<em>Answer:</em>
<em>x ≅ 79.1</em>
<em>Step-by-step explanation:</em>
<em>10log(4x) = 25 </em>
<em>2log(4x) = 5 </em>
<em>log((4x)²) = 5 </em>
<em>(4x)² = 10⁵ </em>
<em>16x² = 100,000 </em>
<em>x² = 6,250 </em>
<em>x ≅ 79.1</em>
X - 3(x + 4)
-------------
x^2 - 1
vertical asymptoes happen when the denominator = 0
x^2 - 1 = 0
so x = 1 or -1
so the asymptotes are x = -1 and x=1
Not sure is this is right but if the chemist wants to make the solution 35% acidic then he can use all of the 30% acid and 5% of the 45% acid.
Answer:
x = 5
Step-by-step explanation:
15 / 3 =5
In 1 millimeter, there are 0.00109361
So in 2 mm, there are 2 × 0.00109361 = 0.00218722 yards
or do proportions:

=

Cross multiply:
2 × 0.00109361 = y
0.00218711 = y
0.00218722 yards are in 2 millimeters.
