Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129
Let x equal the number of adult tickets sold.
X + 3X=512
(I put 3x because we know the students sold 3 times as many).
Solve for X.
X+3X=512
4X=512
4X/4=512/4
X=128
You would have to divide $2.50 by $14.30 and you will get your answer
Answer:
v = 0.58
Step-by-step explanation:
-22 - 7v = -3(8v + 4)
Expand -3(8v + 4)
3 * 8v - 3 * 4
Simplify -3 * 8v -3 * 4
= -24v - 12
-22 - 7v = -24v - 12
Add 22 to both sides
-7v = -24v +10
Add 24v to both sides
17v = 10
