Answer:
x=34, y=-28, z=-46
Step-by-step explanation:
because opposite angles of parallelograms are congruent: -3y-3=81 => y=-28. because internal angles of quadrilateral sum to 360°: 81+-3(-28)-3+3x-3-2z+7=360 => 3x-2z=194 => z=3/2x-97. because opposite angles of parallelograms are congruent: -2z+7=3x-3. substitute z=3/2x-97: -2(3/2x-97)+7=3x-3 => x=34. z=3/2(34)-97=-46

Answer:
1.9x+2(1.5)>30
Step-by-step explanation:
1.9(15)+2(1.5)
28.5+3
31.5 dollars
therefore the equation is grater than 30 dollars
Answer: x=8
Step-by-step explanation:
Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.
6x+13+4x-3=90 [combine like terms]
10x+10=90 [subtract both sides by 10]
10x=80 [divide both sides by 10]
x=8
Now, we know that x=8.
