Answer:

Step-by-step explanation:

12 times x (the first square) is equal to 16 times x-2 (the second square)

$12x = 16(x-2)$

Distributed

$12x = 16x-32$

Simplified (divided by 16)

$0.75x = x-2$

Subtract x from both side of the equation

$-0.25x = -2$

Both negatives cancel each other out

$0.25x = 2$

0.25 times what equals 2,...

$x = 8$

Hope it help,... and I'll see you in life,... well not really, but you get the idea,... Chow,...!

Answer:

2.a) 3 ( x - 1 ) = 5x - 6 (Because the sides of a square are always equal)

b) 3 ( x - 1 ) = 5x - 6

=> 3x - 3 = 5x - 6

=> 3x - 5x = -6 + 3 (Law of transposition)

=> -2x = -3

=> -x = -3/2

=> -x = -1.5

=> x = 1.5 (By cancelling out the negative sign from both the sides)

c) 3(x-1) = 3 (1.5 - 1)

=> 3 (0.5)

=> 3 * 0.5 = 1.5

Both the angles are 1.5 because they are equal

Which of the following is the missing reason? Statements Reasons two thirds times x plus 7 equals negative 5 Given 2x 21 = â’15

pentagon [3]

The correct option is B. Distributive property

Given,

$\frac{2}{3} x+7=-5\\$

On solving the above equation,

multiplying both sides by 3 we, get

$2x+21=-15$

now subtracting 21 from both the sides,

$2x=-36\\$

dividing both the sides by 2 we get,

$x=-18$

Since in the above steps we follow all the giving property except the distributive property.

Hence the correct option is B. Distributive property.
