2x + 2x + 2x = 12
6x = 12

2x - 1 = 3
2x = 3 + 1
2x = 4
x = 2

Nataliya [291]

Here you can use proportion:

The ratio betwen €1.2 to £1

Mathematically this means that

\dfrac{1.2}{180} =\dfrac{1}{x}.

Now

1.2\cdot x=180\cdot 1\\\\ x=\dfrac{180}{1.2} \\ \\x=150

What percent of 950 is 2​
Dima020 [189]

Answer: 0.21%

Step-by-step explanation: Please mark me brainlist

Step 1: We make the assumption that 950 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3: From step 1, it follows that 100% = 950

Step 4: In the same vein x% = 2

Step 5: This gives us a pair of simple equations: 100% = 950(1)

x% = 2(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have
100%/x% = 950/2

Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%/ 2/950
---> 0.21%
