Answer: -3

Step-by-step explanation:

Let's solve your equation step-by-step.

19+12k=−k−20

Step 1: Simplify both sides of the equation.

19+12k=−k−20

19+12k=−k+−20

12k+19=−k−20

Step 2: Add k to both sides.

12k+19+k=−k−20+k

13k+19=−20

Step 3: Subtract 19 from both sides.

13k+19−19=−20−19

13k=−39

Step 4: Divide both sides by 13.

13k /13 =  −39/13

Quinn is flying a kite. The angle of elevation formed by the kite string and the ground is 40°, and the kite string forms a stra
emmasim [6.3K]

The distance between the ground and the kite to the nearest foot is 64 ft.

<h3>What is a right angle triangle?</h3>

A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms a right angle triangle.

Hence,

The length of the kite string is the hypotenuse side of the triangle formed.

The height between the ground and the kite is the opposite side of the triangle formed.

Therefore, using trigonometric ratio,

sin 40 = opposite / hypotenuse

sin 40 = h / 100

cross multiply

h = 100 sin 40

h = 100 × 0.64278760968

h = 64.2787609687

h = 64 ft

Therefore, the distance between the ground and the kite to the nearest foot is 64 ft.

4 less than half a number is equal to 2 more than the number
xxMikexx [17]

Answer:

-12

Step-by-step explanation:

Let that number be x. We can build an equation, and solve for x.

4 less than half of x is x/2-4.

2 more than x is x+2.

We are given that the two quantities are equal, so we have that x/2-4=x+2.

Adding 4 to both sides gives x/2=x+6.

Multiplying both sides by 2 gives x=2(x+6)=2x+12.

Subtracting 2x from both sides gives -x=12.

Multiplying both sides by -1 gives x=-12.

So, the number is \boxed{-12} and we're done!

The check is left as an exercise to the reader.
