Answer:

a = \frac{1}{3}

Step-by-step explanation:

4a -16 = a - 15

both left and right -a

then

4a - 16 -a = a - 15 -a

then

4a -a -16 = a -a -15

then

3a -16 = -15

both left and right + 16

then

3a -16 + 16 = -15 + 16

then

3a = 1

both left and right ÷3

then

3a ÷ 3 =1 ÷ 3

then

a = \frac{1}{3}

NeTakaya

Answer:

Since, an airplane descended 4,000 feet before landing.

Now, we have to determine the integer which represents the number of feet, the airplane was above the ground before its descent.

Before the descent, airplane was at the height of 4,000 feet.

And the distance above the ground is represented by the positive integers and distance below the ground is represented by the negative integers.

Since, 4,000 feet is the distance of airplane above the ground.

So, the airplane was +4,000 feet above the ground before its descent.

Hello! Please ignore the stuff I already wrote, can someone help me find x and y?
DanielleElmas [232]

Answer:

x=12

y=12\sqrt{3}

Step-by-step explanation:

Hey There!

to solve this problem we need to use the 30 - 60 - 90 triangle rule

So you are correct on x because the hypotenuse is 2x

24/2=12

y would equal 12\sqrt{3}

as you could see in the image down below
