√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1
It would be 3 because .50 and up is one up and .49 and down is is one down
C. 2/100....
48.52=48+0.50+0.02
Also, 0.02=2/100
Hope it helps!
