14v-10=14v
14v-14v=10
the Value of v don't get because when 14v-14v is equal to zero
Answer:
x = 10
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, thus
∠ A + ∠ B = 180, substitute values
9x + 8 + 8x + 2 = 180, that is
17x + 10 = 180 ( subtract 10 from both sides )
17x = 170 ( divide both sides by 17 )
x = 10
The variable <em>x </em>is equal to 0.5
Answer:
369
Step-by-step explanation:
Answer: Cost of tickets for adults = $22
Cost of tickets for children = $15
Total number of tickets sold = 732
Total receipts = $12,912
Let x be number of adult ticket's sold and y be the number of child ticket's sold.
Therefore, we have:
--------------- equation 1

Also, we have:

Now, let's substitute the value of x:






Now, let's substitute the value of y=456 in equation 1, we have:



Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
