                                            =356 students

 students who did not have lunch=5/5-2/5

                                                         =3/5*890

                                                        =534 students

14)a)4pens=180 cents

       2 books=5.3$

      total=7.1 US$

b)5 pens=225 cnets

   3 books=7.95 US$

  total=10.2 US$

10)ate=1 over 8

    remaining=8/8-1/8

                     =7/8

after six hours=7/8*2/5

                        =7 over 20

total ate=1/8+7/20

            =14+5 over 40

           =19 over 40

remaining=40 over 40 - 19 over 40

                =   21 over 40

to dog=21/40 *1/4

          =21 over 160

total=19 over 40 +21 over 160

        =152+21 over 160

         =173  over 160

Answer:

a + 4(n-1)

Step-by-step explanation:

The first term is a+4, the second term is a+8, the third term is a+12, etc.

A common theme that we can notice is that we add 4 for each term. For example, the second term (t₂) equals t₁+4, the third term equals t₂+4 (as a+4+4 = a+8), and so on. Another way of writing this is that we multiply 4 by (term number - 1) and add that to a. We can write this as

4 * (n-1) + a

  x = -3

Step-by-step explanation:

Undo the addition of -6 by adding the opposite of that to both sides of the equation.

  x + (-6) +(+6) = (-9) +(+6)

  x = -3

Answer:

[tex]2.6\frac{feet}{step}[/tex] or 2.6 ft/step

Step-by-step explanation:

In order to find the average number of feet traveled per step, divide the total number of feet traveled by the total number of steps taken:

[tex]\frac{13 feet}{5 steps}=\frac{13}{5}\frac{feet}{step}=2.6\frac{feet}{step}[/tex]

Therefore, for each step taken 2.6 feet are traveled (on average). We can say this as 2.6 feet per step or 2.6 ft/step.

Answer:

7/3 =k

Step-by-step explanation:

4. -7 = 3k - 3-7

Combine like terms

-3 = 3k-10

Add 10 to each side

-3+10 = 3k-10+10

7 = 3k

Divide each side by 3

7/3 = 3k/3

7/3 =k

Answer:

7/3

Step-by-step explanation:

4 - 7 = 3k - 3-7    

=> -3 = 3k - 10    

=> -3 + 10 = 3k  

=> 7 = 3k    

=> 7/3 = k

=> k = 7/3

2) (f - g ) x = (x²-4) – (x+2) = (x²-4)+ ( -x - 2) = x²–x–6

3) (f × g ) x = (x²-4)(x+2) = x³+2x²– 4x – 8

4) (f / g) x = (x²-4) / (x+2) = x – 2

5) ( f + g ) 4 = (x²-4)+ (x+2) = ((4²)-4)+ (4+2) = ( 16–4) + (6) = 12+6 = 18

Answer:

x = –2/3 or –20/9

Step-by-step explanation:

(9x+13)² = 49

Finding the square root of both sides

9x+13 = √49

9x+13 = ±7

Subtracting 13 from both sides

9x = 7 – 13 or 9x = -7 –13

9x = –6 or 9x = –20

Divide both sides by 9

x = –6/9 or x = –20/9

Simplifying

x = – 2/3 or x = –20/9

Answer:

x=4

Step-by-step explanation:

Simplifying

-1(7 + -4x) = 9

(7 * -1 + -4x * -1) = 9

(-7 + 4x) = 9

Solving

-7 + 4x = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7' to each side of the equation.

-7 + 7 + 4x = 9 + 7

Combine like terms: -7 + 7 = 0

0 + 4x = 9 + 7

4x = 9 + 7

Combine like terms: 9 + 7 = 16

4x = 16

Divide each side by '4'.

x = 4

Answer:

x = 4

Step-by-step explanation:

-(7 - 4x) = 9             (Given)

-7 + 4x = 9              (Distributed)

-7 + 4x + 7 = 9 + 7  (Add 7 on both sides)

4x = 16                    (Simplify)

4x/4 = 16/4             (Divide 4 on both sides)

x = 4                       (Simplify)

Answer:

2/3 quarts

Step-by-step explanation:

Paint used by 9 artists = 6 quarts

So, paint used by 1 artist if shared equally among the 9 artists

= 6 quarts/9

= 2/3 quarts

= 0.6666...... quarts

Rounding to the nearest hundredth, each artist would get approximately 0.67 quarts of paint.

To determine how many quarts of paint each artist gets when six quarts of paint are equally shared among nine artists, we can divide the total amount of paint by the number of artists. 6 quarts ÷ 9 artists = 0.6667 quarts per artist

To "equally share" means to divide or distribute something equally among a group of individuals or entities. It implies that each person or entity involved receives an equal portion or share of the item being distributed. This division ensures fairness and equal opportunities for everyone involved. The goal is to ensure that each recipient receives an equal amount or proportion of the item being shared.

16 - 2.2 is the question.

WE can split this problem up into 2.

16 - 2 and 1 - 0.2.

16 -2 = 14

1 - 0.2 = 0.8

Answer:

  D. m∠C=63, b=28.1, c=25.1

Step-by-step explanation:

The angle sum relation tells you ...

  C = 180° -23° -94° = 63°

The law of sines tells you ...

  b/sin(B) = a/sin(A)

  b = sin(B)·a/sin(A) = sin(94°)·11/sin(23°) ≈ 28.084 ≈ 28.1

Similarly, ...

  c = sin(C)·11/sin(23°) = sin(63°)·28.15235 ≈ 25.084 ≈ 25.1

__

  C = 63, b = 28.1, c = 25.1
