Answer: 14
Explanation:
9-2x
-8y + 9x = -5
8y + 7x = -75 +
--------------------------
/ 16x = -80
x = -80/16
x = -5
8y + 7x = -75
8y - 35 = -75
8y = -75 + 35
8y = -40
y = -40/8
y = -5
Answer : x = y = -5
Answer: 42
Step-by-step explanation:
Here given numbers : 28 and 63
so Mean = √x * y
let x = 28 and y = 63
<em>So mean proportion between them is:</em>
M = √63 * 28
M = √1764
M = 42
- therefore the mean proportion between 28 and 63 is 42
