Marshmallows cost 2$ and ounce and have 500 calories in an ounce . cookies cost 3$ an ounce and have 400 calories in an ounce. a mixture of marshmallows and cookies cost $29 and has 4,800 calories. create a system of equations to model this scenario. how many ounces of marshmallows are there in the mixture ?
i’m stuck ! : (

4oz of marshmallows

Step-by-step explanation:

Given:

Marshmallows ==> $2 per oz ; 500 cal per oz

Cookiess ==> $3 per oz ; 400 cal per oz

Mixture of marshmallows and cookies ===> Cost $29 ; has 4,800 calories

let the number of marshmallows be M

let the number of cookies be C

Considering price:

2M + 3C = 29 eq 1

Considering Calories:

500M + 400C = 4800 (divide by 100)

5M + 4C = 48 eq 2

Solving the system of equations using your favorite method of choice will give:

M = 4 and C = 7

Hence there are 4 oz of marshmallows

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
