Answer:
9
Step-by-step explanation:
Let the no be x
By the conditions given ,
2x + 6x = 72
8x = 72
x = 72/8
x = 9
therefore the no is 9
1 1/2 divided by 1 1/6 equals 1.28571429
Rounded: 1.28, 1.29, or 1.30 (depends on what they ask for)
3/4 divided by 1 3/8 equals 0.54545455
Rounded: 0.54 or 0.55
98.07. its a longer number but thats it for short.
Answer:
x=5
Step-by-step explanation:
-3x+7=-8
Bring 7 to the other side, it becomes negative
-3x=-8-7
Signs are same on rhs so u add
-3x = -8+-7= -15
Bring -3 to the other side n divide
therefore,
x=-15/-3
= +5 (two negatives become positive)
Hope it helps!
