Answer:
$8.75
Step-by-step explanation:
Create a proportion where x is the cost for 7 bags:
= 
Cross multiply and solve for x:
4x = 35
x = 8.75
So, the cost of 7 bags is $8.75
Answer: D
Step-by-step explanation:
As you can see it is switch from -3 to 3.
Why?
Because each time it is being multiplied by -1 so it switches from negative to positive and geometric sequences involve multiplication (and division so technically it could be dividing by -1).
That would be

, but it is also equal to just

. You would simplify the

part, and you would get

, or if you need a decimal,

But don't forget the negative part, so the answer would be

or
Answer:
The total number of rungs on the ladder are 16 rungs .
Step-by-step explanation:
Given as :
At first the climb up number of ladder = 3 rungs
At second the climb down number of ladder = 5 rungs
At third the climb up number of ladder = 10 rungs
Let The total number of rungs on the ladder = x
Now, According to question ,
The total number of climb up ladder = First + Third
I.e The total number of climb up ladder = 3 + 10 = 13 rungs
And The total number of climb down ladder = 5 rungs
So , From the middle of rungs = total number of climb up ladder - total number of climb down ladder
I.e
= 13 rungs - 5 rungs
∴ x = 8 × 2 rungs
I.e x = 16
Hence The total number of rungs on the ladder are 16 rungs . Answer
