What is the answer for 4a+2b=16
Dmitry_Shevchenko [17]
First, move all terms containing a to the left, all other terms to the right.

Add '2b' to each side of the equation.
4a + -2b + 2b = 16 + 2b

Combine like terms: -2b + 2b = 0
4a + 0 = 16 + 2b4a = 16 + 2b

Divide each side by '4'.
a = 4 + 0.5b

Answer
 

= 4 + 0.5b

You are the administrator of an annual essay contest scholarship fund. This year a $80,000 college scholarship is being divided
Hatshy [7]

Answer:

Runner Up Amount=$16,000

Winner Amount=$64,000

Step-by-step explanation:

Amount of the college's scholarship=$80,000

The fund is being divided between the top two contestants so that the winner receives four times as much as the runner-up.

Therefore: we can say it is being divided into 5 parts where the winner gets 4 parts and the runner up gets 1 part, i.e in the ratio 4:1.

Runner Up Amount=\dfrac{1}{5}X\$ $80,000=\$16000

Winner Amount=\dfrac{4}{5}X\$ $80,000=\$64000

The winner gets $64,000 and the runner up gets $16,000.
