If x = 3, then y = |3-3| + |3+2| - |3-5|

Thus, after adding and subtracting within the absolute quantity groupings, you have

y = |0| + |5| - |-2|

Absolute value can be defined as distance from zero on the number line. Thus,

y = 0 + 5 - 2

Complete the equation bu adding/subtracting.

y = -3

This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent

so we solve like this

$x+3=2x-5$

subtract -3 on each side one is canceled since its equal to zero

and other is -3-5= -8

$x=3x-8$

now subtract -3 on each side

-3x-x is -4 so,

-4x=8

divide its equal to 2

X=2

Hope it helps! have an awesome day you should probably study the properties of parallelogram

viva [34]

Answer:

hotogs=$1.50 hamburgers=$1

Step-by-step explanation:

h=hotdog b=hamburger

7h+4b=13

4h+7b=14.5

(7h+4b=13)-4b

4h+7b=14.5

h=-0.57b+1.86

4h+7b=14.5

∠A and \angle B∠B are supplementary angles. If m\angle A=(x-16)^{\circ}∠A=(x−16) ∘ and m\angle B=(3x+28)^{\circ}∠B=(3x+28) ∘ , t

GalinKa [24]

Answer:

∠A = 26°

Step-by-step explanation:

Supplementary angles total 180°.

∠A +∠B = 180°

(x -16)° +(3x +28)° = 180°

4x° + 12° = 180°

x° +3° = 45°

x° = 42°

∠A = (x -16)° = 42° -16°

∠A = 26°
