Answer:

The value of x is $59\°$

Step-by-step explanation:

we know that

The sum of the internal angles of a quadrilateral must be equal to $360\°$

$(2x+3)\°+(2x+3)\°+x\°+x\°=360\°$

solve for x

$2x+2x+x+x=360\°-6\°$

$6x=354\°$

$x=59\°$

360=x+x+(2x+3)+(2x+3)
we have 360=2x+2x+2x+6
360-6=6x
354=6x
x=354/6=59
x=59

Well, first, the equation that you are looking for is Y = MX + B. To find B, look at the first dot on the Y-axis. It starts at positive 3, so, you know your equation will end with +3. Next, to find MX, start at the either dot, and find the Rise/Run. In this particular equation, the rise is 1, and, the run is -2, because it's going backwards (negative line). Meaning, the line's equation would be, f( x )= -1/2x + 3.

K over x = w over v solve for x

Amiraneli [1.4K]

$\frac{k}{x}$ = $\frac{w}{v}$ Multiply both sides by v
 $\frac{kv}{x}$ = w Multiply both sides by x
kv = wx Divide both sides by w
 $\frac{kv}{w}$ = x Switch the sides to make it easier to read
x = $\frac{kv}{w}$

Ami'yan runs every day for exercise at a rate of 1 kilometer every 15 minutes. How many meters does he run in 1 hour? - Thank yo

Alona [7]

Answer:

The total distance covered in 1 hour is 4000 meters.

Step-by-step explanation:

The distance Ami'yan runs is 15 minutes = 1 kilometer

Using the unit formula,

The distance ran in 1 minute = $(\frac{1}{15} ) \textrm{Kilometer}$

Now, 1 hour = 60 minutes

⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)

= $60 \times \frac{1}{15} = 4$

So, the distance covered in 1 hour = 4 kilometer

1 kilometer = 1000 meters

⇒ 4 km = 4 x 1000 meters = 4000 m

Hence, the total distance covered in 1 hour = 4000 meters.
