David, Malachy and Paul share some sweets in the ratio 4:3:4. David gets 44 sweets. How many sweets are there altogether?

121 sweets

Step-by-step explanation:

David is the first 4 in the ratio 4:3:4. We know that David gets 44 sweets. We also know that Paul gets 44 sweets because he is the other 4 in the ratio. To find out how many sweets 3 is equal to, you need to find the unit rate. To do this, you can divide 44 by 4 to know how much 1 equals. When you divide 44/4, you get 11. This means that 1 is 11. To find out what three is, you can multiply 11 by 3 to get 33. The question asks how many sweets are there altogether, so you must add 44+33+44. This equals 121.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
