Let D represent the cost of the desk and T represent the tax paid.
Given,the cost of the desk plus the tax equals $131.44, so equation becomes
D + T = 131.44 ...(1)
As given, tax T equals 1/16 times the cost of the desk less 0.31 dollars, so equation becomes T = (1/16)D - 0.31
Now substituting the right side of this equation for T into equation (1 )for the total price
, so the first equation becomes:
D + (1/16)D - 0.31 = 131.44
Now adding 0.31 to both sides we get:
D + (1/16)D = 131.75
Since D is equivalent to (16/16)D we can substitute that for D and we get:
(16/16)D + (1/16)D = 131.75
= (17/16)D = 131.75
= 17D = 131.75*16
17D = 2108
D = 124
Hence, the cost of the desk is $124
So, Option D = $124.00 is correct

Answer:
A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Step-by-step explanation:
Given :
Velocity of bullet = 3510 km/hr
Distance traveled = 100m
Converting distance in meter to kilometer :
(100 / 1000) km = 0.1 km
Recall :
Speed = Distance /time
Time taken = Distance / speed
Therefore,
Time taken = Distance / speed
Time taken = 0.1 km / 3510 km/hr
Time = 2.849 * 10^-5 hour
Answer:
26 meters
Step-by-step explanation:
a = bh
416 = 16h
Divide both sides by 16
h = 26
26 meters
Answer:
x = 20
Step-by-step explanation:
<em>Each line creates a 180° angle on each side of it. Since these lines intersect, they have congruent angles. This means that these two quantities can be set equal to each other.</em>
3x + 50 = 6x - 10
<em>Solve by combining like-terms and isolating </em><em>x</em><em>. Move the </em><em>3x</em><em> to the right by subtracting it from both sides.</em>
50 = 3x - 10
<em>Move the </em><em>10</em><em> to the left by adding it to both sides.</em>
60 = 3x
<em>Divide the </em><em>3</em><em> from both sides to isolate the </em><em>x.</em>
x = 20
<em>Furthermore, this can be checked by plugging in </em><em>20</em><em> to </em><em>x</em><em> and seeing if the expression is true.</em>
3(20) + 50 = 6(20) - 10
110 = 110
