Translating this sentence into symbols: 2(x+3) = x - 5

So 2x + 6 = x - 5 and x = -11

Check: Is 2(-11+3) = -11 -5? Is -16 = -16? YES. x =-11 is right.

1. Here is a circle. Points A, B, C, and D are drawn, as

Darya [45]

The area of the circle is approximately 50

<h3>Areas</h3>

The area of a shape is the amount of space occupied by the shape

<h3>Area of circle</h3>

Given the three radius of the circle, the area of the triangle is calculated using:

$Area = \pi r^2$

From the figure, we have:

$AD = 4$ --- the radius

So, we have:

$Area = \pi r^2$

$Area = 3.14 \times 4^2$

$Area = 50.24$

Approximate

$Area = 50$

Hence, the area of the circle is approximately 50

Which equation represents this situation?

aalyn [17]

Answer:

dirk =13.25 hours

charlie =11 75 hours

Step-by-step explanation:

c+d=25------(1)

d-1.5=c-----(2)

from (1),

c+d=25

c=25-d-----(3)

substitude (3) into (2)

d-1.5=c

d-1.5=25-d

2d=26.5

d=13.25

if d=13.25 hours

c+d=25

c+13.25=25

c=25-13.25

c=11.75
