Question

4) 40,32 : (406,2-x) = 2,1​

Answer 1

40.32=2.1(406.2-x)

40.32 = 851.82 - 2.1x

-811.5 = -2.1x

x ≈ 386.43

40,32 : (406,2-x) = 2,1 x ≈ 386.43.

Answer 2

To solve the proportion 40/32 : (406/(2-x)) = 2/1, you can cross-multiply and solve for x:

40/32 = 2/1 (406/(2-x)) = (32/40)

Now, cross-multiply:

40 * (2-x) = 32 * 406

Now, simplify and solve for x:

80 - 40x = 32 * 406

Now, subtract 80 from both sides:

-40x = 32 * 406 - 80

Next, divide by -40 to isolate x:

x = (32 * 406 - 80) / -40

Now, calculate the right side:

x = (13072 - 80) / -40

x = 13072 / -40 - 80 / -40

x = -326.8 + 2

x ≈ -324.8

So, the value of x is approximately -324.8.
