The answer is essentially 4^4 * 10^6

4^4 is 256, and 10^6 = 1,000,000

Knowing this, the answer should be 256,000,000

Step-by-step explanation:

$\frac{2x - 1}{4} + \frac{x}{3} = 2$

find a common denominator of 12 for each fraction

$\frac{3}{3} \times \frac{(2x - 1)}{4} + \frac{4}{4} \times \frac{x}{3} = \frac{12}{12} \times \frac{2}{1}$

$\frac{6x - 3}{12} + \frac{4x}{12} = \frac{24}{12}$

$\frac{6x - 3 + 4x}{12} = \frac{24}{12}$

$\frac{10x - 3}{12} = \frac{24}{12}$

multiply both sides by 12

$12 \times \frac{10x - 3}{12} = \frac{24}{12} \times 12$

12s cancel out

$10x - 3 = 24$

add three to both sides

$10x - 3 + 3 = 24 + 3$

$10x = 27$

divide both sides by 10

$\frac{10x}{10} = \frac{27}{10}$

The tens on the left side cancel

$x = \frac{27}{10} = 2.7$

Circle A has a diameter of 9 inches, a circumference of 28.26 inches, and an area of 63.585 square inches. The diameter of circl

sergiy2304 [10]

A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.
B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)
C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14
