Answer:
20
Step-by-step explanation:
x / 100 = 0.2
Multiply both sides by 100 to isolate x. 100 x 0.2 = 20
I'm going to make some assumptions here:
That your sqrt8x= sqrt4+2x means √(8x) = √(4+2x). (There are other interpretations.)
Squaring both sides, 8x = 4 + 2x, or 6x = 4, or x = 4/6, or x = 2/3.
Answer:
4/100 is the fraction
Step-by-step explanation:
there are four blue blocks shaded out of the 100
X^2 = 81...take the square root of both sides, eliminating the ^2
x = (+-) sqrt 81
x = (+-) 9
answers are : -9 and 9
