Only when any equation you find among those numbers can be simplified into one of the four main equations, wich means you only have four different true statements, and lots of equivalences<span>.</span>

For example, 
</span><span>20 + 20 = 40
40 - 20 = 20
40 = 20 + 20
20 = 40 - 20.
</span>As the two addends are the same, so <span>there would be only four different equations for a set of math mountain numbers.</span>

kakasveta [241]

<em>The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park</em>

Answer:

Width = 2\ km

Step-by-step explanation:

Given

Length = \frac{3}{8}km

Area = \frac{3}{4}km^2

Required

Determine the Width

For a rectangle:

Area = Length * Width

Substitute for Area and Length

\frac{3}{4} = \frac{3}{8} * Width

Multiply both sides by \frac{8}{3}

\frac{8}{3} * \frac{3}{4} = \frac{3}{8} * \frac{8}{3}* Width

\frac{8}{3} * \frac{3}{4} =  Width

\frac{24}{12} = Width

2 = Width

Width = 2\ km

An angle measures 30° more than the measure of its supplementary angle. What is the measure of each angle?
yarga [219]

Hi there!
\boxed{\angle A = 75^o, \angle B = 105^o}

Let there be two angles, ∠A and ∠B, that are supplementary to each other. Therefore:

∠A + ∠B = 180°

We can assign ∠B to be the greater angle. Assume ∠A has a measure of x°.

∠A = x°

∠B = x° + 30°

The sum is equal to 180°, so:

x° + (x° + 30°) = 180°

Solve for x°.

2x° + 30° = 180°

2x° = 150°

x° = 75°

Thus, ∠A = 75°.

Since ∠B is 30°, greater:
∠B = 75° + 30° = 105°.

What is the value of x in 145.95-2x=-4.05?
kotykmax [81]
145.95 - 2x = -4.05
subtract -145.95 from both side of the equation
-2x = -4.05 - 145.95
-2x = -150
Divide both sides by -2
-2x/2 = -150/2

x = 75
Final answer

Hope this helps!!!!
