4x + 5y = 2(x + 3y)
4x + 5y = 2x + 6y <em>distributed 2 on the right side</em>
2x + 5y = 6y <em>subtracted 2x from both sides</em>
2x = y <em>subtracted 5y from both sides</em>
if y = 2x
then 17(y) = 17(2x)
17y = 34x
Answer: 34x
261_209=u
-52=u

Set an equation:
4/5=x-3/x+1
cross multiply
5x-15=4x+4
x=19
Width: 16 cm
Length: 20 cm
Find the perimeter and the area:
Perimeter: 16+16+20+20=72
Area: 20•16=320
Ratio: 320:72
Simplify the ratio:
40:9
Answer: The ratio of the area to the perimeter is 40:9.
Answer:
0.00139626
Step-by-step explanation:
Answer: The y intercept is 1.
Step-by-step explanation: Sorry I could only answer the one about the y-intercept. So basically finding the y intercept is where the line crosses at the y-axis. So in this case the y-intercept is 1 because thats the point the line crosses at the y-axis. I hope this clarifies your question and I hope this helps. Good Luck on your upcoming test if you have one soon!
