Answer:

28 = x

Step-by-step explanation:

62 =  angle BAC  since they are vertical angles

angle ABC is a right angle since KL is perpendicular to FG

Adding the angles in triangle ABC

BAC + ABC + BCA = 180

62 + 90 + BCA = 180

152 + BCA = 180

BCA = 180-152

BCA = 28

BCA = x since they are vertical angles

28 = x

500 - 400 = 100

100-60 = 40

Answer:

Money with Peter = $ 40

Step-by-step explanation:

Let 'x' be the money left with Peter

Money left with Peter after fixing his car = 1000 - 500 = 500

500 is divided into 5 equal parts and 4 parts he gave away. 500 - 400 = 100

x = (1000 - 500) - 400 - 60

= 500 - 400 - 60

= 100 - 60

x =$  40

Answer: Standard Deviation.

Step-by-step explanation:

DescriptionIn insights, the standard deviation is a proportion of the measure of variety or scattering of a lot of qualities. A low standard deviation demonstrates that the qualities will in general be near the mean of the set, while an elevated expectation deviation shows that the qualities are spread out over a more extensive territory.

Answer:

3 : 1

Step-by-step explanation:

[tex] \huge7.5 : 2.5 = \frac{7.5}{2.5} = \frac{3}{1} = 3 : 1 [/tex]

The equivalent ratio to 7.5 : 2.5 is given by dividing both elements by 2.5, the ratio is: 3 : 1

Remember that in a ratio A : B we can always multiply or divide both numbers by the same number, and the ratio does not change.

So, for the ratio:

7.5 : 2.5

To be in the form of:

n : 1

We can just divide both elements by 2.5, so we get:

7.5/2.5 = 3

2.5/2.5 = 1

Then we conclude that:

7.5 : 2.5 is equivalent to 3 : 1

Answer:

  x = 28/(3y -15)

Step-by-step explanation:

Put the x-terms on the same side of the equal sign and everything else on the other side. Divide by the coefficient of x.

  3xy -28 = 15x . . . . . . given

  -28 = 15x -3xy . . . . . subtract 3xy

  -28 = x(15 -3y) . . . . . factor out x

  -28/(15 -3y) = x . . . . . . divide by the coefficient of x

We prefer to have a positive sign where possible, so we can multiply this by -1/-1 to get ...

Answer:  multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive.

Step-by-step explanation:

The result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

In mathematics, adding a negative number and a positive number involves combining two quantities with opposite signs. When we add a negative number and a positive number, we can think of it as "subtracting the absolute value of the negative number from the positive number."

For example, if we have -3 + 5, we can rewrite it as 5 - 3, which equals 2. In this case, we are subtracting the absolute value of the negative number (3) from the positive number (5).

Similarly, if we have -7 + 2, we can rewrite it as 2 - 7, which equals -5. In this case, we are subtracting the absolute value of the negative number (7) from the positive number (2), but since the negative number has a larger absolute value, the result is negative.

So, the result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

Answer:

40b

Step-by-step explanation:

25 + 15 = 40

Answer:

40b

Step-by-step explanation:

We are given the expression:

25b+15b

and asked to simplify.

To simplify, we must combine like terms. Let's analyze the terms.

25b ⇒ has a variable "b"

15b ⇒ also has a variable "b"

The like terms in this expression are the terms with a variable, b.

To combine like terms, add the coefficients and leave a b on the end.

(25+15)*b

(40)*b

40b

The expression 25b+15b simplified is 40b.

=====================================================

Explanation:

The blue parent function has a positive coefficient of 1. The purple g(x) function is a reflection of f(x) over the x axis, so everything is now negative. The coefficient must be negative as well.

But the answer is simply not g(x) = -x^2 because plugging x = 3 does not lead to y = -6 as the point (3,-6) shows.

Let's say the coefficient is k for now. So we have y = kx^2

Plug in x = 3 and y = -6. Solve for k

y = kx^2

-6 = k(3)^2

-6 = k*9

9k = -6

k = -6/9

k = -2/3

So we update y = kx^2 into y = (-2/3)x^2

Meaning that g(x) = (-2/3)x^2 is the equation of the purple curve.

Plug x = 3 into g(x) to find that

g(x) = (-2/3)x^2

g(3) = (-2/3)(3)^2

g(3) = (-2/3)(9)

g(3) = -6

which is the output we want, so this confirms we have the correct coefficient.

Answer:

y=(-2/3)x^2

I'll answer this question using the following instances;

[tex]1.\ \frac{x}{3} = 1[/tex]

[tex]2.\ 3x = 1[/tex]

For the first expression, we multiply both sides by 3

[tex]3 * \frac{x}{3} = 1 * 3[/tex]

[tex]x = 1 * 3[/tex]

[tex]x = 3[/tex]

For the second; divide both sides by 2

[tex]\frac{3x}{3} = \frac{1}{3}[/tex]

[tex]x = \frac{1}{3}[/tex]

The property applied in both expressions is the identity property of multiplication
