Answer:

20

Step-by-step explanation:

She volunteers for hours on each week day = 2

No. of week days = 5

So, She volunteers for hours on 5 week day = 5 \times 2

On Saturday and Sunday, she volunteers 3 hours more each day.

So, on weekend She volunteers for hours on each day = 2+3 = 5 hours

No. of days in weekend = 2

So, She volunteers for hours on weekend 2 \times 5

So,  the number of hours she volunteers in one week:

=  5 \times 2+2 \times 5

= 20

Hence the number of hours she volunteers in one week is 20

HELPPP MEEE PLZZ ok so If i have 70$ dollars the amout is just right so i can buy 4kg of fish and 3kg of prawn so i bought it an
Kaylis [27]

Answer:

x = (66.50 - 4y) / 3

Step-by-step explanation:

Given that:

Amount had = $70

Change collected = $3.50

Total amount spent = $(70 - 3.50) = $66.50

Total amount used for purchasing prawn and fish:

Kg of fish = 4

Kg of prawn = 3

1 kg prawn will cost, x

If 1 kg of fish = y

(Total amount spent - cost of 4 kg fish) / Number of kg of prawn

($66.50 - 4y) / 3

x = (66.50 - 4y) / 3

Find the equation of the line parallel to x+3y = 4 and passing through the point (2, 5)
dmitriy555 [2]

Answer:

The equation of the parallel line is x + 3y = 17

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercept

The form of the equation y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept

∵ The equation of the given line is x + 3y = 4

→ We must put it in the form above to find its slope

→ Subtract x from both sides to move x to the right side

∵ x - x + 3y = 4 - x

∴ 3y = 4 - x

→ Divide both sides by 3 to make the coefficient of y = 1

∴ \frac{3y}{3}=\frac{4}{3}-\frac{1}{3}x

∴ y = \frac{4}{3} -  \frac{1}{3} x

→ Compare it with the form of the equation above

∴ m = -\frac{1}{3}

∵ Parallel lines have the same slopes

∴ The slope of the parallel line is -\frac{1}{3}

→ Put it in the form of the equation

∴ y =  -\frac{1}{3} x + b

→ To find b substitute x and y in the equation by the coordinates

   of a point on the line

∵ The line passes through the point (2, 5)

∴ x = 2 and y = 5

→ Substitute them in the equation

∴ 5 =  -\frac{1}{3} (2) + b

∴ 5 =  -\frac{2}{3} + b

→ Add  \frac{2}{3}  to both sides

∴ \frac{17}{3} = b

→ Substitute it in the form of the equation above

∴ y = -\frac{1}{3} x + \frac{17}{3}

→ Multiply each term by 3

∴ 3y = - x + 17

→ Add x to both sides

∴ x + 3y = 17

∴ The equation of the parallel line is x + 3y = 17
