Step-by-step explanation:

=-3(3+7) - ( 4+3)

=-3.10-(4+3)

=-3.10-7

=-30-7

=-37

Answer:

Your final answer will be

−37

Step-by-step explanation:

(2−5)(3+7)−(4+3)

= −3(3+7)−(4+3)

= (−3)(10)−(4+3)

= −30−(4+3)

= −30−7

= −37

Is the following number irrational?
-8.7


Answers

Answer:

No.

Step-by-step explanation:

Rational numbers are any of the following:

Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...

Irrational numbers are thus defined as:

Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).

This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.

1 mile divided by 2 laps =

Answers

The answer is 800 meters
1 mile is 1600 meters or four laps
So if you divide 1600 by 2 you get 800 meters

There are 4 laps in one mile, therefore, "1 mile divided by 2 laps" = 2.

What is division?

Division is the process of dividing a number by a given number.

Given, the statement "1 mile divided by 2 laps".

The statement written in mathematical form is:

(1 mile)/2 laps

There are 4 laps in one mile, therefore, substitute 1 mile = 4 laps into the above equation:
(4 laps)/2 laps

= 2

Hence, "1 mile divided by 2 laps" = 2.

Answers

Answer:

x =-4

Step-by-step explanation:

3x − 7 = −19

Add 7 to each side

3x − 7+7 = −19+7

3x = -12

Divide by 3

3x/3 = -12/3

x =-4

Work it backwards: -19+7=-12 so that means we do -12/3 next and it equals -4, so your answer is x=-4

E. Angle ABC is congruent to angle A'B'C'
F. Segment BC is congruent to segment B'C'
G. Segment BQ is congruent to segment C'Q.
H.Segment AQ is congruent to segment A'Q.

Answers

Answer:

The correct options are;

D. Triangles ABC and A'B'C' are congruent

E. Angle ABC is congruent to angle A'B'C'

F. Segment BC is congruent to segment B'C'

H. Segment AQ is congruent to segment A'Q'

Step-by-step explanation:

The given information are;

The angle of rotation of triangle ABC = 60°

Therefore, given that a rotation of a geometric figure about a point on the coordinate plane is a form of rigid transformation, we have;

1) The length of the sides of the figure of the preimage and the image are congruent

Therefore;

BC ≅ B'C'

2) The angles formed by the sides of the preimage are congruent to the angles formed by the corresponding sides of the image

Therefore;

∠ABC ≅ ∠A'B'C'

3) The distances of the points on the figure of the preimage from the coordinates of the point of rotation are equal to the distances of the points on the figure of the image from the coordinates of the point of rotation

Therefore;

Segment AQ ≅ A'Q'.

b) 3x/2=6​

Answers

Answer:

A) X = 12

B) X = 4

Step-by-step explanation:

For both equations, the first step is the same. You must isolate x.

A) 2x/3 = 8

Multiply each side by 3 to get rid of the fraction.

2x = 24

Divide by 2.

x = 12

B) 3x/2 = 6

Multiply each side by 2 to get rid of the fraction.

3x = 12

Divide by 3.

x = 4

One week, Brooklyn earned $179.30 at her job when she worked for 11 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $244.50?

Answers

Answer:

Brooklyn would get paid 16.30 hourly. So she will have to work 15 hours the next week to earn 244.50.

Step-by-step explanation:

Divide 179.30 by 11 and you would get 16.30 which is her hourly wage. Then you divide 244.50 by 16.30 to see how many hours she would have to work to earn 244.50.

Answer:

15 Hours

Step-by-step explanation:

179.30 / 11 = $16.3 an hour

244.5 / 16.3 = 15 hours

Solve the y for the equation 5x-2y=10

Answers

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5

Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5

  8

Step-by-step explanation:

The first division was ...

  a/-2 = 8

Multiplying by -2, we have ...

  a = (-2)(8) = -16

__

The second division was ...

  8/b = -4

Multiplying by b/-4, we have ...

  8/-4 = b = -2

Then the quotient of interest is ...

  a/b = (-16)/(-2)

  a/b = 8
