First, you should probably solve the equation.

3 x 45 = 135

So n = 135.

For a division problem to work, the bigger number has to come first, so there are two possible answers.

135 / 45 = 3
135 / 3 = 45

Now all you need to do is put the n back in.

n / 45 = 3
n / 3 = 45

SOMEONE PLEASE HELLPPPP

Answer:

93.39

Step-by-step explanation:

So the sum of exterior angles of the convex octagon is: 360 degrees

This means if we add all the equations that represent each angle, we can set it equal to 360 and solve for x

$(x+14) + (2x-3) + (3x+8) + (3x+16) + (2x-17) + (3x-4) + (3x-12) + (6x)$

Group like terms

$(x+2x+3x+3x+2x+3x+3x+6x) + (14-3+8+16-17-4-12)$

Add like terms

$23x+2$

Now let's set the sum of exterior angles to 360

$23x+2 = 360$

Subtract 2 from both sides

$23x=358$

Divide both sides by 23

$x\approx 15.565$

So by looking at all these, it appears that 6x is the highest value, given that x is positive. The way I estimated, is approximately 15.5, whenever I saw an equation like x+14, I estimated it's about 2x, since 14 is not exactly, but close to 15.5. I did this with each polynomial given. You could also manually check each one

Original equation

Subsitute

6(15.565)

Simplify

$93.39$

As an estimation we are told 5 miles is 8 km. Convert 2.5 miles to km.

Digiron [165]

Answer:

$4km$

Step-by-step explanation:

In order to find the answer to this question you must simply divide.

$5m=8km$

$2.5m=4km$

$8\div2=4$

$5=2.5+2.5$

$=4km$

Hope this helps

Answer: 37.05m^2

Step-by-step explanation:

Area of shaded region = Area of rectangle - non shaded region (the middle shapes)

Rectangle = 13.7 x 14.4 = 197.28m^2

Left half circle: 3.14 x 6.3^2 = 124.6266m^2

Right half circle: 3.14 x 2.8^2 = 24.6176m^2

Square: 3.3^2 = 10.98 m^2

197.28 - ( 124.63 + 24.62 +10.98 ) = 37.05 m^2
