In other words, which equations have equivalent expressions? true. 2t + 3t = 6t y + y + y = y(1 + 1 + 1) 3(2 + x) = 6 + 3x 2a + 2b = 4ab x + 3 = 4x

2t + 3t = 6t is false. The correct answer is 5t.

y + y + y = y(1 + 1 + 1) is true. Correct answer is 3y.

3(2 + x) = 6 + 3x is true. This is an application of the distributive rule for mult.

2a + 2b = 4ab is false. a and b are separate variables with no given relationship to each other. Correct answer would be 2(a+b).

x + 3 = 4x is false. x + 3x = 4x would be true.

this is the answer for you hope it

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
