Step-by-step explanation:

3. The length of the rectangle is 3x and width is x+5

Now,

Area of rectangle=l×b

=3x(x+5)

=3x^2+15x(option d.)

4. 2/3x-4=20

2x/3=20+4

2x/3=24

2x=24×3

2x=72

x=72/2

x=36(option d.)

Answer:

3. 3x^2 + 15x

4. x=36

Step-by-step explanation:

The area of a rectangle is

A = l*w

A = (3x)*(x+5)

Distribute

3x^2 + 15x

2/3x - 4 = 20

Add 4 to each side

2/3x -4+4 = 20+4

2/3x = 24

Multiply each side by 3/2

2/3*3/2 =24*3/2

x = 12*3

x=36

Answer:

2,850

Step-by-step explanation:

4.25 x 9 = 38.25

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

8.06 x 126 = 1015.56

all totals would equal 2,846.86, which to the nearest would be $2,850

lora16 [44]

Answer:

2.9 litres

2 14/15 litres

Step-by-step explanation:

To determine the amount of water Sam drinks in an hour, divide the total amount drunk by the number of hours

Amount drank in an hour = total litres drunk / time

$2\frac{1}{5}$ ÷ $\frac{3}{4}$

$\frac{11}{5}$ × $\frac{4}{3}$ = $\frac{44}{15}$ = 2 $\frac{14}{15}$ litres
