Answer:
-9
Step-by-step explanation:
Substitute the give values into the correct place in the equation.
Since x=2, y=3,
Place "2" in the x of the equation, and "3" into the y of the equation.
x²-5y+2
= 2² - 5(3) + 2
= 4 - 15 + 2
= -9
X/750=4
multiply both sides by 750
x=3000
the number is 3000
250*0.62= 155
155 pounds is your answer.
