Statements are all TRUE
sinA =
and cosB = 
cscA = 1/sinA = 1/(a/c) =
and secB = 1/cosB = 1/(a/c) = 
tanA =
and cotB= 1/tanB = 1/ (b/a) = 
C = 5/9(F - 32)....multiply both sides by 9/5
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F
700 times 3 is 2,100, You get 700 from estimating 697
Answer:
C and D
Step-by-step explanation:
You can tell if equations have no solution if the variables on both sides of the equation are the same.
Choice C is 10+6x=15+9x-3x. You would combine 9x and -3x, turning the equation into 10+6x=15+6x. Since there is a 6x on both sides, Choice C would have no solution.
The same for Choice D. When you simplify everything there is a 3x on both sides, so it would have no solution.
