Answer: The answer is 3 3/5 because you divide 2 1/4 and 5/8 you do KCF keep change flip but since it is a whole number divided by a fraction you multiply the whole number with the denominator and than add it by the numerator so no the problem is 9/4 • 8/5 which is 72/20 which is a improper fraction so it is 3 12/20 but it can be reduced to 3 3/5 and thats how you do it.
Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
For this question you must know about 45 45 90 triangles and 30 60 90 triangles and their special properties first you have to find the hypotenuse of the 45 45 90 triangles which is always square root of two times a leg in this case 10. so now you have 10squareroot2 the longer leg is sqare root 3 times the shorter leg in a 30 60 90 triangle
x=10squareroot6
and y is 2 2 times larger than the shorter side
y=20squareroot3
All you do is divide 67,585.06 by 19,200 which is 3.52005521 rounded t nearest cent that's 3.52
