Answer:     Tahat= 40.5 marks    Promi =29.5 marks,  Kabi =24.5 marks

Step-by-step explanation:

Step 1

Let the marks be represented as  x+11, x and x-5 for Tahat, Promi and Kabi respectively

and Tahat's marks which was 75% of the sum of Promi and Kabi's marks be expressed as

x+11 = 75/100(x + x-5)  

Step 2 --- Solving

x+11 = 75/100(x + x-5)  

x+ 11 = 3/4(2x-5)

x+11= 6x-15/4

4x+44=6x-15

44+15=2x

x= 59/2= 29.5,

A) x= Promi's  mark was 29.5

B)Promi secured 5 marks more than kabi

Therefore, Kabi's mark was 5 marks less than Promi

= x-5

29.5- 5= 24.5 marks

C)Promi secured 11 marks less than Tahat, Therefore Tahat marks were 11 marks more than Promi

x+11= 29.5 + 11= 40.5

Answer:

Danny contributed $295

Step-by-step explanation:

Assume that Danny contributed $x

∵ Danny contributed x

∵ Beth contributed $80 more than Danny

→ Add The amount of Danny by $80 to get the amount od Beth

∴ Beth contributed x + 80

∵ Katie contributed $20 less than Beth

→ Subtract the amount of Beth by 20 to get the amount of Katie

∴ Katie contributed x + 80 - 20

∴ Katie contributed x + 60

∵ The three friends pay $1025

→ Add their amounts and equate the sum by 1025

∴ x + x + 80 + x + 60 = 1025

→ Add the like terms in the left side

∵ (x + x + x) + (80 + 60) = 1025

∴ 3x + 140 = 1025

→ Subtract 140 from both sides

∴ 3x + 140 - 140 = 1025 - 140

∴ 3x = 885

→ Divide both sides by 3

∴ x = 295

∵ x represents the amount of Danny contributed

∴ Danny contributed $295

After 11 months, Stacy will have $81 in her savings account.

Step-by-step explanation:

15 + 6m = 81

6m = 66

m = 11

Answer:

the answer is b

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given equation is,

y = 3x² - 6x + 11

a). y = 3x² - 6x + 11

       = 3(x² - 2x) + 11

       = 3(x² -2x + 1 - 1) + 11

       = 3(x² - 2x + 1) - 3 + 11

       = 3(x - 1)² + 8

Comparing this equation with y = a(x - b)² + c

a = 3, b = 1 and c = 8

b). For minimum value of x,

    Since, vertex of the graph is given by (b, c),

    Minimum value of x will be,

    x = b

    x = 1

c). Vertex of the parabola → (b, c)

                                           → (1, 8)

    For y-intercept,

    By substituting x = 0 in the equation,

    y = 3(0 - 1)² + 8

    y = 11

Now we can sketch the graph by using the table of input - output values.

x         -2        -1           0            1             2          3

y        35        20         11           8            11         20  

Answer:

The answer is -300

Step-by-step explanation:

The answer is -300 because -2 multiplied by 6 is -12 and -12 times 25 is -300

Answer:

The bottle will last for 20 days.

Step-by-step explanation:

Given that:

Number of drops in a dose = 4 drops

Dose is taken three times a day, therefore,

Number of drops taken in a day = 4*3 = 12 drops

One milliliter = 20 drops

12 mL = 20*12 = 240 drops

Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.

Number of days bottle will last = [tex]\frac{240}{12}=20[/tex]

Hence,

The bottle will last for 20 days.

Answer:

h = no solution

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

5h + 10 = 5h + 15

Step 2: Solve for h

Here we see that 10 does not equal 15.

∴ h has no solution.

Final Answer: No Solution

Steps/Reasons:

Step 1: Simplify [tex]4h + h + 15[/tex] to [tex]5h + 15[/tex].

[tex]5h + 10 = 5h + 15[/tex]

Step 2: Cancel [tex]5h[/tex] from both sides.

[tex]10 = 15[/tex]

Step 3: Because [tex]10 = 15[/tex] is false, there is no solution.

No Solution

Answer:

x=2

Step-by-step explanation:

2x+x+3=9

2x+x=9-3

3x=9-3

3x=6

x=2

Answer:

a) 2x + 3 = -x + 9

or, 3x = 6

# x = 2 since there is no y in the equation the value of y could be 0.

b) it intersects at ( 2, 0 )

Answer:

                              126

                    P = -------------

                              2 - r

Step-by-step explanation:

Solve for P:  P(2-r)-17=109

Combining the constant terms:

                     P(2 - r) = 126

Dividing both sides by (2 - r) isolates P:

                              126

                    P = -------------

                              2 - r
