Actually Welcome to the Concept of the linear equation in two variables.

So we have to form two equations to solve this.

Let the number of children be 'x' and number of adults be 'y'.

hence, we get as,

x+y = 630 ..... (1)

and also, to their total cost spending, we get as,

1.5x + 2.25y = 1170 ...... (2)

solving (1) and (2) we get as,

Number of children were = 330

and Number of Adults were = 300

Answer:

6

Step-by-step explanation:

let’s start with putting the unknown to x, in this case it is the number.

5x-5=7+3x, so now we just solve this equation.

5x-3x=7+5

2x=12

x=6

Answer:

Constant of proportionality = 2.25

What this value means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25

Step-by-step explanation:

We are told that the daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat.

Let D be represent the daily fee and let the lent be L.

D ∝ L

Let the constant of proportionality be k.

Thus;

D = kL

k = D/L

For length of 15 ft;

k = 33.75/15

k = 2.25

For length of 17 ft

k = 38.25/17

k = 2.25

For length of 20 ft

k = 45/20

k = 2.25

Foe length of 21 ft

k = 47.25/21

k = 2.25

This means the formula for the relationship between the daily fee and boat length is; D = 2.25L

Thus, D/L = 2.25

What this means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25

Answer:

The first one will be 6. This is because 6/9 × 2/4= 1/3

Answer:7 is the exponent

Step-by-step explanation:

Answer:

[tex]6^7[/tex]

Step-by-step explanation:

Exponents can be expressed through repeated multiplication, meaning that the amount of times one number is being repeated, would be the same amount as put in an exponent. Therefore :

6 * 6 * 6 * 6 * 6 * 6 * 6

6 is being repeated, therefore it's the constant.

6 is repeated 7 times, therefore the exponent is 7.

Step-by-step explanation:

Answer:

Question 3: A

Question 4: C

Step-by-step explanation:

Answer:

The answer is k = 44.

Step-by-step explanation:

1) Subtract 3 from both sides.

[tex] \frac{k}{4} = 14 - 3[/tex]

2) Simplify 14 - 3 to 11.

[tex] \frac{k}{4} = 11[/tex]

3) Multiply both sides by 4.

[tex]k = 11 \times 4[/tex]

4) Simplify 11 × 4 to 44.

[tex]k = 44[/tex]

Therefor, the answer is k = 44.

Answer:

k = 44

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

k/4 + 3 - (14) = 0

                  k

Simplify   —

                  4

   k          

 (— +  3) -  14  = 0

   4

Adding a whole to a fraction

Rewrite the whole as a fraction using  4  as the denominator :

           3           3 • 4

   3 =  —  =  —————

           1               4  

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

       k + 3 • 4                    k + 12

—————————  =  ——————

            4                              4

       (k + 12)    

 ———————— -  14  = 0

            4

Subtracting a whole from a fraction

Rewrite the whole as a fraction using 4 as the denominator :

             14           14 • 4

   14 =  ——  =  ——————

              1                4

Adding up the two equivalent fractions

   (k + 12) - (14 • 4)              k - 44

——————————  =  ——————

             4                               4

      k - 44

 ——————  = 0

         4

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now, to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

   k - 44

 ———— • 4 = 0 • 4

      4  

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  k - 44  = 0

Solve  :    k - 44 = 0

Add  44  to both sides of the equation :

                     k = 44

8m= 36+20

m=56/8

=7 answer

Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)

m=(-5-6)/(9-(-3))

m=-11/12 so now we have

y=-11x/12+b, using point (9,-5) we can solve for b

-5=-11(9)/12+b

-5=-99/12+b

b=39/12

y=(-11x+39)/12

That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is

y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.

Answer:

January has the greater MAD.

Step-by-step explanation:

The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.

Answer:

3cm approx

Step-by-step explanation:

Given data

Volume=  72cm^3

Radius=3cm

Required the height

The expression for the volume is

Volume= πr^2h

substitute

72=3.142*3^2*h

72=28.278h

h= 72/28.278

h=2.54

Hence the height is 3cm approx
