Answer:

A pound of potato costs $3.10

A dozen egg costs $5.5

A wheel of cheese costs $6.25

Step-by-step explanation:

Represent

- a dozen egg with D

- a wheel of cheese with W

- a pound of potato with P

For Adam:

[tex]3D + W + 5P = 38.25[/tex] ---- (1)

For Barry:

[tex]D + 10P = 36.50[/tex] ---- (2)

For Charles:

[tex]2D + 2P = 17.20[/tex] ---- (3)

Make D the subject in (2)

[tex]D = 36.50 - 10P[/tex]

Substitute 36.50 - 10P for D in (3)

[tex]2(36.50 - 10P) + 2P = 17.20[/tex]

[tex]73 - 20P + 2P = 17.20[/tex]

[tex]73 - 18P= 17.20[/tex]

Collect Like Terms

[tex]- 18P= 17.20 - 73[/tex]

[tex]- 18P= -55.8[/tex]

[tex]18P= 55.8[/tex]

Solve for P

[tex]P = 55.8/18[/tex]

[tex]P = 3.1[/tex]

Substitute 3.1 for P in [tex]D = 36.50 - 10P[/tex]

[tex]D=36.50 - 10 * 3.1[/tex]

[tex]D=36.50 - 31[/tex]

[tex]D=5.5[/tex]

Substitute 3.1 for P and 5.5 for D in [tex]3D + W + 5P = 38.25[/tex]

[tex]3(5.5) + W + 5(3.1) = 38.25[/tex]

[tex]16.5 + W + 15.5 = 38.25[/tex]

Solve for W

[tex]W = 38.25 - 16.5 - 15.5[/tex]

[tex]W = 6.25[/tex]

Answer:

4 and -5

Step-by-step explanation:

Minus times minus equals positive, therefore, the two numbers that will give 20 when multiplied, -12 when added up are: -10 and -2.

As a law of operation in mathematics, when two negative numbers are multiplied, the result will always be positive. - × - = +.

Thus, we would have:

-10 × -2 = 20

-10 + (-2) = -12

Therefore, two numbers that will give 20 when multiplied, and would also add up to give -12 are: -10 and -2.

Answer:

c.  19,712

Step-by-step explanation:

2,816 * 7 = 19,712

To solve this problem you must apply the following proccedure:

1. You have a total of 21 coins, all nickels and dimes. Then:

x:nickels=5 cents

y: dimes=10 cents

x+y=21

2. You have that the total value is $1.70. Then:

5x+10y=170

3. The system of equation is:

x+y=21    (i)

5x+10y=170    (ii)

4. You have:

x+y=21

x=21-y

5(21-y)+10y=170

105-5y+10y=170

y=13 dimes

x+13=21

x=8 nickels

Let, she sold x and y numbers of succulent and ivy plants.

So,

x + y = 34      ...1)

12x + 4y = 240      ...2)

Putting value of x from 1) to 2), we get :

12( 34 -y ) + 4y = 240

408 - 12y + 4y = 240

8y = 168

y = 21

x = 13

Therefore, she sell 13 succulent and 21 ivy plants.

Hence, this is the required solution.

Answer:

44 pounds

Step-by-step explanation:

We are told that;

1kg = 2.2 pounds.

Now, the pen pal wrote that his dog weighs 20 kilograms.

Thus, the dog's weight in pounds will be gotten by proportion as;

Weight = (20 kg × 2.2 pounds)/1 kg

Weight = 44 pounds

Therefore, the dog weighs 44 pounds

Answer:

y = 3

Step-by-step explanation:

We need to solve the below proportion in this problem,

[tex]\dfrac{9}{2}=\dfrac{27}{2y}[/tex]

First of all, we cross multiply both sides such that,

[tex]9\times 2y=27\times 2\\\\18y=27\times 2[/tex]

Dividing both sides by 18.

[tex]y=\dfrac{27\times 2}{18}\\\\y=3[/tex]

For the above proportion, we find that the value of y is equal to 3.

Answer:

[tex]y = \frac{7}{4}x +14[/tex]

Step-by-step explanation:

Given

[tex]y = \frac{7}{4}x + 4[/tex]

Required

Determine the equation of line that passes through (-8,0) and parallel to [tex]y = \frac{7}{4}x + 4[/tex]

Parallel lines have the same slope.

In [tex]y = \frac{7}{4}x + 4[/tex]

The slope, m is

[tex]m = \frac{7}{4}[/tex]

because the general form of a linear equation is:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

So, by comparison:

[tex]m = \frac{7}{4}[/tex]

Next, is to determine the equation of line through (-8,0)

This is calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = \frac{7}{4}[/tex]

[tex](x_1,y_1) = (-8,0)[/tex]

So, we have:

[tex]y - 0 = \frac{7}{4}(x -(-8))[/tex]

[tex]y - 0 = \frac{7}{4}(x +8)[/tex]

[tex]y - 0 = \frac{7}{4}x +\frac{7}{4}*8[/tex]

[tex]y - 0 = \frac{7}{4}x +7*2[/tex]

[tex]y - 0 = \frac{7}{4}x +14[/tex]

[tex]y = \frac{7}{4}x +14[/tex]
