Answer: Below

Step-by-step explanation:

Looking at the numbers, they already seem to be multiples of fours. If we try to scale four up, 12 is the next biggest factor.
84 = 12 * 7
48 = 12 * 4
7 + 4 = 13
12 * 13 = 84 * 48
12 * 13 = 132

Answer:

x = -1, y = 1

Step-by-step explanation:

Multiply the top equation by 2:

[tex]2x - 2y = - 4[/tex]

Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:

[tex]9x = - 9[/tex]

Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.

[tex]x = - 1[/tex]

[tex]7( - 1) + 2y = - 5[/tex]

[tex] - 7 + 2y = - 5[/tex]

[tex]2y = 2[/tex]

[tex]y = 1[/tex]

Answer:

Step-by-step explanation:

using the sine ratio in the right triangle.

sin23° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{7}[/tex] ( multiply both sides by 7 )

7 × sin23° = x , then

x ≈ 2.7 ( to the nearest tenth )

----------------------------------------------------

using the tangent ratio in the right triangle

tan x = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{27}{17}[/tex] , then

x = [tex]tan^{-1}[/tex] ( [tex]\frac{27}{17}[/tex] ) ≈ 57.8° ( to the nearest tenth )

Answer:

a) 3x

b) 3x

c) 2 2/3 times greater

Step-by-step explanation:

The length of the rectangle:

The width of the rectangle is x. If you add the two widths together when finding perimeter, x + x, that would give you 2x.

Sum of widths: x + x = 2x

Use the sum of the widths to find the sum of the lengths by subtracting from the perimeter.

sum of lengths = perimeter - sum of widths

8x - 2x = 6x

Since there are 2 lengths divide by 2.

6x/2 = 3x

The length of the rectangle is 3x

Perimeter of the square:

The sides of the square are 1/4 of the length of the rectangle. "of" means to mulitply: (I made 3x a fraction by placing it over 1)

[tex]\frac{1}{4} (\frac{3x}{1} )[/tex] = [tex]\frac{3}{4} x[/tex]

Now find the perimeter of the square by multiplying the side length by 4.

[tex]\frac{3}{4}x(\frac{4}{1} )[/tex] = [tex]3x[/tex]

Last part:

solve the rectangle's perimeter by substituting x with 4.

P = 8x

P = 8(4)

P = 32 cm

Solve the square's perimeter by substituting x with 4.

P = 3x

P = 3(4)

P = 12 cm

Divide the rectangle's perimeter by the square's perimeter.

32/12 = 2 2/3 times bigger.

Based on the outcomes, the estimated probability of the spinner landing on blue which has equal sections colored blue, yellow, and red is 0.22 or 22%.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

This table shows outcomes of a spinner with 3 equal sections colored blue, yellow, and red.

The total number of outcome is 100. The total number of favorable outcome to land blue is 22.

Thus, the estimated probability of the spinner landing on blue has to be found out is,

[tex]P=\dfrac{22}{100}\\P=0.22\\P=22\%[/tex]

Hence, based on the outcomes, the estimated probability of the spinner landing on blue which has equal sections colored blue, yellow, and red is 0.22 or 22%.

Answer:

x=2
y=5

Step-by-step explanation:

Since we have an equation that is set equal to why with x in it, we can multiply it by 2 to get 6x-2=2y.

We can then plug that in for 2 +2y in the equation above, giving us 3x+6x-2=16 or 9x-2=16.

From there we add 2 to both sides and get 9x=18.

Then divide both sides by 9 to get x=2.

Then plug x=2 in for the equation below and get 6-1, or 5.

Giving us our answers, x=2 and y=5

Answer:

slope of a line parallel to this line= -3/8

slope of a line perpendicular to this line= 8/3

Step-by-step explanation:

The general equation of a line in terms of a and b is:

y=ax+b  where a=slope

in order to get the slope of the line we have to write its equation as the form shown above:

3x+8y=1

8y= -3x+1

y= (-3/8)x+(1/8)

so slope= -3/8

Parallel lines have equal slopes

⇒ slope of parallel line= -3/8

The slope of the line perpendicular to another line is the opposite reciprocal of the original line's slope. This means that we have to exchange the numerater by the denomenator and multiply the obtained number by a negative sign:

⇒ slope of perpendicular line= -(-8/3) = 8/3

Answer:

0,24 m

Step-by-step explanation:

La table est un rectanble donc l'angle en  haut à droite est de 90°.

Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.

On sait que tan(â) = [tex]\frac{Cote oppose}{Cote adjacent}[/tex] donc :

tan(40)= [tex]\frac{1,27}{x}[/tex]

[tex]\frac{1,27}{tan(40)} = x[/tex]

donc x ≈ 1,51 m

Le trou du mileu est à [tex]\frac{2,54}{2}[/tex] soit 1,27m du bord.

Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.

Answer:

y = 120°

Step-by-step explanation:

If AC ≅ AD and BC ≅ BD then the shape of the figure is a kite.

Therefore, ∠D ≅ ∠C

Sum of interior angles in a kite = 360°

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ 120° + ∠B + 100° + 100° = 360°

⇒ ∠B = 40°

Sum of interior angles of a triangle = 180°

⇒ ∠B + ∠BDY + ∠y = 180°

⇒ 40° + 20° + ∠y = 180°

⇒ ∠y = 120°

Step-by-step explanation:

slope of MN (y2-y1)/(x2-x1) = (2-3)/(-3-2)= -1/-5 = 1/5

line MN and line K is perpendicular

(1/5)*(m2) = -1  

slope of k which is m2 is -5

slope of K (y2-y1)/(x2-x1)= 5

slope of MN (-3-y1)/(3-x1)=5

Step-by-step explanation:

Answer:

y = - 2x

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 2 . then

y = - 2x + c ← is the partial equation

to find c substitute (2, - 4 ) into the partial equation

- 4 = - 4 + c (add 4 to both sides )

0 = c

y = - 2x + 0 , that is

y = - 2x ← equation of line

Answer: Attached photos, and the last question of my explanation.

Step-by-step explanation: If "bracelets cost $3 and necklaces cost $6"  that means we will multiply.

1. for Bracelets (1 bracelet = $3)

(0 x 3 = 0) 1. $0

(1 x 3 = 3) 2. $3

(2 x 3= 6) 3. $6

(3 x 3 = 9) 4. $9

(3 x 4 = 12) 5. $12

Explanation: We have to multiply 5 different numbers to fill in the 5 rows of bracelets & necklaces. (0,1,2,3,4 = 5 numbers). For example, if we buy 2 bracelets, 1 bracelet = $3 and 3*2=6 so it would be 6.

2. for Necklaces (1 necklace equals $6)

(0 x 6 = 0) 1. $0

(1 x 6 = 6) 2. $6

(6 x 2 = 12) 3. $12

(6 x 3 = 18) 4.  $18

(6 x 4 = 24) 5. $24

3. coordinates

1. (0,0)

2. (3,6)

3. (6,12)
