A:12=4:10

The extremes are a and 10
The middles are 12 and 4

We know that PRODUCT OF MIDDLE = PRODUCT OF EXTREMES
a*10=12*4
a = 48/10
a = 4.8

Therefore, the value of a = 4.8

A/12= 4/10

Cross multiply: 12*4= a*10
⇒ a= 12*4/10= 4.8

Final answer: a= 4.8

5x-10x+ 2(3y-2)= 10y-5x + 4

Bas_tet [7]

5x-10x+ 2(3y-2)= 10y-5x + 4

Multiply 2 x 3y and by -2

5x-10x+6y-4=10y-5x+4

You get 6y-4

-5x+6y-4=10y-5x+4

Subtract 10x from 5x to get -5x

6y-4=10y+4

Add 5x to the -5x

6y=10y+8

Add 4 to the other side to get 8

-4y=8

Subtract 6y-10y to get -4y

-4y/-4=8/-4

Divide -4y and 8 by -4 to get y by itself and -2

Y=-2
