R + 3 1/2 = -4 2/3

alexandr402 [8]

Answer:

R = -8 1/6

Step-by-step explanation:

We'll solve the given equation for R.

Subtract 3 1/2 from both sides of the equation, to isolate R:

R + 3 1/2 - 3 1/2 = -4 2/3 - 3 1/2, or

R = -4 2/3 - 3 1/2

The LCD here is 6, which is the product of 3 and 2. Converting the fractions to denominator 6, we get:

R = -4 4/6 - 3 3/6, or

R = -7 - 7/6, or R = -7 - 1 1/6, or -8 1/6

Answer:

$x =320$

Step-by-step explanation:

Given

$x^2 + 200x = 166400$

Required

Find x

We have:

$x^2 + 200x = 166400$

Rewrite as:

$x^2 + 200x - 166400 = 0$

Expand

$x^2 + 520x - 320x - 166400 = 0$

Factorize

$x(x + 520) - 320(x + 520)= 0$

Factor out x + 520

$(x - 320) (x + 520)= 0$

Split

$x - 320 = 0\ or\ x + 520= 0$

Solve

$x = 320\ or\ x =- 520$

Side length must be positive;

So:

$x = 320$
