2x + 100 = 5x + 55
3x = 45
x = 15
2(15) + 100 = 130
180-130 = 50
so angle 2 is 50 degrees
The answer is 21 + 4x.
You find this answer by adding up all the sides.
9+12+4x= 21+4x ... you don't add 4x because it has a variable that we do not know of the value.
B) it would make more since because it how far you and how much time you meet again at the starting line
X / 6=3.5 would be the answer
1kg = 1000g
4 apples = 1000g
1 apple = 1000/4
1 apple = 250g
