Answer:
256 Coins
Step-by-step explanation:
On the first day, Jada starts with one coin, so all you have to do here is multiply it by 2.
Day 1: 2 coins
Day 2: 2 x 2 = 4 coins
Day 3: 4 x 2 = 8 coins
Day 4: 8 x 2 = 16 coins
Day 5: 16 x 2 = 32 coins
Day 6: 32 x 2 = 64 coins
Day 7: 64 x 2 = 128 coins
Day 8: 128 x 2 = 256 coins

Answer:
Emily has 20 students and Santiago has 18 students in home rooms
Step-by-step explanation:
to figure out the number in Emily's class we need to answer this question - '15 is 75% of what number'?
we can use:
is/of = %/100
is = 15
of = 'n'
75% = 75/100 or 3/4
15/n = 3/4
cross-multiply to get:
3n = 60
n = 20
So there are 20 students in Emily's home room
Now we find the number of students in Santiago's home room:
the question is - '12 is 2/3 of what number'?
we can write this equation:
12 = 2/3n
multiply each side by 3/2 to get:
36/2 = n
18 = n
18 students in Santiago's home room
Sadly, the answer to your question is 'No'. The work written under
the problem on the paper is not correct ... because you tried to do
too much !
You can't combine 'm' terms with 'n' terms or with plain numbers.
They all need to stay separate all the way to the end.
So, actually, your first written line is the answer . . . <em>7m - 35 + 3n</em>
That's as far as you can go. You can't combine these terms. Stop there !
