It should be 0.0849 because when you do this your just moving the decimal place two time
First the equation would look like this:
7n = 5n - 3
7n - 5n = 5n - 5n - 3 -Subtract 5n from both sides. Which gives you...
2n = -3
2n/2 = -3/2 -Divide both sides by 2
n = -1.5
Hope this helps!
Given that angle ABC is congruent to angle DEF and angle GHI is congruent to angle DEF, angle ABC is congruent to angle GHI by the Transitive Property of Equality. The Transitive Property of Equality states that if a = b and b = c, then a = c.
Isolate for s?
1/2s + 21 = 4s-21 +21
1/2s+ 21 =4s
1/2s + 21- 1/2s = 4s - 1/2
21 = 3.5 s
21/3.5 = 3.5s/3.5
6= s
