Answer:
-7/3 & 5/2
Step-by-step explanation:
3x +7 = 0
3x = -7
x = -7/3
2x-5=0
2x = 5
X = 5/2
Answer:
$12
Step-by-step explanation:
Since she has $16 left, this means she spent $84. ($100-$16=$84)

Answer:
C. The 4 columns of UQ list the total costs for materials, labor, and overhead used to manufacture products B and C during the 4 quarters of the year.
Step-by-step explanation:

is a vector in the set of real numbers
that lists the output (measured in dollars) of products B and C manufactured during the first quarter of the year.
Therefore:

Therefore, UQ has 4 columns and 3 rows.
The 4 columns of UQ list the total costs for materials(Row 1), labor(Row 2), and overhead(Row 3) used to manufacture products B and C during the 4 quarters of the year.
Answer:
46
Step-by-step explanation:
The missing length is 10-4 = 6
Therefore perimeter = 5 + 6 + 8+ 4+13 +10
=46
There are
ways of drawing a 4-card hand, where

is the so-called binomial coefficient.
There are 13 different card values, of which we want the hand to represent 4 values, so there are
ways of meeting this requirement.
For each card value, there are 4 choices of suit, of which we only pick 1, so there are
ways of picking a card of any given value. We draw 4 cards from the deck, so there are
possible hands in which each card has a different value.
Then there are
total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is
