morpeh [17]

Answer:

c+10+2c+c=220

Step by step Explanation:

Let, a= number of adult's tickets sold

s= number of senior's tickets sold

c= number of children's tickets sold

a=c+10

and, s=2c

Now, a+ s+ c=220

c+10+2c+c=220

4c=210

c=52.5

Note: If there were 222 tickets the answer will be 53

17. Classify Each Angle Pair then find the value of X

IRISSAK [1]

Given -

If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

To find -

m∠2.

Concept -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

Solution -

$\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}$
