Here is the work to figure this out:

3x-4=5 —-> 3x=9 ——> x=3

3x=9 —-> x=3 EQUAL

3x-4+4=5+4 —-> 3x=9 —-> x=3 EQUAL

x-4=2 —-> x=6 NOT EQUAL

x=9 NOT EQUAL

-4=5-3x ——> -9=-3x ——> x=3 EQUAL

so it’s 3x=9, 3x-4+4=5+4, and -4=5-3x

What is the missing angle? Please provide an explanation.

irina [24]

Answer:

64 degrees

Step-by-step explanation:

Lets find the measure of the other angle in the other triangle with measures of 84 and 36.

Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:

84 + 36 = 120

180 - 120 = 60

So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90

90 - 60 = 30

So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.

86 + 30 = 116

180 - 116 = 64

So the missing angle has a measure of 64 degrees

Answer:

$\large\boxed{\dfrac{11}{4}x+8}$

Step-by-step explanation:

$\left(-\dfrac{11}{4}x+3\right)-2\left(-\dfrac{11}{4}x-\dfrac{5}{2}\right)\qquad\text{use the distributive property}\\\\=-\dfrac{11}{4}x+3+(-2)\left(-\dfrac{11}{4}x\right)+(-2)\left(-\dfrac{5}{2}\right)\\\\=-\dfrac{11}{4}x+3+\dfrac{22}{4}x+5\qquad\text{combine like terms}\\\\=\left(-\dfrac{11}{4}x+\dfrac{22}{4}x\right)+(3+5)\\\\=\dfrac{11}{4}x+8$
