Solve for the equation 4a-8=28

hoa [83]

4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9

Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of -

Law Incorporation [45]

Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625

Step-by-step explanation:

Given: Vanessa and Zack are playing a game where the player with the lower score wins.

Score of Vanessa= $-3\frac{5}{8}=-(\frac{29}{8})=-3.625$

Score of Zack = $-3\frac{2}{3}=-(\frac{11}{3})=-3.666$

We can see $-3.666$

⇒ Zack has the lower score .

Hence, Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
