A horseshoe weighs 8.2 ounces. The nails make up 0.2 of that weight. What is the weight of the horseshoe without the nails?

Answers

Answer 1

Answer: 8.2=82/10

0.2=1/5

---------------------

1/5*82/10=82/50

---------------------

82/10-82/50

=820/100-164/100

=656/100

=6.56

Answer: 6.56 ounces

Answer 2

Answer: 8.2 Ounces because it says a HORSESHOE Weighs. They threw in the nails weight to throw you off.

What are the solutions to the equation (x – 6)(x + 8) = 0?x = –6 or x = 8
x = –6 or x = –8
x = 6 or x = –8
x = 6 or x = 8

Answers

x=6 and x=-8

To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.

Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
