Answer:

X=60+6×2

Step-by-step explanation:

Sorry im not great at math but i think that this would be the answer because Murphy is 6 years younger than Emma. It then says TWICE so i assume it means multiply by two. 6×2= 12 so Emma is 12 years older.

Answer:

10 cm

Step-by-step explanation:

because RT = 35 and RS = 75 so ST = 70

The length of SQ is 10 cm.

Option A is the correct answer.

We have,

Two similar triangles.

ΔTPQ and ΔTRS

So,

TR/TP = TS/TQ

TR = (TP +PR)

TS = (TQ + QS)

Substituting.

TR/TP = TS/TQ

(TP + PR)/TP = (TQ + QS)/TQ

(30 + 5) / 30 = (60 + QS) / 60

35/30 = (60 + QS) / 60

7/6 = (60 + QS) / 60

7 = (60 + QS) / 10

70 = 60 + QS

QS = 70 - 60

QS = 10

Thus,

The length of SQ is 10.

Answer:

Fraction: y= 3/2x-3

or

Decimal: y= 1.5x-3

Step-by-step explanation:

Turn 3x-2y=4 into y=mx+b form

Subtract 3x from both sides

-2y=4-3x

Divide -2 from both sides

y= -2+3/2x

y= 3/2x-2

Since the line is parallel, use slope 3/2

Answer:

170

Step-by-step explanation:

Ann, Ben, and Cindy were eating strawberries.

The ratio of the numbers of berries they ate is 5:5:7.

If Cindy ate 30 strawberries less than Ann and Ben together,

find:

what is the total number of strawberries the three of them ate?

solution:

add the ratios 5 + 5 + 7 = 17

since Cindy ate 30, less than Ann and Ben together so, the equation is

7x = 5x + 5x - 30

7x - 10x = -30

x = 30/3

x = 10

ann 5 x 10 = 50

ben 5 x 10 = 50

cindy 7 x 10 = 70  

total            = 170

a = lilies

13 - a = tulips

We have: 1.25a + 0.90(13 - a) = 14.85

              => 1.25a + 11.7 -0.90a = 14.85

              => 0.35a                      = 14.85 - 11.7 = 3.15

              => a                              = 3.15 ÷ 0.35 = 9

=> She bought 9 lilies and 4 tulips

Using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

The law of Syllogism is a method of deductive reasoning which involves drawing a conclusion from two premises.

Applying this law, there are usually three statements.

Statement 1: If a, then b (premise)

Statement 2: If b then c (premise)

Statement 3: If a, the c (conclusion)

In the question above, in the same vein, from the first and second statement, we can conclude that:

If a figure is a square, then it is not a triangle, because a square has 4 sides and a triangle doesn't.

Therefore, using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

Answer:

(in order):  4, 8, -2, -2

Step-by-step explanation:

The slope of MN = -1.

The slope of M.N. = -1.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given information:

The two lines MN and M'N' are parallel.

Transformation rule:

Line MN was translated down to 4 units and right to 6 units to create line M'N'.

And line MN passes through two points (-2, 0) and (-6, 8).

Therefore, the slope of line MN,

= (8- 0)/(-6-2)

= -1

Since lines MN and M'N' are parallel, they have the same slope.

Therefore, the slope of M'N' is also -1.

Answer:

.36666667

Step-by-step explanation:

Answer:

y = x - 5 :)

Step-by-step explanation:

use point-slope form to create an equation for this line.

find the slope first by subtracting the y-values from each other, and the x-values from each other.

-3-(-8) = 5                       <- y-value

2-(-3) = 5                        <- x-value

5/5 = 1                            <- slope

plug the slope and one of the points into the point-slope equation.

y - (-3) = 1(x - 2)

y + 3 = x - 2

subtract 3 from both sides.

y = x - 5

graph this by placing a point on -5 on the y-axis, and going up by 1 and right by 1 for the slope of 1.

hope this helped! xoxxo

Step-by-step explanation:

Hey there!

The line passes through points; (-3,-8) and (2,-3).

Now; use formula for double point.

[tex](y - y1) = \frac{y2 - y2}{x2 - x1} (x - x1)[/tex]

Put all values.

[tex](y + 8) = \frac{ - 3 + 8}{2 + 3} (x + 3)[/tex]

Simplify it.

[tex](y + 8) = \frac{5}{5} (x + 3)[/tex]

[tex]y = x + 3 - 8[/tex]

[tex]y = x - 5[/tex]

Therefore, the equation is y= x-5.

Answer:

x = -1

Step-by-step explanation:

5 less than a number is equivalent to 1 more than three times the number

number = x

x - 5 = 3x + 1

now im going to get the numbers and variable on different sides

x - 5 + 5 = x

3x + 1 - 3x = 1

x + 3x = 4x

1 - 5 = -4

4x = -4

lastly im going to divide each side by 4

4x / 4 = x

-4 / 4 = -1

x = -1

Step-by-step explanation:

First, distribute. 12r + 16 = -16r - 40

Then get r on one side by adding 16r to both sides then subtracting 16 from both sides.                  28r = -56

Finally, divide by 28 on both sides to get r by itself.

r = -2

Answer: 8 chess matches and 11 cribbage matches.

Step-by-step explanation:

60 people, 4 people play a match of cribbage, so if theres 3 more  matched than chess we can subtract that from the total 60 to get the answer. 3x4=12 60-12=48, 2 people per chess game and 4 people per cribbage game add them 6, 48 divided by 6 since its an even amount now, 48/6=8 add 8 matched to the remaining 3 for the cribbage.

8 chess games are being played while 11 cribbage games are being played.

Let x represent the number of chess games and y represent the number of cribbage games.

Since there are 60 people, chess is a two-player game and cribbage is a four-player game, hence:

2x + 4y = 60  (1)

There are 3 more games of cribbage than games of chess, hence:

y = x + 3

-x + y = 3    (2)

Solving equations 1 and 2 simultaneously gives:

x = 8, y = 11

Therefore 8 chess games are being played while 11 cribbage games are being played.
