Answer:
77:56:48
77:48
Step-by-step explanation:
If x:y=11:8 and z:y=6:7
then;
x/y = 11/8 and z/y = 6/7
11y = 8x and 6y = 7z
x = 11y/8 anad z = 6y/7
Hence;
x:y:z
= 11y/8:y:6y/7
= 11/8:1:6/7
= 11/8 * 7/6
= 77:56:48
x:z = 11y/8:6y/7
x:z = 11/8:6/7
x:z = 77:48
Answer: A = -3, B = 1, and C = 19 OR A = 3, B= -1, C = -19 (look at the explaination)
Step-by-step explanation:
You will need to expand the equation given to you.
y-7 = 3(x+4)
y-7=3x+12
y- 7 + 7 = 3x + 12 +7
y = 3x + 19
-3x + y = 19
Therefore, A = -3, B = 1, and C = 19
But, you can also write it as:
y = 3x + 19
3x - y = -19
A = 3, B= -1, C = -19
So, I don't know what your teacher wants but both answers should be right.
