Answer:
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
Answer : x = 40
move the constant to the right it changes to
3/4x = 23 + 7
then u add the numbers
23 + 7 = 30
3/4x = 30
after that u multiply both sides by 4/3
and you’ll get x = 40
Answer:
$92
Step-by-step explanation:
First, you need to divide the expense between the 5 nights. So 410/5=82. This is still with the coupon though. You need to add 10. When you do, you get $92/night. So, for five nights without the coupon, he would have spent $460 for the entire trip. Hope this Helps!
