Answer:
x = 3
Step-by-step explanation:
10 + 5x = 25
take 10 from both sides 5x = 15
divide both sides by 5 x = 3
Answer:
the third quartile is 8.......
15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4
4a + 11-a = 2
3a = 2-11
3a = -9
a = -3
7=7, 14, ,21, 28
3= 3, 6, 9, 12, 15, 18, 21, 24
So the LCM of 7 and 3 is 21.
