Nick likes to use 12 of a chocolate bar to make a s'more Tasha will only eat a s'more that is made with exactly 25 of a chocolate bar what fraction of a chocolate bar will nick and Tasha use in total if they each eat one s'more

Question:

Nick and Tasha are buying supplies for a camping trip. They need to buy chocolate bars to make s’mores, their favorite campfire dessert. Each of them has a different recipe for their perfect s’more. Nick likes to use 1/2 of a chocolate bar to make a s’more. Tasha will only eat a s’more that is made with exactly 2/5 of a chocolate bar.

The fraction of a chocolate bar will Nick and Tasha will use in total if they each eat one s'more is bar.

Step-by-step explanation:

Here, we are meant to learn how to add fractions and to know about the essence of a common denominator

The portion of the chocolate that Nick makes an s'more with is 1/2

The portion of the chocolate that Tasha makes an s'more with is 2/5

Therefore the fraction of the chocolate bar Nick and Tasha use in total if they each eat one s'more is 1/2 + 2/5

Where +  multiplying the fraction by and    by   wee have

× + ×  =   +   =   bar

Therefore the fraction of the chocolate bar that would be left is

1 bar -   bar = bar.

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
