I  just did this question

Answer: 3/4

Step-by-step explanation:

The mother can make 3 green curtains and 5 white curtains, using the greatest common divisor of 75 and 125 yards which is 25. Each curtain would thus be 25 yards.

This question can be solved using the concept of Greatest Common Divisor (GCD), which finds the largest possible length that can divide two given lengths without leaving any remainder. In this case, the lengths are 75 yards and 125 yards, which are the quantities of green and white fabric respectively. The GCD of 75 and 125 is 25.

Therefore, the largest number of curtains that can be made is based on this length, which means the mother can make 75/25=3 green curtains and 125/25=5 white curtains. Each curtain would be 25 yards.

Answer:

is it 2/21 i hope im right cuz i just looked it up

Step-by-step explanation:

To find the sum, convert the fractions to have the same denominator. Add the whole numbers and the fractions separately. The sum of 12 1/4 and 5 5/6 reduced to lowest terms is 17 13/12.

To find the sum of 12 1/4 and 5 5/6, we need to convert the fractions to have the same denominator. The common denominator for 4 and 6 is 12. So, we can rewrite 12 1/4 as 12 3/12 and 5 5/6 as 5 10/12. Now we can add the whole numbers, 12 and 5, which gives us 17. Then, we add the fractions, 3/12 and 10/12, which equals 13/12. Therefore, the sum of 12 1/4 and 5 5/6 reduced to lowest terms is 17 13/12.

Answer:

X = -5

Step-by-step explanation:

3X=-15

Lets solve the equation for x.  We will isolate x by dividing each side by 3

3X/3 = -15/3

X = -5

Method 1:

Solve the equation

3x = -15     divide both sides by 3

3x : 3 = -15 : 3

x = -5

Method 2:

Put the value of x to the equation:

L = 3(-5) = -15

R = -15

L = R    CORRECT

Answer:

Since both sides equal, there are infinitely many solutions

Step-by-step explanation:

Simplify brackets

2/3×3/1=1

Use this rule: a/b×c/d=ac/bd

Simplify 2×3 to 6

6/3×2=1

Simplify 3×2 to 6

cancel 6

1=1

Since both sides equal, there are infinitely many solutions

I can't exactly SHOW you where to put the numbers, but I can teach you the process of how you'd do it.

First off, label your number line from 0-15, as it is the simplest. (You'd be counting by 1 per each line). Then, follow this process:

1) Look at the first digit of your value. Place your number according to your first digit. (So, you'd put 0.365 at the 0 line and 3.521 at the 3 line)

2) Look at the second digit of your value. Imagine that between the two main lines (0-1 and 3-4) that there is 10 smaller lines. Then, you can place your number according to your second digit. (So, you'd put 0.365 at the 0.3 line and 3.521 at the 3.5 line).

3) Look at the third digit of your value. Imagine that between the two smaller lines (0.3-0.4 and 3.5-3.6) that there is 10 smaller lines. Then, you can place your number according to your third digit. (So, you'd put 0.365 at the 0.36 line and 3.521 at the 3.52 line).

4) Look at the fourth digit of your value. Imagine that between the two even smaller lines (0.36-0.37 and 3.52-3.53) that there is 10 smaller lines. Then, you can place your number according to your fourth digit. (So you'd place 0.365 at the 0.365 line and 3.521 at the 3.521 line)

Answer:

x=18

Step-by-step explanation:

We need to find the areas of the rectangles

1st rectangle

A= l*w

A = (2x+4)*9

   = 18x+36

2nd rectangle

A = l*w

   = 15*(3x-30)

    = 45x-450

Since the area of the rectangles are equal, we set these two equations equal

18x+36 = 45x-450

Subtract 18x from each side

18x-18x+36 = 45x-18x-450

36 = 27x-450

Add 450 to each side

36+450 =27x

486 = 27x

Divide by 27 on each side

486/27 = 27x/27

Answer:

Measures of all angles is either 77.5° or 102.5°

Step-by-step explanation:

See the attached figure.

As shown:

line a parallel to line b with transversal m

So, all the angles are either congruent or supplementary.

Let the supplementary angles x and y and y > x

x + y = 180° ⇒ (1)

one angle is 25° bigger than another

y - x = 25° ⇒ (2)

solving (1) and (2)

∴ x = 77.5°  and y = 102.5°

Answer,

(26/2) * 3

= 39

Explanation,

26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.

Hope this helps :-)

Substitution method

y = x + 3   (*)

y = 3x + 1  (**)

Substitute (*) to (**):

3x + 1 = x + 3      subtract 1 from both sides

3x = x + 2       subtract x from both sides

2x = 2        divide both sides by 2

Put the value of x to (*):

y = 1 + 3

Answer:

A'(3, - 1)

Step-by-step explanation:

Under a reflection in the y-axis

a point (x, y) → (- x, y), hence

A (- 3, - 1) → A'(3, - 1)

The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates.

Given here: The coordinate of a Triangle A as (-3,-1)

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Thus The vertex of the triangle (-3,-1) it changes to (3,-1)

The algebraic representation for the transformation is given by '

(x,y)⇒(-1×x,1×y)

     ⇒(-x, y)

Hence, The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

I honestly don't know or I would have replied. Sorry :(

Answer:  y = -2

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

Explanation:

Find the slope of line m using the slope formula

slopeM = (y2-y1)/(x2-x1)

slopeM = (2-8)/(-1-6)

slopeM = -6/(-7)

slopeM = 6/7

The slope of line m is 6/7. The perpendicular slope is -7/6. We flip the fraction (aka reciprocal) and flip the sign (from positive to negative). The phrase "flip the fraction and flip the sign" is a handy way to think of "negative reciprocal", at least in my opinion. Note how the two slopes 6/7 and -7/6 multiply to -1 to prove they are perpendicular slopes

We'll use the slope formula again to set up the slope for line n. We don't know y, but we can set the fraction equal to -7/6 and solve for it.

slopeN = (y2-y1)/(x2-x1)

slopeN = (y-5)/(5-(-1))

slopeN = (y-5)/(6)

-7/6 = (y-5)/6

-7*6 = 6(y-5)

-42 = 6y-30

6y-30 = -42

6y = -42+30

6y = -12

y = -2

So in short, if y = -2, then line n goes through (-1,5) and (5,y) = (5,-2). The slope of line N is computed to be...

slopeN = (y2-y1)/(x2-x1)

slopeN = (-2-5)/(5-(-1))

slopeN = (-2-5)/(5+1)

slopeN = -7/6

which is the proper slope value we want.

Answer:

£ 75.60

Step-by-step explanation:

4 m ↔ £ 33.60

1 m ↔ £ 8.40

9 m ↔ £ 75.60

The cost of one meter of timber is £8.40, calculated by dividing £33.60 by 4. To find the cost of 9 meters, multiply £8.40 by 9, resulting in a total cost of £75.60.

To determine the cost of 9 meters of timber when we know that 4 meters cost £33.60, we can use a unit rate approach. First, we need to calculate the cost of one meter of timber by dividing the total cost by the number of meters. Then, we multiply the cost per meter by 9 to find the cost of 9 meters of timber.

Therefore, the cost of 9 meters of timber would be £75.60.
