
The slower car was doing 45 miles per hour.
The faster car was doing 60 miles per hour.
Vertical angles are made by two intersecting lines .and they are always equal
<span>∠C and ∠D are equal.
so </span><span>−x+26 =2x-10
-3x=-36
x=36/3
x=12</span>°
∠D= 2x-10
put value of x here
∠D=24-10
∠D=14°
Answer:
4.8
Step-by-step explanation:
I'm not really sure but you devide it and I got 4.80 and so the 0 doesn't help so I just get rid of it
