1.5 x

Step-by-step explanation:

Ok so what you want to know before you start this is that 1.25 x10^6 is really

1250000 you just move the decimal place 6 places back; if it was a -6 you would move the decimal place 6 places forwards.

1,250,000+ 250,000 = 1,500,000

then to convert back to  scientific notation just move to the first number and place the decimal then count the zeros.

EX:

1.500000 --count zeros + the 5 because you moved the decimal in front of it too, and you are left with =

1.5 x 10^6

step-by-step explanation:

because i said it is

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
