Answer:
y+30
Step-by-step explanation:
the sum of the numbers is 15y
the new sum after increase each number by 30 is 15y+450
the new mean 15y+450/15
= y+30
351.3 you can use calculators you know lol
First, we subtract 12x from both sides. We then get -4y=-12x+48. We then divide this by -4 on both sides to get the y by itself. We then get that the equation is y=3x-12.
Change 4 feet to inches.
You need to know that for every
feet, there are 12 inches. So, if you have 4 feet, you just multiply 4 by 12
and you will get 48 inches. Note that the feet unit is larger than inches.
