Ann, ben, and cindy were eating skittles. the ratio of the numbers of candies they ate is 5: 5: 7. if cindy ate 30 skittles less than ann and ben together, what is the total number of skittles the three of them ate?

170 skittles

Step-by-step explanation:

Ann and Ben together ate 5+5=10 ratio units of Skittles. That is 10-7 = 3 more ratio units than the number Cindy ate. That difference of 3 ratio units corresponds to a difference of 30 Skittles, so each ratio unit must stand for 10 Skittles.

The total number of ratio units is 5+5+7 = 17, so the total number of Skittles is ...

... 17 × 10 = 170

ik how do do this just give me a few minutes and i will give it to

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
