Answer:

it's $30 I just know trust meO_o

Step-by-step explanation:

have an amazing day luv

Answer:

10 students would pay for lunch with $30.

Step-by-step explanation:

This is how I know $30 is the correct answer:

1. To figure out how much money it would cost for 1 student I would take the $12 the four students paid for lunch and divide it by 4 so we would know the exact cost for one students lunch (12/4=3 or $3)

2. Now we know $3 is the cost for 1 student. We can now multiply the $3 by 10 (students) so we can get the cost for 10 lunches (3(10)=30 or $30)

3. We got our final answer of $30=10 students lunches.

I hope this helps:)

Answer:

Answer=

x=(-2),y=(-4)

and in components form,

(-2,-4)

Step-by-step explanation:

equation1 (-2x+2y=-4)

equation2 (3x+3y=-18)

(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)

E1 (-6x+6y=-12)

E2 (6x+6y=-36)

(subtract both equations from each other)

-6x+6y=-12

-

6x+6y=-36

=(-12x=24)

so, x=24÷-12=-2

(then we sub the value of x into one of the equations- the new one or the old one)

3x+3y=-18

(3×-2)+3y=-18

3y=-18+6=-12

y=-12÷3=-4

The answer is "0.96562".

Step-by-step explanation:

please find the complete question which is defined in the attached file.

Given value:

[tex]\to p = 0.42 \\\\\to q = 1 - p[/tex]

      [tex]= 0.58[/tex]  

[tex]\to n = 400\\\\\to x = 150 \\\\\to P = \frac{X}{n}\\[/tex]

        [tex]= \frac{150}{400}\\\\ = 0.377[/tex]

When:

   [tex]\to P(P>0.375)\\\\[/tex]

[tex]=P(\frac{P-p}{\sqrt{ \frac{pq}{n}}}>\frac{0.375-0.42}{\sqrt{\frac{0.42 \times 0.58}{400}}})[/tex]

[tex]=P(Z>-1.82) \\\\=1-P(Z>1.82)\\\\=1-0.034380\\\\ =0.96562[/tex]

Step-by-step explanation:

Trust me, i took the test.

Answer:  x = 480

Steps: x/2.4 + 39 = 239

Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39

Simplify: x/2.4 = 200

Multiply both sides by 2.4: x/2.4  ×  2.4 = 200 ×  2.4

Simplify: x = 480

Answer:

C. 4.2 pounds Brand A. 0.8 pounds Brand B

Step-by-step explanation:

How much of each brand of coffee is needed to make 5 pounds that will cost

$6.75/pound?

Let the number of pounds for Brand A = x

Let the number of pounds for Brand B = y

Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.

$7 × x + $5.40 × y = $6.75 × 5

7x + 5.40y = 33.75.......Equation 1

x + y = 5 .......Equation 2

x = 5 - y

7(5 - y)+ 5.40y = 33.75

35 - 7y + 5.40y = 33.75

35 - 33.75 = 7y - 5.40y

= 1.25 = 1.6y

y = 1.25/1.6

y = 0.78125 pounds.

Approximately to the nearest whole number, Brand B = 0.8 pounds.

x = 5 - y

x = 5 - 0.8 pounds

x = 4.2 pounds

Brand A = 4.2 pounds

Answer:

Step-by-step explanation:

Answer:

12.9

Step-by-step explanation:

A square has even lengths on each side. Since there is 4 sides on a square. We divide perimeter by 4.

51.6/4 = 12.9 inches

The length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.

A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles.

The perimeter of a square is the sum of the lengths of all its sides.

Let a be the length of each side of the square, then the perimeter P is given by:

P = 4a

We are given that the perimeter is 51.6 inches, so we can set up the equation:

51.6 = 4a

Solving for a, we divide both sides by 4:

a = 51.6/4

a = 12.9

Therefore, the length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.

Answer:

Your answer should be 8g^15

Step-by-step explanation:

If cubed (power of 3) is on a parenthesis, that means you have to cube every expression inside that parenthesis. In order to distribute exponents, mutliply them. This gives you g^5 times ^3, which is g^15. ^3 has to also be distributed to the 2, which is 2^3 = 8. 8 and g^15 is 8g^15.
