Sam bought 6 pens for an unknown price plus a

backpack. If he spent a total of $28.50, write an

equation to find the cost of each pen.

so sam bought SIX pens for a TOTAL of $28.50. we have to figure out how much money each of the six pens cost.

steps:

1. divide the total by the amount of items purchased:

28.50 / 6 = 4.75

and there’s your answer! each pen cost $4.75

steps to check your work:

1. multiply the single cost by the amount of items purchased:

4.75 ( 6 ) = 28.50

steps:

1. divide the total by the amount of items purchased:

28.50 / 6 = 4.75

and there’s your answer! each pen cost $4.75

steps to check your work:

1. multiply the single cost by the amount of items purchased:

4.75 ( 6 ) = 28.50

If a rectangle measures 21 centimeters by 28 centimeters what is the length in centimeters of the diagonal of the rectangle

Answer:

**35cm**

Step-by-step explanation:

Given data

Length= 21cm

Width= 28cm

Diagonal= ???

Applying Pythagoras theorem

D^2= L^2+W^2

D^2= 21^2+28^2

D^2= 441+784

D^2= 1225

D= √1225

D= 35cm

**Hence the diagonal is 35cm**

Solve this system of equations.Write your answer as an ordered pair.3x+4y=36 y=-1/2x+8

**Answer:**

x = 4

y = 6

**Step-by-step explanation:**

[tex]\left \{ {{3x+4y=36} \atop {\frac{1}{2}x+4y=8 }} \right.[/tex] rewrite the equations and multiply bottom equations by -4

[tex]\left \{ {{3x+4y=36} \atop {-2x-4y=-32}} \right.[/tex] add both equations together

x = 4

then, input x=4 into equation 3x+4y=36:

3(4)+4y=36 (simplify)

12+4y=36 (subtract 12 from both sides)

4y=24 (divide both sides by 4)

y=6

Answer:

Step-by-step explanation:

2(2x +4) - 2x = x + 18

4x +8 -2x = x +18

2x -x = 18-8

X = 10

Put the value of x in both side

Left side *+*+*+*+*+

2 ( 2*10+4)-2*10

48-20 = 28

Right side +*+*+*+*+*

X + 18

Y=-x-2

2x-3y=-9

Solve for x and y

**Answer:**

y = - x - 2

2x - 3y = - 9

put value of y

2x - 3(-x - 2)= -9

2x +3x +6 = - 9

5x = - 9 - 6

5x = - 15

x = - 3

now put x in y = - x - 2

y = - (-3)-2

= 3-2

**Answer:**

2[tex]x^{2}[/tex] + 9x - 5 = 0

**Step-by-step explanation:**

// Use the Vijet's theorem,

// note that the kofficient before [tex]x^{2}[/tex] = 1

Sum of the roots is:

1/2 + (-5) = - 4,5

Product of the roots is:

0,5 * (-5) = - 2,5

Formation of quadratic equation:

[tex]x^{2}[/tex]** - (sum of the roots) x + product of the roots = 0 **

[tex]x^{2}[/tex] - (-4,5) * x + (-2,5) = 0

[tex]x^{2}[/tex] + 4,5x -2,5 = 0

// multiply both sides by 2

2[tex]x^{2}[/tex] + 9x - 5 = 0

five litres of paint costs R575 .Work out the cost of fifteen litres of paint

**Answer:**

first of all learn how to spell liters

1725

**Step-by-step explanation:**

**15 liters** of pain will cost Rs.225

**Multiplication** is a process of adding a number repetitively. Mathematically, we can write -

m = a x b

Given is that the 5 liters of paint costs Rs. 75.

5 liters of paint costs Rs. 75.

1 liter of paint will cost Rs. (75/5)

**15 liters** of pain will cost Rs. (75/5 x 15) = 75 x 3 = **Rs. 225**

Therefore, **15 liters** of pain will cost Rs.225

Determine the intercepts of the line:

y = -9x - 14

Answer: (-14/9, -14) or (-1.5, -14)

Step-by-step explanation:

y = -9x - 14

the coefficient without a variable in a slope-intercept equation is the y-intercept -- in this case, it is -14

to find the x intercept you use the equation given, set y to equal zero and Solve for x

- Your new equation should be: 0 = -9x - 14

Our new goal is to isolate the x

Start by doing the inverse of the coefficient, so add 14 to both sides

- Your new equation should be: 14 = -9x

Theres still a -9 attached to the x and the -9 is attached by multiplication -- so now you do the inverse function and divide both sides by -9

Your final answer: -14/9 = x or -1.5 with a repeating decimal

the sum of the number and 5 is 12

**Answer:7**

**Step-by-step explanation: x+5=12 solve for x = 7**

Answer:

"a number" = 7

Step-by-step explanation:

let "a number" = x.

x + 5 = 12

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides.

x + 5 (-5) = 12 (-5)

x = 12 - 5

x = 7
