How many times does 0.30 fit in 0.90? Well, exactly 3 times since 9 is 3 times more than 3!
Hope this helps!
Divide both sides by -5
Sqrt(x) = 3
We want to isolate x to solve for it. The opposite of a square root is a square, so square both sides.
x = 9
It can't be -9 because the square root of negative numbers are not real numbers.
Answer: $15
There are about 4 weeks in a month, so if you spend $60 per month, you would spend 1/4 of that every week.
60/4= $15
Answer:
the first one I guess
Step-by-step explanation:
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
