1) The sum of
Which system of equations will determine the numbers?
C)
B)
x + y = 104
y = 2x - 1
A)
x + y = 104
y = 1 - 2x
x - y = 104
y = 2x - 1
2)
Matt and Ming are selling fruit for a school fundraiser. Customers can buy small boxes of
oranges and large boxes of oranges. Matt sold 3 small boxes of oranges and 14 large boxes
for a total of $203. Ming sold 11 small boxes and 11 large boxes for a total of $220. Which
system of equations will determine the cost of each of one small box of oranges and one large
box of oranges.
C)
B)
x + y = 220
3x + 14y = 203
3x + 14y = 203
11x + 11y = 220
A) x + y = 203
11x + 11y = 220
3)
Beth bought 15 tickets to a movie, where adult tickets cost $6 and senior citizen tickets cost $4. She
spent a total of $76. Which system of equations will determine the number of adult tickets, a, and the
number of senior citizen tickets, s, Beth purchased?

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

          72     -     432 - 3 = -363

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
