81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
5x-3=42. To solve you add three to both sides making the equation 5x=45. Then you divide both sides by five, and you get 9 as your answer.
Complementary angles add up to 90 degrees.
The complement of 57 is (90 - 57) = 33 degrees.
Answer:
c=38
Step-by-step explanation:
Substitute 6 for r and -2 for t in the formula given
c=rt^(2)-3t+8
c=6*(-2)^2-3*(-2)+8
c=6*4-3*-2+8
c=24+6+8
If a, b and c are the lengths of the sides of a triangle then
if a ≤ b ≤ c, then a + b > c.
A: 4, 12, 15
4 + 12 = 16 > 15 CORRECT :)
B: 4, 13, 15
4 + 13 = 17 > 15 CORRECT :)
C: 4, 4, 15
4 + 4 = 8 < 15 INCORRECT :(
D: 4, 15, 15
4 + 15 = 19 > 15 CORRECT :)
E: 4, 11, 15
4 + 11 = 15 INCORRECT :(
F: 4, 15, 19
4 + 15 = 19 INCORRECT :(
<h3>Answer: A: 12, B: 13, D; 15</h3>
