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.

__

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

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

  4x +y

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.

Answer:

4 textbooks

Step-by-step explanation:

3 kg = 3000 g

3000 ÷ 650 = 4.61......

Maximum number is 4 as 0.61... book being carried is not possible

Hope this helped and brainliest please

The maximum number of these textbooks that the rucksack can hold are,

⇒ 4 textbooks

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A rucksack can hold a maximum of 3 kg.

A particular textbook has a mass of 650 g.

Hence, We get;

⇒ 3 kg = 3000 g

Thus, the maximum number of these textbooks that the rucksack can hold is,

⇒ 3000 ÷ 650

⇒ 4.61

Thus, the maximum number of these textbooks that the rucksack can hold is, 4

Answer:

406

Step-by-step explanation:

A rectangular prism has six sides, three pairs of matching ones

Start by finding the area of each of the three kinds of sides

14 x 5 = 70

5 x 7 = 35

7 x 14 = 98

Now multiply each of these answers by two, for the number of sides that have each surface area

140

70

196

Finally, add all of the areas together to find the surface area of the whole shape.

140 + 70 + 196 = 406

Answer is both covered same level of brightness

sorry for bad handwriting

Both candles covered the same space by the light per candle.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Nayeli light a 4m² space with 12 candles. The space covered by the light per candle is calculated as,

⇒ 4/12

⇒ 0.3333 m² per candle

Citlali lights a 10m² space with 30 of the same type of candles. The space covered by the light per candle is calculated as,

⇒ 10/30

⇒ 0.3333 m² per candle

Answer:

A : 256

B : 8

I am like super unsure ngl

Step-by-step explanation:

(REMOVE THIS, my friend by accident posted this.)

Reason:

x = number of textbooks

650x = weight of all x books, at 650 grams each

3 kg = 3000 g

650x = 3000

x = 3000/650

x = 4.615 approximately

Round down to the nearest integer. This is because 4 textbooks weigh 4*650 = 2600 grams = 2.6 kg; while 5 textbooks weigh 5*650 = 3250 grams = 3.25 kg which is over the weight limit.

This means 4 books is the most the rucksack can hold. This is of course only when we have 4 of the same exact book.

Answer:

702

Step-by-step explanation:

The best way to do it is to divide 13 into 702. 13 doesn't go into 7 but it does go into 70 5 times. 70 - 65 = 5. Once you bring down the 2, 5 turns into 52 which 13 goes evenly into it 4 times. So your answer for that is 54. Then to get your number you multiply 54 with 13 and you get 702. So 702 is your answer.

Answer:

Draw an open circle at 11.

Shade all numbers to the right of 11.

Step-by-step explanation:

If you have an inequality that has a < or a > symbol, then your circle is open.

Because x is greater than 11, you would shade the numbers greater than 11, or to the right of 11.

Answer:

Draw an open circle at 11.

Shade all numbers to the right of 11.

Step-by-step explanation:

she draws an open circle because the "greater than" sign is not "greater than or equal" if it is the sign "greater than or equal" the circle should be a closed circle.

And she shades all numbers to the right of 11 because "x" is greater than 11 and she shades the side that is positive, not negative.

Answer:

B

Step-by-step explanation:

An exponent is a number multiplied by itself several times. 5x5x5 is multiplying 5 three times, so it would be 5 to the power of 3.

Hey there!

5 * 5 * 5

= 5^3

= 25 * 5

= 25 + 25 + 25 + 25 + 25

= 50 + 50 + 25

= 100 + 25

= 125

Thus, the equation answer should be:

125

Therefore, the overall answer should be: 5^3

(Because you’re EXPRESSING 5 THREE times)

A transversal is a line that intersects a system of lines. The transversal in this case, would be line a.

Step-by-step explanation:

Answer:

1/6 for each side.

Step-by-step explanation:

The equation of line parallel to y = -2/3x + 3 and passing through (7, 3) will be y = -2/3 x + 23 / 3. Then the correct option is C.

When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.

The equation of a line is given below.

y = -2/3 x + 3

Then the slope of the line will be

m = -2/3

Then the equation line which is having a slope of - 2/3 will be

y =  -2/3 x + c

The line is passing through (7, 3). Then we have

3 = -(2/3) (7) + c

3 = -14/3 + c

c = 3 + 14/3

c = 23/3

Then the equation will be

y = -2/3 x + 23 / 3

Then the correct option is C.
