The sum is 160/(1-r)=1280 where r is the common ratio,
1/(1-r)=1280/160=8
Inverting we get 1-r=1/8, r=7/8.

grin007 [14]

Answer:

d(x) = 175 - |175 - 25x|

Step-by-step explanation:

Suppose I plan to ride your bicycle from Portland Oregon to Seattle Washington and back to Portland.

Portland and Seattle are 175 miles apart. I plan to travel 25 miles every day.

If we consider the starting point i.e. Portland as the zero distance i.e. reference, then we can model the distance from Portland d(x) as

d(x) = 175 - |175 - 25x|

where x is the number of days into the ride. (Answer)

Twice the sum of two numbers is 24. if one number is 2 times larger than the other, what is the smaller of the two numbers?
Vikki [24]
2(x+y)=24
2x=y

Use substitution. If y=2x, than we can substitute 2x for it in the other equation, because x and y equal the same things in both equations. 

So using that we get 2(x+2x)=24

SIMPLIFY
2(3x)=24

DISTRIBUTE
6x=24. 

DIVIDE: x=4.

If we substitute x into the original equations we get x=4 and y=8. Those are your two numbers. 

Have a nice day! :)

V125BC [204]

Answer:

<u>24 pieces</u> of fruits are use to make 2 fruit salads.

Step-by-step explanation:

Given:

Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad.

Now, to find the number of pieces of fruit Ken will use to make 2 fruit salads.

So, pieces of fruits use to make a salad are:

Apples = 6.

Bananas = 2.

Oranges = twice of bananas = 2×2=4.

So, total pieces of fruits to make a salad = 6+2+4=12.

Now, total pieces of fruits to make 2 fruit salads:

(6+2+4)\times 2

=12\times 2

=24.

Therefore, 24 pieces of fruits are use to make 2 fruit salads.

Can you help me please?

Finding the volume of a cube involves multiplying with this formula.

Height * Width * Length = volume

To find what the side lengths are, we can take the cube root of 64.

∛64 = 4

Height = 4

Width = 4

Length = 4

These sides are multiplied together to get 64.

The only answer choice that makes sense is Option A.
