Answer:
815
Step-by-step explanation:
First you put the value of x from the table into the formula provided.
<em>y = -670 + 33(x) </em><= plug in the x value from the table
<em>y = -670 + 33(45)</em> <= multiply 33 * 45
<em>y = -670 + 1485</em> <= add the two terms (which you will subtract because one is positive and one is negative.
<em>y = 815</em>
P = price of tickets
8.50p = 42.50
you then divide 8.50 on both sides
8.50p = 42.50
——— ———
8.50 8.50
p = 5
meaning Allison bought 5 tickets in total.
Answer: (use distributive property then add the like terms)
3(2p + 4) - (3p - 4) = 43
6p + 12 - 3p - 4 = 43
3p - 8 = 43
You can use cross-products to solve this problem. For instance, this expression would be written as 5(8)= 7(-x), or 40= -7x. What you'd do then is simplify the expression by dividing both sides of the equation by the coefficient of x, such that you'd isolate x and have the value of x.
