A recipe that serves 6 people requires 210 grams of sugar what is the total amount of sugar needed if the recipe is changed to serve 10 people

350 grams

Step-by-step explanation:

- 6 people = 120

 10 = ?

- this is how like to use ratios

  6 : 120  

  10 : x

- multiply the numbers in a criss-cross fashion

so,  

- multiply 120*10 and devide by the number multiplying with the unknown ( 6 in this case  )

- (120*10)/6 = 350

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

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
