Answer: 7 1/2 pounds

Step-by-step explanation:

Answer:

Luke = 12 games

Naliba = 6 games

Step-by-step explanation:

Luke and naliba are playing squash

Luke wins twice as many games as naliba

They play a total of 18 games

Luke= 2x

naliba = x

2x +x= 18

3x= 18

x= 18/3

x= 6

Luke= 2(6)

= 12

naliba= 6

Hence luke wins 12 games and naliba wins 6 games

Answer:

x=130 I believe

Step-by-step explanation:

28+8+14+x=180

50+x=180

x=130

Answer:

29 students

Step-by-step explanation:

divide by 7 to get 1/9 then multiply by 9 to get total.

Answer:

27

Step-by-step explanation:

Let x be the total number of students. So, turning the words of the problem into an equation, we get:

7/9x = 21,

then, 7x = 189

so, x = 27.

Answer:

78.54

Step-by-step explanation:

Area of a circle = pi time radius power of 2

A = pi*r^2

A = 3.14 * 5^2

A = 3.14 * 25

A = 78.54

22 percent is the loss ....

Answer: = cos 4x

[tex]\frac{tan2x}{tan4x-tan2x}\\\\=\frac{tan2x}{\frac{2tan2x}{1-tan^{2}2x }-tan2x }\\\\=\frac{tan2x(1-tan^{2}2x) }{2tan2x-tan2x(1-tan^{2}2x) }\\\\=\frac{tan2x(1-tan^{2}2x) }{tan2x(2-1+tan^{2}2x) }\\\\=\frac{1-tan^{2}2x }{1+tan^{2}2x } \\\\=\frac{1-\frac{sin^{2}2x }{cos^{2}2x } }{1+\frac{sin^{2}2x }{cos^{2}2x } }\\\\=\frac{cos^{2}2x-sin^{2}2x }{cos^{2}2x+sin^{2}2x } \\\\=\frac{cos4x}{1}\\\\=cos4x[/tex]

Step-by-step explanation:

You find the intersection point of the two lines, which is (3, -2).

It is what the question meant when it asked for "solution".

These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with

x+y=20

x-y=10

Hope this clears up your confusion.

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Since ΔMNO maps to ΔRST with a transformation (x, y) = (3x, 3y), this means that ΔRST is three times the size of ΔMNO, hence all the sides of ΔRST are three times that of ΔMNO.

A. If RT = 3, MO = 9. A True B False B.

This is false because RT = 3 * MO = 3(9) = 27

B. If RT = 12, MO = 4. A True B False

This is true because RT = 3 * MO = 3(4) = 12

C. If RT = 9, MO = 27. A True B False

This is false because RT = 3 * MO = 3(27) = 81

Answer:

HA , LJ , and IK contain the center of dilation. Line segments that contain the center of dilation in the preimage also contain the center of dilation in the image. GF , HI , and KL do not contain the center of dilation. Line segments that do not contain the center of dilation in the pre image are mapped onto distinct lines parallel to the original, corresponding line segment. HL does not contain the center of dilation either but it does lie on a line that passes through the center of dilation. Line segments that lie on lines passing through the center of dilation in the preimage lie on the same lines in the image.

Answer:

-1

Step-by-step explanation:

-5x – 15 > 10 + 20x

-5x -20x > 10+15

-25x > 25

x < -1

Answer:

to this question is it is 1.01

Answer: -46

Step-by-step explanation:

Consecutive means next in order.

Sum means answer to an addition problem.

-45 + -46 = -91

-46 is smaller (farther away from zero) than -45

Answer:

You have to fine the number that matches with the "X" so the answer would be 126 divided by 43 which is 2.9. 2.9 is closer to 3 than 2 so the "x" is 3
