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.
I hope that explains it.

Answer:
C
Step-by-step explanation:
The difference formula for cosine is
cos(x - y) = cosxcosy + sinxsiny
Consider
cos75 = cos(120 - 45)°, then
cos(120 - 45)°
= cos120°cos45° + sin120°sin45° → C
Answer:
$221
Step-by-step explanation:
Hello!
The total cost s $627.83, for one desk that costs $185.83, and two identical chairs (c).
The equation: $185.83 + 2c = $627.83
This equation represents the cost of the desk plus two chairs of the same price, which adds up to the total price.
Solve for c:
- $185.83 + 2c = $627.83
- 2c = $442
- c = $221
Each chair, c, costs $221.
The answer is the middle option. It is ideal to solve using substitution for x in this system of equations.
