If you mean the system between the two then comes (x;y)=(5;3) otherwise if solved individually they are enough to make the common denominator

You can spend up to $35 on a shopping trip.
VMariaS [17]
A. 35 greater than or equal to 14 + x
    35 - 14 = 21
    x = $21
b. If the shirt is 30% off it would cost $9.80
    14 x 0.3 = 4.2
    14 - 4.2 = 9.8
    35 is greater than or equal to 9.80 + x
    35 - 9.8 = 25.2
    x = $25.20
    This changes the inequality by making x greater than it was in part a
c. Yes, you do have enough money to buy the shirt that is on sale and a pair of pants. x is the amount that you have left to spend after you buy the shirt that is on sale. 25.20 is greater than the cost of the pants.

A fraction reduces to 36. If its denominator is 6x^5, what it's its numerator?
earnstyle [38]
The answer is B because you will  cancel the x^5 part on top and bottom and the numerator left 6^3 and denominator left 6
6^3=216divid by 6 you will get 36

Part A) Find BC, the distance from Tower 2 to the plane, to the nearest foot.

in the triangle ACD
sin16=CD/(7600+BD)--------> CD=sin16*(7600+BD)---------> equation 1 

in the triangle BCD
sin24=CD/BD-----------> CD=sin24*BD---------------> equation 2
equation 1=equation 2
sin16*(7600+BD)=sin24*BD-----> sin16*7600+sin16*BD=sin24*BD
sin24*BD-sin16*BD=sin16*7600----> BD=[sin16*7600]/[sin24-sin16]
BD=15979 ft

in the triangle BCD
cos24=BD/BC---------> BC=BD/cos24-------> 15979/cos24-------> 17491
BC=17491 ft

the answer part 1) BC is 17491 ft

Part 2) Find CD, the height of the plane from the ground, to the nearest foot.

CD=sin24*BD        ( remember equation 2)
BD=15979 ft
CD=sin24*15979 -----------> CD=6499 ft

the answer part 2)  CD is 6499 ft
