The answer is 6x. You divide 42 by 7. Take out the x. 42 divided by 7 will equal 6.
Your ratio is 4:1 because it takes 4 cups of water for every cup of sugar.
Answer:
7c^2d-7c+4d-10
Step-by-step explanation:
Start off with the term that has c^2 in it. 5c^2d + 2C = 7c^2d, then since you have multiple choice, the d value differs between the two answer choices that have 7c^2d so you can do +3d +d to get +4d to get the fourth answer choice.
To check your work, you can add/subtract each term to see if you get 7c^2d-7c+4d-10
You draw a number line do +100 on the line then do +100 +100 +50 +8 then you add them up
