Jane had 275 stickers, which she gave to her friends. each friend got five more stickers than the friend before. if the first friend got 5 stickers, how many friends got stickers from jane?

10 friends

Step-by-step explanation:

we know that

The formula of the sum is equal to

where

a1 is the first term

n is the number of terms (number of friends)

d is the common difference in the arithmetic sequence

In this problem we have

----> the common difference

substitute in the formula and solve for n

Solve the quadratic equation by graphing

The solution is n=10

see the attached figure

therefore

She had 10 friends who got stickers

after simplifying it i got: -36.25 as my answer. hope that !

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
