How do i figure out 2/3(5*4)/3+6/7=

work out the product in the parenthesis firat:-

2/3(5*4)/ 3 + 6/7

= 2/3(20) / 3 + 6/7

= 40/3 / 3 + 6/7

= 40/9 + 6/7

= 334/63

First start off by: multiplying 5 * 4 = 20

Second do: 2/3 times 20 that equals 40/1 or 40 (2 times 20 / 3 times 1 = 40/1)

Third try: Dividing 40/3 (3 = 40/3 times 1/3 equals 40 times 1 / 3 times) this equals 40/9

Fourth and the Final step: Add 40/9 plus 6/7 (40 · 7

9 times 7 plus 6 times 9 / 7 times 9 = 280 /63 + 54 /63 = 280 + 54 /63 = 334 /63

The correct answer is 334/63

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'.
