The first one is correct!
Answer:
58 students
Step-by-step explanation:
11 * 5 = 55
55 + 3 = 58
Answer: 84
Step-by-step explanation:
When substituting this question into an algebraic equation you can write it as:
21=.25x
(x clearly represents the number you are trying to find)
When you divide both sides by .25 to isolate x you get x=84
6 and 30. 6 is 1/5 of thirty. If the first number is x,that means that the second number is 5x. Combine like terms. 6x = 36. 36/6 = 6. x = 6. The first number is 6. the second number is 5x. Replace x with 6. 5 * 6 = 30. 30 is the second number.
What about if you use the distributive property? You could do 1(x+13) because the 1 would distribute to the x and the 13 making it x+13. Hope that is helpful.
