Answer: The answer is sin A = cos C
Step-by-step explanation: sin A = cos C
Change 15/20 to 3/4
Now we have

multiply 6 to 3= 18 ÷ 4 = 4.5
x = 4.5
To find the difference between (6x-7y) and (4x+3y) would be by subtracting both the equations. To start, first set up an expression:
(6x-7y)-(4x+3y)
When done, subtract any like terms and add the remaing together:
(6x-4x) +(-7y-3y)
This will result in your answer, 2x-10y
Answer:
1 13/60
Step-by-step explanation:
find common denominator, 60.
convert both to 60ths by multiplying
4/5 * 12 = 48/60
5/12 * 5 = 25/60
25/60 + 48/60 = 73/60 = 1 13/60
