10. During the hockey season, Elena
Debora [2.8K]

Answer:

Step-by-step explanation:

If I remember expanded form is putting all number in terms of being times 10 to a power.  starting with the ones place it's x10^0 which of course is just 1, so you don't need to include the x10 at all.

now, moving one either way  that 0 either  get 1 added to it or subtracted.  So in the 10s place it becomes x10^1 and the tenths place becomes x10^-1.  Similarly the hundreds place and hundreths place will have x10^2 and x10^-2 respectively.  So keep this pattern going to find each place of the number.  Can you list out what places are displayed in 5.625?

I will get you started, but let me know if you don't quite get it.  

5 + 6*10^-1 + ...

Can you figure out the rest?

grandymaker [24]

Answer:

Step-by-step explanation:

This is if the mortgage is annual also.

add all 3 which would equal 1,616.6.

But "why?" you ask is it so expensive.

it is still annual so divide it by 12 and you have 134.72

Which equation matches the statement below?
kvasek [131]

Answer:

3(n-5)=2n+16

Step-by-step explanation:

3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)

3(5 - n)

16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have

2n + 16

if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.

3(n-5) = 2n+16
