Answer: 360

Step-by-step explanation:

If you double 18 and then multiply by 10 will be 360.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ 18 x 20

The product of the numbers 18 and 20 will be 360.

If you double 18 and multiply the number by 10 will be

2(18) x 10 = 36 x 10 = 360

If you double 18 and then multiply by 10 will be 360.

[tex]d=\frac{2M}{3}[/tex]

Step-by-step explanation:

Switch sides

Multiply both sides by 2 to remove the fraction

[tex]2\cdot \frac{1}{2}\left(d\cdot \:1+d\cdot \:2\right)=2M[/tex]

Answer:

11 feet

Step-by-step explanation:

The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.

We have,

The absolute value equation representing the height restrictions for the Swan Ride would be:

| h - 2 | = 3 - h

To solve this equation:

Solving this equation gives:

For height - 2 ≥ 0:

height - 2 = height - 3

-2 = -3 (no solution in this case)

For height - 2 < 0:

-(height - 2) = height - 3

-height + 2 = height - 3

2 + 3 = height + height

5 = 2 * height

height = 5 / 2

height = 2.5 feet

Thus,

The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.

Let the height of rectangle be = x,

Area of rectangle = base × height

so, there are two cases now,

Case - 1 :

here, value of x (length) is negative, measure of length can't be negative, so length is not equal to -4/3

Case - 2 :

here, value of x = 4, and satisfys the condition so

The rectangle's height is 4 inches and the rectangle's base is also 4 inches.

Let's assume the height of the rectangle is 'h' inches.

According to the given information, the base of the rectangle is 8 inches shorter than three times its height. This can be expressed as:

Base = 3h - 8

The area of a rectangle is given by the formula:

Area = Length * Width

In this case, the area is given as 16 square inches. We can set up the following equation:

16 = h * (3h - 8)

Expanding the equation:

[tex]16 = 3h^2 - 8h[/tex]

Setting the equation equal to zero:

[tex]3h^2 - 8h - 16 = 0[/tex]

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's solve it using the quadratic formula:

[tex]h = (-b \± \sqrt{b^2 - 4ac}) / (2a)[/tex]

For this equation, a = 3, b = -8, and c = -16. Plugging in the values:

[tex]h = (-(-8) \± \sqrt{(-8)^2 - 4 * 3 * (-16)}) / (2 * 3)\\\\h = (8 \± \sqrt{64 + 192}) / 6\\\\h = (8 \± \sqrt{256}) / 6\\\\h = (8 \± 16) / 6[/tex]

We have two possible values for h:

h₁ = (8 + 16) / 6 = 4

h₂ = (8 - 16) / 6 = -1

Since the height of a rectangle cannot be negative, we can discard the value h₂ = -1.

Therefore, the rectangle's height is 4 inches.

Now, we can find the base of the rectangle:

Base = 3h - 8

Base = 3 * 4 - 8

Base = 12 - 8

Base = 4

Therefore, the rectangle's base is also 4 inches.

Answer:

C

Step-by-step explanation:

Can't be B or D because the slope is negative but B and D have positive slopes. It's not A because slope is y2-y1/x2-x1. Take points (0,8) and (6,5) to plug into equation.

5-8/6-0= -3/6=-1/2

Therefore the answer is C since the y-intercept is 8 and the slope is -1/2

Adult tickets: 134

Step-by-step explanation:

Students: x

Adults: y

a) x + y = 421

b) 2x + 5y = 1,244

a) x = 421 - y

b) 2 (421 - y) + 5y = 1,244 (substitution)

Given equation is 1/(x+2) - 1/(x-2) = 1

=> [(x-2)-(x+2)]/(x+2)(x-2) = 1

=> (x-2-x-2)/(x²-4) = 1

=> (-2-2)/(x²-4) = 1

=> -4/(x²-4) = 1

=> x²-4 = -4

=> x²-4+4 = 0

=> x² +0 = 0

=> x² = 0

The standard form is x² = 0 or x²+0x+0 = 0

Answer:

b1= 2A/h - b2

Step-by-step explanation:

You have to multiply each side by 2, then divide each side by h. after that you subtract b1 from both sides and then you will get your answer.

Answer:

b1 = 2A / h - b2

Step-by-step explanation:

A = h(b1 + b2) / 2

[cross multiply]

h(b1 + b2) = A × 2

b1h + b2h = 2A

[divide both sides of the equation by h]

b1h / h + b2h / h = 2A / h

b1 + b2 = 2A / h

[make b1 the subject of the formula]

b1 = 2A / h - b2
