Answer:
x = -6
Step-by-step explanation:
3/ x = 4/(x-2)
Using cross products
3 (x-2) = 4x
Distribute
3x - 6 = 4x
Subtract 3x from each side
3x-3x-6 = 4x-3x
-6 =x
I think the answer will be 17 square that what my friend said.
Answer:
C. 7
Step-by-step explanation:
Therefore, by Basic Proportionality theorem:

Y/6 - 5 = 2. First add 5 to both sides. Then multiply both sides by 6. The answer to y is 42. To check plug in 42 for y. 42/6 -5 = 2 ==> 7-5 = 2 ===> 2=2. Therefore it is correct. ANSWER: y=42.
Answer:
45:36 is the answer.
Step-by-step explanation:
Divide 81 by sum of ratio.
81/(5+4)=81/9=9
So,
5×9 : 4×9
45 : 36
Check: 45+36=91
