Fetures are x and y
x+y=12

23.99x+120.84y=675.28

x+y=12
multiply by -23.99 and add to other equation

-23.99x-23.99y=-287.88
<u>23.99x+120.84y=675.28 +</u>
0x+96.85y=387.4

96.85y=387.4
divde both sides by 96.85
y=4

sub back

x+y=12
x+4=12
minus 4
x=8


8 of the features costing $23.99
4 of the features costing $120.84

The area of a trapezoid is 144 square inches. if the height is 12 inches, find the length of the median.
deff fn [24]

Answer: 12 inches

Step-by-step explanation: In this problem, since we're asked to find the length of the median, let's use our formula for the area of a trapezoid that involves the median which is shown below.

Area = median · height

We know that the area is 144 and the height is 9 so we can set up the equation 144 = M · 12. Now to solve for <em>m</em>, we divide both sides of the equation by 12 and we find that 12 = M.

So the length of the median of the trapezoid is 12 inches.

ivanzaharov [21]
Total amount of cash the student earns per hour is $7.5, let the time taken to earn $200 be h, thus the inequality representing this will be:
7.5h≤200
thus
h≤80/3
writing in whole  numbers we shall have:
h≤27
