Answer:

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

Step-by-step explanation:

Switch sides

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

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]

Then simplify

[tex]3d=2M[/tex]

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

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

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.

Answer:

The above statement is True.

Step-by-step explanation:

Congruent angles are two or more angles that have the same measure. In simple words, they have the same number of degrees.

[tex] \sf{ \red{ \underline{Solution - }}} \\ [/tex]

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

Here I have used this formulae in your all questions.

The standard quadratic equation is ax²+bx+c = 0

Answer: what graph?

Step-by-step explanation:

3 + 0.75x = 5.25 - 0.25x

0.75x = 2.25 - 0.25x

x = 2.25

3 + 0.75(2.25) = 5.25 - 0.25(2.25)

3 + 1.6875 = 5.25 - 0.5625

4.6875 = 4.6875

They are equal

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

Answer:

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Take any 2 points on the line. Use the slope formula ([tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex])

For this example, I will use:

20, 30 and 60, 60.

[tex]m=\frac{30-60 }{20-60 }= \frac{3}{4}[/tex]

Answer:

Neither

Step-by-step explanation:

180-59-61 = 60 degrees

It is an scalene triangle = no equal angles

Step-by-step explanation:

option C is correct ( neither).

because the other side is 180-61-59 = 60.

therefore, the three angles are different, and it's a scalene triangle.

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.

Student tickets: 287

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)

842 - 2y + 5y = 1244

3y = 1244 - 842

y = 402/3
