Drag the tiles to the correct boxes to complete the pairs. Simplify the mathematical expressions to determine the product or quotient in scientific notation. Round so the first factor goes to the tenths place. 3.3 x103 7.8 3.7 2.1x10-3 (8.6x107):(9.1x10-8) (6.9x105).(4.8x10-3) (3.7 x 102).(4.6 x 10-3) (1.4 x 10-6).(5.7 x 108) (3.1 x 105) - (5.3 X 10-9) (7.3 x 102) (6.1 x 10-?)​

its definatley   this on your answer choice?

step-by-step explanation:

cats

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
