Answer: 28.8

Step-by-step explanation: first we find out 20 percent of 240=48

240-48=192 after discount

15 percent of 192= 28.8

Step-by-step explanation:

1.) 5x-4y=20

y=5/4x-5

5x/4-5=0

x=4

2.) 3x+3y=15

y=-x+5

x+5=0

-x=-5

=x=5

3.) y=3/4x-2

3/4x-2=0

x=0

3x4x/4 -2 x4x-0x4x

3-2x4x=0x4x

3-8x=0

8x=-3

=x=3/8

4.) y=3/2x+3

3/2x+3=0

x=0x

3x2x/2+3x2x=0x2x

3+3x2x=0x2x

3+6x=0

6x=-3

x=_3/6

=x=-1/2

Step-by-step explanation:

The answer of the following question is:

1)Find the total number of calories he burned out through the week that is

488+551+610+360+391=2700

which makes it 360/2700

Now we have to simplify

360/2700=36/270

36/270=18/135=6/45=2/15

so the final answer is :-

(c)2/15

Answer: The answer is given below

Step-by-step explanation: How are customary and metric the same?

The metric system uses units such as meter, litre, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces.

answer:

so the basic formula to find volume in shapes would be length × width × height.

here is a example : ( i cant really make the shape 3D so lets just say it is )

                5

and because i cant make the shape 3D, the width will be 2

all you really need to do is multiply all of them together, for smaller numbers you shouldn't have to really use your calculator ( if you have a pretty good memory of your times tables then you shouldn't have to as least ) but with bigger numbers then i would recommend using your calculator if your teacher does lets you  

5 * 3 * 2

= 30 units !

i hope this helps you and if you have anymore questions then please let me know! :)

Answer:

(3/2 m)^2 -(5n)^2^

Step-by-step explanation:

Answer: 9m^2 / 4  -  25n^2

Step-by-step explanation:

Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Answer:

36 hours

Step-by-step explanation:

300-30=270

270÷7.50=36

Answer:

36

Step-by-step explanation:

300 - 30 = 270

270 ÷ 7.50 = 36

To convert the fraction 2/4 to a decimal, we can perform the division 2 divided by 4 using long division or mental math.

2 ÷ 4 = 0.5

Therefore, 2/4 as a decimal is 0.5.

Answer:

B. 15g^2 + 35g^3 - 45g

Step-by-step explanation:

5g(3g + 7g^2 - 9)

5 x 3 = 15 g x g = g^2; 15g^2

5 x 7 = 35 g x g^2 = g^3; 35g^3

5g x -9 = -45g

Answer:

352.

y = 8c + 16d

Step-by-step explanation:

Expression:

c = cats

d = dogs

Expresion: y = 8c + 16d

Now use it by plugging in.

y = 8c + 16d

y = 8(16) + 16(14)

y = 128 + 224

y = 352 (that's how much he earned)

Answer:

(16 x $8) + (14 x $16)

Step-by-step explanation:

$8 for washing each cat

16 cats

16x$8           - Amount earned for washing cats

$16 for washing each dog

14 dogs

14x$16          - Amount earned for washing dogs

"Total earnings" = add them up

(16 x $8) + (14 x $16)

To determine the total cost of the game, we can set up an equation based on the given information.

Let's assume the total cost of the game is represented by the variable "x."

According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:

(2/3) * x = $18

To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:

(3/2) * (2/3) * x = (3/2) * $18

x = $27

Therefore, the game costs $27.

Question 1: 4 1/3

Question 2: -0.5

Question 3: 0.83

Did not specify how these should be done so First is Slope form, the rest are decimal.

Answer:

1)13/3

2)-1/2

3)5/6

Step-by-step explanation:

1) the negatives cancel

2)(3/4)/(9/16) --> (3/4)*(16/9) --> 4/3

3) (4/3) + (9/3) = 13/3

1)-6+4 = -2

2)-1+5 = 4

3)-2/4 --> -1/2

1)8-(5+(3(-4))) = 15

2)4^2 +2 = 18

3)15/18 --> 5/6

Negative 3, negative 2.4, negative 1.5, negative 2 and one-fourth, negative 1 and one-eighth

Hope my answer helps you✌️
