Hey there!
Set up an equation. This would be 4+0.5x=12. You have to get x by itself, so subtract 4 on each side. You get 0.5x=8. Divide by 0.5 on each side to get x=16. Heidi purchased 16 tickets.
I hope this helps!
X=24
To find the value of x, you have to divide 48 by 2.
-4 < 4(6y - 12) - 2y
<em><u>Distributive property.</u></em>
-4 < 24y - 48 - 2y
<em><u>Combine like terms.</u></em>
-4 < 22y - 48
<em><u>Add 48 to both sides.</u></em>
44 < 22y
<em><u>Divide both sides by 22.</u></em>
2 < y
The value of y is greater than the value of 2.
Answer:
x = 16
Step-by-step explanation:
The diagram can be misleading because angle A does not correspond to angle F. Rather angle F corresponds to angle C.
In congruent triangles, corresponding angles have the same measure. The sum of angles is always 180°, so we have ...
... m∠A +m∠B +m∠C = 180°
... (3x+6)° +50° +(9x -68)° = 180°
... 12x -12 = 180 . . . . . divide by °, collect terms
... x -1 = 15 . . . . . . . . . .divide by the coefficient of x
... x = 16 . . . . . . . . . . . add 1

<em>Check</em>
m∠A = (3x+6)° = 54°
m∠C = (9x -68)° = 76°
The total of angles is 54° +50° +76° = 180°. . . . . as it should be
