The nutrition information on the box of cereal says that a one third cup serving provides 80 calories and six grams of dietary fiber. at that rate find how many calories and grams of fiber are in a half cup serving

120 calories and 9 grams of fiber.

Step-by-step explanation:

We are told that 1/3 cup serving contains 80 calories and 6 grams of fiber.

Let's multiply everything by 3. So,

1 cup serving has 3*80 = 240 calories and 3*6 = 18 grams of fiber.  

But, we want to really know about 1/2 cup. So, now we multiply everything by 1/2.  

1/2 cup has (1/2) (240) = 40 calories and (1/2) (18 grams) = 9 grams of fiber.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
