Answer:
Step-by-step explanation:
The goal to solving any equation is to have x = {something}. That means we need to get the x out from underneath that radical. It's a square root, so we can "undo" it by squaring. Square both sides because this is an equation. Squaring both sides gives you
Get everything on one side of the equals sign and set the quadratic equal to 0:
Throw this into the quadratic formula to get that the solutions are x = 5 and -8. We need to see if only one works, both work, or neither work in the original equation.
Does 
?
and
and 5 = 5. So 5 works. Let's try -8 now:
and
so
-8 = 8? No it doesn't. So only 5 works. Your choice is the third one down.
Answer:
8

50+8
50 represents tens place value, while 8 represents the ones place value.
Answer:
Step-by-step explanation:
The equation
2 = (1/6)x represents this situation.
2 is 1/6 of some value. In this case, the value is the total number of marbles. 2 represents 1/6 of the total number of marbles is how to read that equation in context. Solve that equation for x
2 = (1/6)x
12 = x (multiply both sides by 6 to get rid of the fraction)
