Answer:
I believe that Tony will have to work 16 or 17 hours to have enough money to buy the TV
Step-by-step explanation:
$276.99 - 135 = $141.99
$8.50 x 8 = $68
$8.50 x 16 = $136
$8.50 x 17 = $144.50
$8.50 x 33 = $280.50
$136 < $141.99 $144.50 > $141.99
$8.50 x 16 or $8.50 x 17
Check to see if the numbers are correct.
If they are you will have to make a choice.
I hope this helped. ☺
Composite
because it's factors are:
1, 3, 7, 21
k = 6
Solution:
p(x) = 2x^3 + 5x^2 - x - k
x + 2 = 0
x = -2
p(-2) = 2(-2)^3 + 5(-2)^2 - (-2) - k
0 = -16 + 20 + 2 - k
0 = 6 - k
Therefore, k = 6
OPTION (a) 6
PLZ MARK ME AS BRAINLIEST!!!
The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, and 360.
The argument is valid
The explanation will be given in the image, where we see all propositions and which contains the other, showing that the argument is valid.
240
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
