Answer:
The variable y should equal 5 2/5 or 5.4 as a decimal.
Step-by-step explanation:
The variable x equals 1 so we can replace x in the equation y = 2/5x + 5 with 1.
y = 2/5(1) + 5
This is our new equation. Any number multiplied by 1 will equal itself so in this case, 2/5 times 1 equals 2/5 or 0.4 in decimal form. Now we can add 2/5 or 0.4 to 5 and we will get 5 2/5 or 5.4. Now we will only have y = 5 2/5 or 5/4 in the equation and this is where we will stop solving for y. In conclusion, y equals 5 2/5 or 5.4. I hope this helps! If this answer is wrong, please give me some feedback on what I did wrong! Thank you!
