<span>-5x-10=10
Add 10 to both sides
-5x= 20
Divide both sides by -5 so that the only thing remaining on the left side is the variable x.

One number exceeds another by 18 and their sum is 36.
AnnZ [28]

x - first number

x + 18 - second number

x + (x + 18) = 36

x + x + 18 = 36

2x + 18 = 36        | - 18

2x = 18           | : 2

x = 9

First number: x = 9

Second number: x + 18 = 9 + 18 = 27

Those numbers are 9 and 27.

A circular path 4 feet wide has an inner diameter of 550 feet. How much farther is it around the outer edge of the path than aro
Softa [21]

Answer:

L_c=25.12ft

Step-by-step explanation:

From the question we are told that

Width of circular path w_c=4ft

Inner Diameter d_i_n=550ft

Outer diameter d_{out}= 550 +2*4  (inner diameter +  2 circular path width)

d_{out}= 550 +8\\d_{out}= 558ft

Generally the equation for inner circumference of the circle C_1 is mathematically given by

C_1=\pi d_{in}

C_1=3.14*550

C_1=1727ft

Generally the equation for outer circumference of the circle C_2 is mathematically given by

C_2=\pi d_{out}

C_2=3.14*558

C_2=1752.12ft

Generally the difference in length of the two circumference L_c is mathematically given by

L_c=C_2-C_1

L_c=1752.12-1727

L_c=25.12ft
