Answer:

W=7 and L=11

Step-by-step explanation:

We have two unknowns so we must create two equations.

First the problem states that  length of a rectangle is 10 yd less than three times the width so: L= 3w-10

Next we are given the area so: L X W = 77

Then solve for the variable algebraically. It is just a system of equations.

3W^2 - 10W - 77 = 0

(3W + 11)(W - 7) = 0

W = -11/3 and/or W=7

Discard the negative solution as the width of the rectangle cannot be less then 0.

So W=7

Plug that into the first equation.

3(7)-10= 11 so L=11

igor_vitrenko [27]

Answer:

The will play the song at the same time by 4:12 pm

Step-by-step explanation:

here, we want to know the time both radio station will play the song after 3pm.

Mathematically to get this, we shall need to find the lcm of both 18 and 24. LCM stands for the lowest common multiple of both.

The lowest common multiple of both is 72.

This means that after 72 minutes, they will both play the song

So the time then would be;

72 + 3 = 4 : 12 pm
