How do you solve #0.2( 2x + \frac { 1} { 2} ) = 510.5+ ( - 2) 1#?

Answer 1

Eva Adamson

#x=1271#

#0.2(2x+1/2)=510.5+(-2)1#

Expand the brackets #0.4x+0.1=510.5-2#

Make #0.4x# your subject #0.4x=510.5-2-0.1#

Simplify #0.4x=508.4#

Divide both sides by #0.4# #x=1271#

To solve the equation 0.2(2x + 1/2) = 510.5 - 2(1), first distribute 0.2 on the left side: 0.4x + 0.1 = 510.5 - 2. Then, combine like terms: 0.4x + 0.1 = 508.5. Next, subtract 0.1 from both sides to isolate the variable term: 0.4x = 508.4. Finally, divide both sides by 0.4 to solve for x: x = 1271.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
