Answer:
Yes
Step-by-step explanation:
Every time the sugar goes up by 1/3 or by three it keeps the same raito
Plug in 1.5 for x, to start off. It is then simplified to : 3*(1.5)* y - 5y
Then plug in -3 for y, it's then simplified to : 3*(1.5)* -3 - 5 * (-3)
First, multiply 1.5 times 3, and that will get you 4.5. The multiply 4.5 with -3, and that will get you -13.5. Moving on, subtract -13.5 from the 5 that is being multiplied to -3, which is -15. In conclusion, -13.5 subtracted from -15 would be -28.5. Hope this helps!
