Answer:
15, 17, 19
Step-by-step explanation:
x + x+2 + x+4 = 15 + (x+2 + x+4)
3x + 6 = 15 + 2x + 21
x = 15
x+2 = 17
x+4 = 19
500 dots: this is because 1 minute is 5 dots. So, 5×100=500!
Answer:
x = -11/4
Step-by-step explanation:
Given that:
-2 = 5 / (2x+3)
Multiplying both sides by (2x + 3)
-2(2x + 3) = 5
"-" sign will alter the inner signs
-4x -6 = 5
Adding 6 on both sides:
-4x -6 +6 = 5 + 6
-4x = 11
Dividing both sides by -4
-4x/-4 = 11/-4
x = -11/4
