XD is an emoticon commonly used to symbolize dying from laughter. It represents 2 closed eyes with the X and mouth with the D.

The solution of the equations is (-2, -1)

2x - 3y = -1

11x  - 9y = -13

Using elimination method let multiply the first equation by -3.

Therefore,

-6x + 9y = 3

11x - 9y = -13

5x = -10

x = -10 / 5

x = -2

let's find y as follows;

2(-2) - 3y = -1

-4 - 3y = -1

-3y = -1 + 4

-3y = 3

y = 3 / -3

y = -1

Answer:

The coordinates of the midpoints are the average coordinates of the endpoints. Suppose (x1,y1) and (x2,y2) are the endpoints and (xm,ym) is the midpoint, we have xm=x1+x22 and ym=y1+y22 . Therefore, 2xm=x1+x2 and 2ym=y1+y2 . From there, we should be able to figure the other endpoint out given an endpoint and the midpoint.

Answer:

6-2x=10

Step-by-step explanation:

6-2x=10 is the answer.

Six less than means 6-

Twice a number means 2 and the unknown value "x" or it can also be "y"(it can be any letter since it is an unknown value) but we usually use "x" in this case.

When we are given "twice a number" in a sentence it means that that number is unknown.

Less than twice a number means -2x

Less than thrice a number means -3x

So,

six less (6-)

than twice a number (2x)

is 10 (=10)

Answer:

1/48 cups of sugar in one muffin

Step-by-step explanation:

We're essentially looking for the unit rate.  

Thus, we can simply do (1/2) / 24, which is 1/48.

The quantity of sugar in each muffin is 0.021 cup.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Steven used 1/2 cups of sugar to make 24 muffins.

Quantity of sugar in each muffin = Quantity of sugar/Number of muffins

= 1/2 ÷24/1

= 1/2 ×1/24

= 1/48

= 0.021 cup

Therefore, the quantity of sugar in each muffin is 0.021 cup.

Step-by-step explanation:

See attached workings

a)  You should be able to see that this is a series of 3^n.

3 = 3^1   9 = 3^2   27 = 3^3  etc.

b)  This is a series of 1/n:

Answer:

0.81.

Step-by-step explanation:

1) the required probability Hot_from_Large can be calculated as:

[tex]P(Hot \ | \ Large)=\frac{LargeHot}{LargeHot+LargeCold};[/tex]

2) according to the ratio above:

[tex]P(Hot \ | \ Large)=\frac{22}{22+5} =0.(814)=0.81.[/tex]

The probability that a customer ordered hot drink given that he or she ordered a large 29.3%.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Here,

P(Large| Hot) = n(Large and Hot)/n(Hot)

Using the data on the given table, we have:

P(Large| Hot) = 22/(5 + 48 +22)

P(Large| Hot)  = 22/75

= 0.2933

= 29.3%

Hence, the probability that a customer ordered hot drink given that he or she ordered a large 29.3%.

Answer:

1/6 is the distance left to cover

Step-by-step explanation:

A kilometer is equal to 1 whole. In this scenario, you jog 1/6, and 2/3. Since 6 is a multiple of 3, we can use the common denominator to convert 2/3 into 4/6. Then we can our two distances, 4/6 and 1/6, to get a total of 5/6.

Then subtract from the whole.

Step-by-step explanation:

From the income provided, the taxable income will be $42170.

From the complete information, the calculation goes thus

First $9525 = 10% = $952.50

Next $9525 - $38700 = 12% = $3501.00

Next $38700 - $82500 = 22% = $9636

Next $82500 - $157500 = 24% = $18000

Next $157500 - $189000 = $10080

Taxable Income = $952.50 + $3501.00 + $9636 + $18000 + $10080

= $42170

Answer:

1 3/5 boxes

Step-by-step explanation:

There are 5 1/2-3 9/10 boxes left over. We need to simplify this expression.

First, convert both fractions to improper fractions:

11/2-39/10

Now, convert both fractions to have a common denominator of 10:

11/2*5/5 (note we can only do this because any number over itself is equivalent to 1, so technically this is multiplying the number by 1)

55/10-39/10=16/10

Convert it back into a mixed fraction:

1 6/10=1 3/5 boxes

Answer:

1 3/5 boxes

Step-by-step explanation:

5 1/2=5 5/10

leftover=5 5/10-3 9/10=1 6/10=1 3/5

Answer:

  A. 12.5 ft

  B. not in proportion (should be 2.5 ft, not 2.25 ft)

Step-by-step explanation:

A scale model is one in which all linear dimensions of the model have the same ratio to corresponding linear dimensions of the object being modeled.

Here, that relationship means ...

  actual length/model length = actual height/model height

  actual length/(1.25 ft) = (10 ft)/(1 ft)

  actual length = (1.25 ft)(10/1) = 12.5 ft

__

If the actual wheel has the same scale, we will have ...

  actual diameter/(6 inches) = (10 ft)/(1 ft)

  actual diameter = (6 inches)(10/1) = 60 inches = 5 ft

  actual radius = (5 ft)/2 = 2.5 ft . . . . . at the same model scale

Since the actual wheel radius is 2.25 feet, it is not in proportion to the rest of the model.

20 bottles for 28

Step-by-step explanation:

15 ÷  10 = 1.5

28 ÷ 20 = 1.4

Step-by-step explanation:

let the unknown members be X

At first, the club had 20 + X members

After the first year,

2( 20+X)

The second year,

2( 20 +X/2) +40

The third year,

3[2(20+ X/2) +40]

Total number =

20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]

= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]

= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
