Step-by-step explanation:

Let x, and x+1 be the consecutive numbers.

[tex]x + (x + 1) = 37[/tex]

[tex]2x + 1 = 37[/tex]

[tex]2x = 36[/tex]

[tex]x = 18[/tex]

Plug in 18 for x+1,

[tex]18 + 1 = 19[/tex]

So the numbers is 18,19

Answer:

18 and 19

Step-by-step explanation:

if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1

The equation x + x + 1 = 37

To solve this equation subtract 1 from both sides as one does in algebra.

x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1

Now you have the equation x + x = 36

This can rewrite this as 2x = 36        2x means 2 times the value of x

To solve this part of the equation divide both sides by 2

2x / 2 = 36 / 2

x = 18

The next consecutive number x + 1 = 19, (18) + 1 = 19

check this by adding. 18 + 19 = 37.

write an equation using x and y to represent the hanger.

Answers

Answer:

Step-by-step explanation:

Givens

The triangle is x

The square is y

Left side

x + 3y is the weight

Right side

4x + y is the weight.

The weights are equal because the hanger is balanced.

Balance equation

x + 3y = 4x + y                 Subtract x from both sides

x-x + 3y = 4x-x + y           Combine

3y = 3x + y                       Subtract y from both sides

3y - y = 3x + y - y             Combine

2y = 3x

Answer

2y = 3x

Answer:

  x +3y = 4x +y

Step-by-step explanation:

A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.

__

left side

The left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...

  x + 3y

right side

The four triangles and 1 square on the right can have their total weight represented as ...

  4x +y

balance

The intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...

  x +3y = 4x +y

_____

Additional comment

This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:

  x +2y = 4x . . . . subtract y from both sides

  2y = 3x . . . . . . . subtract x from both sides

  y = (3/2)x . . . . . divide by the coefficient of y

This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

B: if x is 6, what is y?

Answers

Answer:

Step-by-step explanation:

4x + y = x + 3y

if x = 6 then

3*6 = 2y

18 = 2y

y = 9

Y=9

A map of a town has no scale. You know that the distance between the post office and the park is 2 mi. On the map it is 2 in. Also, on the map you know the distance from the park to the school is 8 in. What is the actual distance in miles between the park and the school?
A. 0.5 mi.
B. 4 mi.
C. 8 mi.
D. 16 mi.

Answers

The answer is C

If you are given a 2 inch distance from the post office to the park and it’s known that 2 inches= 2 miles and you also know that the distance from the park to the school is 8 inches which is 4 times more than the distance from the post office to the park then you know that the amount of miles will be 4 times more than 2 miles so, 4x2=8 which means that the distance between the park and school is 8 miles.

Hope that makes sense :))
It’s eight miles, as you can see 2 miles = 2 inches which means every inch is one mile, so eight inches means eight miles! Hope this helps.
