Which steps can be used to solve for the value of y ? 2\3(y+57)=178

Answers

Answer 1

Answer: Multiply both sides by 3 to get rid of the fraction to make your life easier.
2(y+57)=534
Apply the distributive property.
2y+114=534
Subtract 114 from both sides.
2y=420
Divide both sides by 2.
y=210

Answer 2

Answer: $(2)/(3)(y+57)=178\n \n (2)/(3) \cdot y+(2)/(3)\cdot 57 =178 \n \n (2)/(3) \cdot y+(2)/(\not3^1)\cdot \not57^(19) =178 \n \n (2)/(3) \cdot y+2\cdot 19 =178 \n \n (2)/(3) \cdot y +38 =178 \n \n (2)/(3) \cdot y=178-38 \n \n (2)/(3) \cdot y =140 \ \ /\cdot (3)/(2)\n \n (3)/(2) \cdot (2)/(3) \cdot y =140\cdot (3)/(2) \n \ny=70 \cdot 3 \n \n y=210$

If Georgia is 59,424.77 square miles, then what is the area of Georgia rounded to the nearest square mile?

Answers

59,424.77 rounded to the nearest square mile would be 59,425 because the .77 would get rounded up to a 1. That 1 gets added to the 424, hence 59,425.

59,424.77's tenths is 7 which means we had to rounded up instead of keeping the ones, so if we add the 1 that had represented the 7 on the tenths, then 59,424+1=59,425, which means the answer would be 59,425.
