Eli is making a party mix that contains pretzels and chex. for each cup of pretzels, he uses 3 cups of chex. how many cups of pretzels and how many cups of chex does he need to make 12 cups of party mix?

3 cups of pretzels and 9 cups of chex he will need.

Step-by-step explanation:

Ratio of pretzel to chex = 1:3

Let the cup of pretzel be 1x

Let the cup of chex be 3x

1 x+ 3x = 12

4x = 12

Cups of pretzel required = 1x = 1 × 3 = 3

Cups of chex required = 3x = 3 × 3 = 9

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
