Step-by-step explanation:

4z - 4.4 = 3.6  also means 4z = 3.6 + 4.4  which is 4z = 8

4 times 2 = 8

For proof do 4 times 2 minus 4.4 = 3.6

Answer:

The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.

Answer:

40.9

Step-by-step explanation:

8 is beside 5 which is a large number so you add 1 to 8

Answer:

40.9

Step-by-step explanation:

if you rounded to 2 decimal places the answer would be:

40.83.

because the second number after the decimal is 5 or more, we have to round upwards.

this brings us to 40.9 which has 1 decimal place.

The expression for the amount of money to buy 'b' books is

(A.) 7.50 times b

if the camp leader has 12 campers the amount of money will be$90.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A camp leader buys a book for each of her campers. She spends $7.50 on each book.

Assuming he bought 'b' no. of books.

∴ The expression for the amount of money to buy 'b' books is 7.50b.

Now if the camp leader has 12 campers the amount of money will be (7.5×12) = $90.

Answer:

6.5 inches

Step-by-step explanation:

Suppose we get 24 inches of snow tomorrow

The next day becomes warm.

The weather remains warm for the next several days.

The snow melts at 2.5 inches a day

Therefore the amount of snow that will be left after 7 days can be calculated as follows

= 2.5 ×7

= 17.5

Since the initial amount of snow was 24 inches then,

24 -17.5

= 6.5

Hence the amount of snow that will be left on the ground after 7 days is 6.5 inches

Answer:

  1.6 cups

Step-by-step explanation:

2 servings is 1/5 of 10 servings, so the amount of water needed is 1/5 of 8 cups.

  (1/5)(8 cups) = 8/5 cups = 1.6 cups

1.6 cups of water are needed for 2 servings.

Answer:x = 7.667

Step-by-step explanation:

3x - 8 = 15

     + 8 = 23

3x = 23

divide 3 by 3 and 23 so you get x by itself

answer = 7.667

Answer:

x = 7.667

Step-by-step explanation:

3x - 8 = 15 (Rearrange expression)

-8 - 15 = -3x (Combine like terms)

-23 = -3x (Divide)

x = 7.667

Answer:

(–2.2, –1.2)

Step-by-step explanation:

o divide the segment into a 3:2 ratio, we need to divide the segment into five identical parts, and find the point that divides the segment into 3/5 and 2/5. To do this we have to calculate the distance between the two points of the segment, in x and y, we can do this by just subtracting the two "y" coordinates and the two "x" coordinates:

Δy=║-4-3║=7

Δx=║-1-(-4)║=3

Then we divide those differences by 5.

7/5=1.4

3/5=0.6

and now, we multiply those results by 3 and subtract them or add them from the coordinates of the point G (subtract them from the coordinate y and add it to the coordinate x, because we are moving down and right).

Px=-4+3*0.6=-2.2

Py=3-3*1.4=-1.2

so the coordinates of the point we are looking for (which I called "P") are:

P(-2.2, -1.2).

That completely depends on what ' x ' is.

Answer:

adult tickets 15

child tickets  12

Step-by-step explanation:

2x + 2y = 54   L1

3x + 5y = 105  L2

3L1 - 2L2

6x + 6y = 162

-6x - 10y = -210

-4y = -48

y = -48/-4

y = 12

2x + 2y = 54

2x +2(12) = 54

2x + 24 = 54

2x = 54 - 24

2x = 30

x = 15

Answer:

The car is travelling faster.

Step-by-step explanation:

Given that,

Distance between two cities = 243 miles

Time of train = 4 hours

Speed of car = 65 miles/hours

We need to calculate the speed of train

Using formula of speed

[tex]v=\dfrac{d}{t}[/tex]

Where, d = distance

t = time

Put the value into the formula

[tex]v=\dfrac{243}{4}[/tex]

[tex]v=60.75\ miles/ hours[/tex]

Hence, The car is travelling faster.

the reciprocal will be negative

Answer:

The reciprocal of a negative number must itself be a negative number so that the number and its reciprocal multiply to 1.

The reciprocal of a positive or negative fraction is obtained by switching its numerator and denominator, the sign of the new fraction remains the same. ... Notice that when you multiply negative fractions with their reciprocals, the product is always 1 (NOT -1).

Answer: 18 milles

Step-by-step explanation: ince we have to figure out how many miles away Mr. Hill lives, first we will subtract:

30 - 3 = 27

Then, divide

27 ÷ 1.50 = 18

So, Mr. Hill lives 18 miles away

Answer:

18miles

Step-by-step explanation:

Full cost minus the original cost.

30-3=27

Now you have to divide the cost by 1.5 because you have to find the distance and that is the cost per mile.

$27/1.5=18mi

Answer:

2.4

Step-by-step explanation:

To find the mean absolute deviation, find how much each value is away from the mean, and divide it by the number of numbers you have. In this case, the mean is 5, and the deviation of each number is 4, 2, 0, 2, and 4. Add these up and you get 12. Divide 12 by the number of numbers which you have, which is 5, to get 2.4.

We have that The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is

[tex]\sigma=2.24[/tex]

From the question we are told

Find the mean absolute deviation of the set of data. 2, 3, 5, 7, 9

Generally the equation for the mean absolute deviation  is mathematically given as

[tex]\sigma={\frac{\sum(x-u)}{N}[/tex]

Where

[tex]x=\frac{2+3+5+7+9}{5}\\\\x=5.2[/tex]

Therefore

[tex]\sigma={\frac{\sum(x-u)}{N}\\\\\sigma=\frac{3.2+2.2+0.2+1.8+3.8}{5}\\\\\sigma=2.24[/tex]

Therefore

The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is

[tex]\sigma=2.24[/tex]
