Answer:
288
Step-by-step explanation:
Attached the solution and work.
You always begin by the Given equation, which is in this case:
y+

= 3x
To remove the fraction, you multiply the whole equation by 5:
5y + 1 = 15x
Then, you move the "15x" the left-side of the equation, changing it's sign
-15x + 5y +1 = 0
You move the "1" to the right side, changing it's sign
-15x + 5y = -1
So the correct answer is A :)
Hope it helped! ^^
Answer:C
Step-by-step explanation:
Answer:
y = 3
Step-by-step explanation:
Since ABCD is similar to EFGH, therefore, the ratio of their corresponding sides are equal. Thus:
AB/EF = CD/GH
AB = 3
EF = 2
CD = 4.5
GH = y
Substitute
3/2 = 4.5/y
Cross multiply
3*y = 4.5*2
3y = 9
Divide both sides by 3
3y/3 = 9/3
y = 3
