Answer:
y= -6+2/3x
Step-by-step explanation:
2x-3y=18
Minus the 2x from both sides
-3y=18-2x
Then divide both sides by -1
-3y÷-1=18÷-1 -2x÷-1
Lastly divide both sides by 3
3y÷3= -18÷3+2x÷3
Answer 9x^2
Step-by-step explanation:
3x^2+6x^2=9x^2
Answer:
Real numbers are "closed" under multiplication
Irrational numbers are "not closed" under division
Integers are "closed" under subtraction
Positive ration numbers are "closed"
Hope this helps! :)
Yes. Parenthesis first, then if any exponents, then multiplication or division, then addition and subtraction. PEMDAS.
y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
