Answer:
A. 81
Step-by-step explanation:
Combine fractions, that equals 2/5 in your exponent. Three to the 2/5 power is 81. So answer A.
105 × $8.72 = $915.60
$915.60 + $348 = $1,263.60
Mary paid $1,263.60 for the stock.
Look at the coordinates. They are both negative. (-5,-1)
Let me plot all the coordinates so you can see:
Joe= (-3,4)
Dan= (1,4)
Roy= (2,-3)
Lee= (-3,-4)
The only person with coordinates that are both negative is Lee.
"C" is the answer. Lee.
I hope this helps!

Answer:
x = 112°, y = 68°
Step-by-step explanation:
68° and y are corresponding angles and are congruent, then
y = 68°
x and y are adjacent angles and are corresponding ( sum to 180° ), then
x + y = 180°
x + 68° = 180° ( subtract 68° from both sides )
x = 112°
Answer:
pen = $1.20, pencil = $0.50
Step-by-step explanation:
let x = pen
let y = pencil
create system of equations:
3x + 6y = 6.60 [can be simplified to be x + 2y = 2.20]
5x + 8y = 10.00
substitution method:
x = 2.2 - 2y
5(2.2 - 2y) + 8y = 10
11 - 10y + 8y = 10
-2y = -1
y = 1/2
solve for 'x':
3x + 6(1/2) = 6.6
3x + 3 = 6.6
3x = 3.6
x = 1.2
