8/6 20/x the figures are similar find x

Lana71 [14]

The process:

8/6 = 20/x

You would have to cross multiply first.

8 20 6×20= 120
6 x 8×x=8x

Then you rearrange the equation,

120=8x

And you divide by 8 ( because it has the variable next to it)

120÷8=15

So, x=15

Can someone ask me about this, which is algebra, please

krok68 [10]

Answer:

The correct answer is not shown in your picture. You must get a = 60.

Step-by-step explanation:

(1/2)a + (2/3)b = 50

b = 30

(1/2)a + (2/3)(30) = 50

(1/2)a + 20 = 50

(1/2)a + 20 - 20 = 50 - 20

(1/2)a = 30

2 * (1/2)a = 2 * 30

a = 60

The correct answer is not shown in your picture. You must get a = 60.
