5x + 3y = 7> (4) 5x + (4) 3y = (4) 7
4x + 5y = 3> (-5) 4x + (-5) 5y = (-5) 3
20y + 12y = 28
-20x -25y = -15
(X's cross out) 12y - 25y = 28 -15
-13y = 13
Y = -1
(Plug in for y) 5x + 3(-1) = 7
5x -3 =7 (add 3 to 7)
5x = 10 (divide by 5)
X= 2
Ordered Pair= (2, -1)

Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
Answer: <span>P(Female | Type B) < P(Female or Type B)
</span>
In this question, there is 85 Type A female and 12 type B female which makes a total of 97 female. There is also 38 male Type B from a total of 113 male. Then the probability would be:
female type B = type B female/ total female
female type B = 12/97
Female or Type B= Female + type B male/ total
Female or Type B= 97+38/ 97+113= 135/ 210
It should be clear that <span>P(Female | Type B) < P(Female or Type B)
