(1/2)*x - (3/10)*x = 200
(5/10)*x - (3/10)*x = 200
(2/10)*x = 200
(1/5)*x = 200
x = 200*(5/1)
x = 200*5
x = 1,000 pennies

Consider a sequence whose first three
snow_tiger [21]

Answer:

Below, depends if 27 is term number 1 or term number 0.  Answered for both cases.  

Step-by-step explanation:

The most common sequences are arithmetic and geometric, so lets check those first.

Arithmetic first since its the easiest.

to go from 27 to 21 we subtract 6, if we subtract 6 from 21 again we get to 15, which is what we need, so it is indeed arithmetic.

Explicit formula is basically of the form of y=mx+b with an arithmetic sequence.  the m is the common difference and b is the first term minus the common difference.  so lets fill those in.  y = -6x + 33

Then it usually has n as the x and y f(n) so we'll just put those in

f(n) = -6n + 33

This si as long as the first term is labeled as term number 1 and not term number 0.  if you have 27 as term 0 instead just make 33 back to 27, so f(n) = -6n + 27

Let me know if this doesn't make sense.

The width of a rectangle is 6 less than half the length. If x represents the length, which equation could be used to find the wi
Shtirlitz [24]

Answer:

C. y=1/2x-6

Step-by-step explanation:

The correct answer is C. y=1/2x-6.

If we are finding 1/2 of the length, and the length is represented by x, than we would have 1/2x.

It also says 6 less than halve of the length, so we would represent that as 1/2x-6, and that shows us the proper equation to find the width.

Hope this helps!

I really need help with this question <br> n+5≤16
ahrayia [7]

Answer:

the answer would be anything 11 and under (11,10,9,8,7,6,5,4,3,2,1,0)

Step-by-step explanation:

This is because if n+5 is less than or equal to 16 then 11+5=16 so that is equal to and less than would be using any number less than 11

hope this helps ;)
