i hope u understand :)
108 minutes because 50 percent of 240 is 120 so take 5 percent away and it is 108
12(6) + 30(3)
= 72 + 90
= 162
Answer:
x = 10.
Step-by-step explanation:
8/12 = (x + 4)/(2x + 1) Simplify 8/12:
2/3 = (x + 4)/(2x + 1) Cross multiply:
2(2x + 1) = 3(x + 4)
4x + 2 = 3x + 12
x = 10.
