Answer from: colebash88

Distribute 4.5 to 8- x and distribute -2.5 to 3x-24 to get 36-4.5x+36+102-7.5x+60, then add like terms to get 3x=90

Answer from: weeman7760

Simplifying 4.5(8 + -1x) + 36 = 102 + -2.5(3x + 24) (8 * 4.5 + -1x * 4.5) + 36 = 102 + -2.5(3x + 24) (36 + -4.5x) + 36 = 102 + -2.5(3x + 24) Reorder the terms: 36 + 36 + -4.5x = 102 + -2.5(3x + 24)

Combine like terms: 36 + 36 = 72 72 + -4.5x = 102 + -2.5(3x + 24)

Reorder the terms: 72 + -4.5x = 102 + -2.5(24 + 3x) 72 + -4.5x = 102 + (24 * -2.5 + 3x * -2.5) 72 + -4.5x = 102 + (-60 + -7.5x)

Combine like terms: 102 + -60 = 42 72 + -4.5x = 42 + -7.5x Solving 72 + -4.5x = 42 + -7.5x Solving for variable 'x'.

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

Add '7.5x' to each side of the equation. 72 + -4.5x + 7.5x = 42 + -7.5x + 7.5x

Combine like terms: -4.5x + 7.5x = 3x 72 + 3x = 42 + -7.5x + 7.5x

Combine like terms: -7.5x + 7.5x = 0.0 72 + 3x = 42 + 0.0 72 + 3x = 42

Add '-72' to each side of the equation. 72 + -72 + 3x = 42 + -72

Combine like terms: 72 + -72 = 0 0 + 3x = 42 + -72 3x = 42 + -72

Combine like terms: 42 + -72 = -30 3x = -30

Divide each side by '3'. x = -10

Simplifying x = -10

answer: you need the equation in the question so i can answer it

step-by-step explanation:

Answer from: Quest

(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
