Answer:
B
Step-by-step explanation:
recall that any radical expression 
has real solutions only if A is not negative. (otherwise you will have imaginary solutions)
hence in this case we have
,
for real solutions, 8x must be ≥ 0,
since 8 is a positive number, x must be ≥ 0 (answer)
Answer:
Step-by-step explanation:
Required
<em>Write as equation</em>
<em></em>
Taking the statement one at a time, we have
Two third of x: 
Plus 6: 
is 10:
<em>Hence, the equivalent of the given statement is </em><em></em>
Answer:
a = 1/2
Step-by-step explanation:
a - 3/10 = 1/5
Add 3/10 to each side
a - 3/10 +3/10 = 1/5+3/10
a = 1/5+3/10
Get a common denominator
a= 1/5*2/2 +3/10
a = 2/10 +3/10
a = 5/10
Divide the top and bottom by 5
a = 1/2
Answer:
-1
Step-by-step explanation:
its -1 because negative * negative is positive. so make the -10 a 10 and subtract 3 and boom you have 7.
