Step-by-step explanation:

From y=2x-5, gradient=2

<u>C</u><u>h</u><u>a</u><u>n</u><u>g</u><u>e</u><u> </u><u>i</u><u>n</u><u> </u><u>y</u><u> </u>= Gradient

Change in x

<u>8</u><u>-</u><u>4</u><u> </u>=2

6-n

4 = 2(6-n)

4 =12 -2n

4 - 12 = -2n

-8 = -2n

<u>-</u><u>8</u> =n

-2

n= 4

2 doctors is what % of 25 doctors
Elanso [62]

For this case we propose a rule of three:

25 ------------> 100%

2 --------------> x

Where the variable "x" represents the percentage equivalent to 2 doctors.

x = \frac {2 * 100} {25}\\x = 8

Thus, 2 doctors represent 8% of 25

Answer:

2 doctors represent 8% of 25

Help me with this question <br> Please I need help

Answer:

384 cm²

Step-by-step explanation:

The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.

To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:

For parallelogram:

Height (H) = 7.5 cm

Base (B) = 24 cm

Area of parallelogram (A₁) =?

A₁ = B × H

A₁ = 24 × 7.5

A₁ = 180 cm²

For rectangle:

Length (L) = 24 cm

Width (W) = 8.5 cm

Area of rectangle (A₂) =?

A₂ = L × W

A₂ = 24 × 8.5

A₂ = 204 cm²

Finally, we shall determine the area of the shape.

Area of parallelogram (A₁) = 180 cm²

Area of rectangle (A₂) = 204 cm²

Area of figure (A)

A = A₁ + A₂

A = 180 + 204

A = 384 cm²

Therefore, the area of the figure is 384 cm²

The area of the figure is ___<br> square units.
Zinaida [17]
Total area = area of the rectangle + area of the triangle

               = 3*2 + 2 * (1/2)2 

               = 6 + 2

               = 8 sq units.

Note the area of a triangle = 1/2 * base * height  Here the height = 2 and base = 2 units.
