How many solutions are there to the following equation?
5 ( x-3 ) - 3x = 8x - 15 - 6x

A) exactly two solutions
B) exactly one solution
C) no solution
D) infinitely many solutions

Answer:

$1.75

Step-by-step explanation:

Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:

3x + y = 7.1

2x + 2y = 7.2

Solve by elimination by multiplying the top equation by -2

-6x - 2y = -14.2

2x + 2y = 7.2

Add them together:

-4x = -7

x = 1.75

So, the cost of one corndog is $1.75

Answer:

9

Step-by-step explanation:

For this, we need to know the scale factor first. We can do that by looking at a same side of the two shapes.

CD = 2 and ML = 3.6

3.6 / 2 = 1.8

just to confirm, let's take MN = 7.2 and DE = 4

7.2 / 4 = 1.8

So now we know the scale factor is 1.8

Now to figure out x, we just need to use BA = 5

and because the scale factor is 1.8

so we just need to do: 5 * 1.8 = 9

40-26=14 so therefore 14% of the books are non-fiction

Answer:

10 i guess

cause

8*3=24

3*10=30

Step-by-step explanation:

Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)

Therefore 3x = 30 and x = 10.

Answer:

D

Step-by-step explanation:

Answer: 4

Step-by-step explanation: 20-10=10 which is %50. 20-16=4

Answer:

Step-by-step explanation:

it means the ABC And DEF have side lengths of 15,19, 25

so 3x-3 = 15

x = 6

5-y = 19

so y = -14

Answer:

1. D

2. y = 15.50x + 450

Step-by-step explanation:

1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.

2. x  > (y - 450)/ 15.50

i) Rita gets paid $450 per week.

ii) She gets $15.50 for every new membership she sells.

iii) let y represent the total pay per week.

iv) let x represent the number of new memberships sold.

v) the equation representing total pay is y = 15.50x + 450.

vii) therefore the equation that represents a higher rate of membership sold is given by  x  > (y - 450)/ 15.50

The height of the triangle is 0.00625.The correct option is D

A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.

Let h represent the triangle's height. The triangle's area is then:

1 = (1/2)320h

calculating h:

h = 1 / (320/2) = 0.00625

Therefore, option D is appropriate because the triangle's height is 0.00625.

Answer:

Here, for example, is square inch pricing, using a multiplier of 2.5 (ie, $2.50 per square inch):

4×4 inches = 16 square inches x 2.5 = $40

8×8 inches = 64 square inches x 2.5 = $160

16×16 inches = 256 square inches x 2.5 = $640

24×24 inches = 576 square inches x 2.5 = $1,440

32×32 inches = 1,024 square inches x 2.5 = $2,560

I don’t know about you, but $40 seems awfully small price for a painting by someone who commands $2,560 for a 32×32 canvas.

Here are the same canvas sizes using linear inch pricing, using a multiplier of 20 (ie, $20.00 per linear inch) — as you can see, the difference in price feels a lot less out-of whack:

4+4 inches = 8 linear inches x 20 = $160

8+8 inches = 16 linear inches x 20 = $320

16+16 inches = 32 linear inches x 20 = $640

24+24 inches = 48 linear inches x 20 = $960

32+32 inches = 64 linear inches x 20 = $1,280

Neither of these pricing methods is “right” or “wrong,” but once you determine your method and your multiplier, charging by size can be a very helpful way to eliminate the guesswork, and feel confident about your pricing.

Different Pricing for Different Media?

One possible modifier to your size-based pricing structure is the media you paint with. If you only paint watercolors, or only paint oils, there’s no problem, but if you paint both on canvas and on paper, as I do, it gets a little tricky.

For whatever reason, paintings on paper tend to sell for less than paintings on canvas — even though they require framing, which is an added expense. In my case, if I were to pay to have a piece framed, my costs become much higher for a work on paper than for a canvas painting! What’s an artist to do?

(And remember that pricing your prints is an entirely different topic.)

Answer:

The answer should be 14/15.

Step-by-step explanation:

The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.

Then you add both of them together.

-6/15 + 20/15 = 14/15

Answer:

The answer is t.

Step-by-step explanation:

We need to find the sum of opposite of - 10t and t - 10t.

Opposite of -10t = 10 t

So,

10t + (t-10t)

Grouping the numbers,

(10t+(-10t)) + t

= 0 + t

= t

Hence, the answer is t.

Peter signed up for a program that costs $10.50 per month to stream movies to his computer.

He decided to cancel his service after 5/6 month

So,has to pay for the amount of time he used the service:

$10.50 • 5/6 = $1.75 • 5 = $8.75

The amount of money peter has after paying for the service is

$10.50 - $8.75 = $1.75

Answer:

(3, -3)

Step-by-step explanation:

A point qualifies as a solution to a system of inequalities if it is true when both of its x and y values are substituted into the both inequalities. Knowing this, let's plug in the first option, (3, -3), into both inequalities.

Let's try 6x + 3y > 3 first. Substitute 3 for x and -3 for y:

[tex]6 (3) + 3 (-3) > 3\\18 - 9 > 3\\9 > 3[/tex]

9 is bigger than 3, so (3, -3) is a solution to that inequality.

Let's try [tex]x -y \geq 4[/tex]. Do the same, substituting the same values:

[tex]3 - (-3) \geq 4\\3 + 3 \geq 4\\6\geq 4[/tex]

6 is bigger than 4, so (3, -3) is a solution to that inequality too.

Since (3, -3) is a solution to both inequalities, it must be the answer.

Answer:

the last option is the right answer

Step-by-step explanation:

last week:

d = 18

d = 18h = 6

this week:

d = 2.5h

i. if she walked for 6 hours this week, h = 6

d = 2.5h

d = 2.5 × 6

d = 15

* this means she walked at slower pace this week as she can only cover 15 miles in 6 hours whereas she can cover 18 miles in 6 hours last week

ii. if she walked for 18 miles this week, d = 18

d = 2.5h

18 = 2.5h

h = 18/ 2.5

h = 7.2

* this means she walked at a slower pace this week as she needs 7.2 hours to cover 18 miles whereas she only need 6 hours last week
