I'm pretty sure the answer to your question is -3/5 + 4/5. C.
Answer: Infinite solutions
Step 1: Turn this into y=Mx+b form
The current equation is—
-2x+5y=30
Since we want to get y alone on the left side, let’s add 2x on both sides
-2x+5y=30
+2x +2x
____________
5y=2x+30
Step 2: Again, trying to get y alone, we need to divide 5 on both sides
5y=2x+30
/5 /5 /5
________
y=2/5x+6
Step 3: Now that we know how to find y, substitute that in where y is in the equation
-2x + 5(2/5x+6) = 30
-2x + 2x + 30 = 30
30=30
Seeing that you cannot get a specific answer for y when solving, there is an infinite number of solutions

Step-by-step explanation:
these could be negatives
Answer: Priya practiced for <u>189 minutes
</u>
Tyler practiced for <u>123 minutes
</u>
-------------------------------------------------------------------------------------------------------------
The Explanation: Now, Han spent 75 minutes practicing the piano over the weekend
Then, Priya practiced the violin for 152% as much time as Han practiced the piano.
Priya = 152% of 75 minutes + 75 minutes
= 152/100 × 75 + 75
= 1.52 × 75 + 75
= 114 + 75
= 189 minutes
Finally, Priya practiced for <u>189 minutes</u>
-------------------------------------------------------------------------------------------------------------
Tyler practiced the clarinet for 64% as much time as Han practiced the piano.
Tyler = 64% of 75 minutes + 75 minutes
= 64/100 × 75 minutes + 75 minutes
= 64 / 100 × 75 + 75
= 0.64 × 75 + 75
= 48 + 75
= 123 minutes
Lastly, Tyler practiced for <u>123 minutes</u>
Answer:
the sum is 24
