WHAT IS -45 - x = - 18
SHOW STEPS PLEASE ALSO FOR
v - 55 = -43
AND -2 = n/10

x = -27, v = 8, n = -20.

Step-by-step explanation:

-45 - x = -18

+45         +45

-x  =  27

/-1       /-1

x = -27

v - 55 = -43

+ 55       +55

v  = 12

-2 = n/10

*10    *10

-20 = n

x = -27

v = 12

n = -20

Step-by-step explanation:

1) -45 - x = - 18

- Add 45 to both sides

-45 - x + 45 = -18 + 45

Group like terms:

-x + -45 + 45 = -18 + 45

Simplify the arithmetic:

-x = -18 + 45

Simplify the arithmetic:

-x = 27

- Isolate the X

Multiply both sides by-1

-x · -1 = 27 · -1

Remove the one(s):

x= 27 · -1

Simplify the arithmetic:

x= -27

2) v - 55 = -43

1. Group all constants on the right side of the equation

v - 55 = -43

Add 55  to both sides:

v - 55 + 55 = -43 + 55

Simplify the arithmetic:

v = -43 + 55

Simplify the arithmetic:

v = 12

3)  -2 = n/10

1. Swap sides

-2 = n/10

Swap sides

n/10 = -2

2. Isolate the n

n/10 = -2

Multiply to both sides by 10:

n/10 * 10 = -2 * 10

Group like terms:

1/10 * 10n = -2 * 10

Simplify the fraction:

n = -2 * 10

Simplify the arithmetic:

n = -20  

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

8y^50
