Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old

answer: Riley practiced soccer for 2 1/4 hours Monday and Tuesday. she practiced 2/4 more hours on Wednesday than Tuesday.
explanation: 1/2 is essentially 2/4, add 3/4 it becomes 1 1/4 now add one for 2 1/4.
this is quite self explanatory. 1 1/4 - 3/4 is step by step like this. 1 1/4 - 1/4= 1.
1- 2/4 (half of one whole.) = 2/4.
