Titus and Theresa have collected money and are buying food for a dog shelter. Titus buys 2 bags and 5 cans of dog food, spending $17.50. Theresa buys 6 bags and 2 cans of dog food for $40.80. Let x represent the price of a bag of dog food and y represent the price of a can of dog food. Write a system of equations and use the elimination method to find a reasonable price for a can of dog food.


A)$0.90

B)$1.70

C)$6.30

D)$6.50

Answer:

x = 16.20

Step-by-step explanation:

tan48 = 18/x

xtan48 = 18

x = 18/tan48

x = 16.20

Answer:

Step-by-step explanation:

Y = 1/4x - 12

Adding 12 on both sides

12y = 1/4x

12y/ 1/4 = x

3y = x

messed up, thought it said 2 lol ignore my answer

Step-by-step explanation:

Consider AP:

As multiples of 5 between 100 and 300

The first term is 105, the common difference is 5, the last term is 295.

Use the nth term formula:

Answer:

Solution given:

first term [a]=100

last term[l]=300

common difference [d]=5

second term[b]=100+5=105

now

we have

l=a+(n-1)d

substituting value

300=100+(n-1)5

300-100=(n-1)5

200/5=n-1

40=n-1

n=40+1

there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple

Answer:

1) -10

2) 1

Step-by-step explanation:

1)  (-5) - 5

- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.

-5 -5 = -10

2) (-10) + 11

- The same case applies here since it is addition.

-10 + 11 = 1

Answer:

1) -10

2) -1

Step-by-step explanation:

[tex]( - 5) - 5 = - 10 \\ \\ ( - 10) + 11 = - 1 \: [/tex]

Answer: 2000

Step-by-step explanation:

From the information, we are informed that a population of 500 doubles in size every 80 years. Therefore, the population in 160 years will have doubled twice i.e 160/80 = 2 times

First time doubling = 500 × 2 = 1000

Second time doubling = 1000 × 2 = 2000

Answer:

Madison has earned 180 dollars in all.

Step-by-step explanation:

Let [tex]x[/tex] denotes amount earned by Madison.

Percentage of amount saved by Madison [tex]=\frac{40}{100} x[/tex]

Amount saved by Madison [tex]=72[/tex] dollars

Therefore,

[tex]\frac{40}{100}x=72\\x=72(\frac{100}{40})[/tex]

[tex]=180[/tex] dollars

So,

Madison has earned 180 dollars in all.

Answer:

y= 2x+1

Step-by-step explanation:

Using the general linear form y=mx+c

First find the gradient: change in y/change in x

11-5/6-2 = 6/3= 2

y=2x+c

Secondly find out c:

Use one of the coordinats

5= 2(2)+c

5=4+c

-4

1=c

y= 2x+1

I have attached an image of the triangle.

BC = 9 cm

Answer:

CE = 7.2 cm

Step-by-step explanation:

In the attached triangle, we see that;

AB = AC = 7.5cm

BC = 9 cm

AD = 6cm

BC = 9cm

Formula for area of triangle is given as;

A = ½bh

Where b is base and h is height.

For the ∆ ABC with BC as base,

Area = ½ × 9 × 6 = 27 m²

Similarly, For ∆ ABC with AB as base,

Area = ½ × 7.5 × CE

Now, area from earlier is 27 cm²

Thus;

½ × 7.5 × CE = 27

Multiply both sides by 2 to get;

7.5CE = 54

CE = 54/7.5

CE = 7.2 cm

Answer:

Step-by-step explanation:

3y = -x + 6

y = -1/3x + 2

y - 3 = -1/3(x + 1)

y - 3 = -1/3x - 1/3

y - 9/3 = -1/3x - 1/3

y = -1/3x + 8/3

Answer:

23.41%

Step-by-step explanation:

Kirtim's purchase price was 3600 + 205 = 3805,

Kirtim sold the table for 4968 for a profit of 4968 - 3805 = 1163

Assuming requirement is for profit on revenue, so

P = 100 * (1163/4968) = 23.41%

Answer:

the x would equal to 11 ,so x=11

Answer:

Option (3)

Step-by-step explanation:

Formula to calculate the surface area of a cardboard box in the shape of a cube is,

Surface area = 6(Side)²

If the length of the each side of the box is = 3 feet

Surface area of the cube = 6(3)²

                                          = 6 × 9

                                           = 54 square feet

Therefore, Surface area of the box in the shape of a cube is 54 square feet.

Option (3) is the correct option.

Answer:

hii

Step-by-step explanation:

interior corner of the triangle is 180°

180° - 78° - 90° = 12°

x = 12°

2y - 1 = 24

2y = 24 + 1

y = 25/2

y = 12.5

Answer:

c.15

Step-by-step explanation:

3*35= 105

since 7x=105 you divide 105 by 7 which is 15

Answer:

7x=3y

7x=3(35)

7x=105

x=105/7

x=15

Answer:

25 I'm pretty sure

Step-by-step explanation:

5×5=25

Answer:

25 cm

Step-by-step explanation:

If it is enlarged by the scale factor of 5, you are multiplying by 5. 5 cm is the longest side, so therefore 5 cm times 5 cm is equal to 25.

Answer:

35

Step-by-step explanation:

When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.

So, x + 12 + 4x - 7 = 180.

5x + 5 = 180

5x = 175

x = 35
