Answer:

(2x + 40) - 2

(x ÷ 5) - 14

(x ÷ 2) - 18

(x + 3) + 9

3x + 12

(x ÷ 2 + 3) + 12

4 * 2x or 8x

(x ÷ 3) - 5

3x + 5

6x - 13

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal. or

A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.

Can anyone please help me this? stuck with this problem for hours
Kipish [7]

Answer:

P=0.61 or 61%

Step-by-step explanation:

If we pick a random point within the circle, it can fall in the white area or in the pink area. Since the sum of both areas makes the sample space or the total area of the circle, we can compute the probabilities according to the ratio of the areas with respect to the total area, that is:

\text {Probability of falling in the white area} = \frac{\text{White area}}{\text{Circle area}}

The area of the circle is  

A_c=\pi r^2

The area of both the triangles is

A_t=2*\frac{bh}{2}

Where r=4 cm, b=3 cm, h= (4+2.5) cm = 6.5 cm

Then we have:

A_c=\pi 4^2=16\pi \ cm^2=50.27\ cm^2

A_t=19.5\ cm^2

The white area is obtained by subtracting both areas

A_w=A_c-A_t=50.27-19.5=30.77\ cm^2

So the probability is

P=\frac{30.77}{50.27}=0.61

The area of a rectangle is 108 m2 and its diagonal is 15 m. Find
Andre45 [30]

Answer:

47.6m.

Step by step solution:

Perimeter of a triangle = base + 2 . length____(1)

Area of a triangle = 1/2 . base . diagonal

108 = 1/2 . base . 15

multiplying both sides by 2:

216 = 15 . base

dividing both sides by 15:

base = 14.4m

But the diagonal divides the triangle into two

right angle triangles each with the same length (hypotenuse),base and diagonal(height).

Taking one right angle triangle:

And using pythagoras theorem;

length² = base² + diagonal ²

length² = 7.2² + 15²

Note: Base of each right angle triangle is 7.2 which would sum up to be 14.4 the base of the full triangle.

length² = 276.84

taking the square root of both sides:

length = 16.6m

Putting the values of the base and length into equation (1).

Perimeter of the triangle = 14.4 + 2 . 16.6

Note: We are dealing with the whole triangle

now hence the base is 14.4m.

Perimeter of the triangle = 14.4 + 33.2 = 47.6m.
