C = 5/9(F - 32)...multiply both sides by 9/5, eliminating the 5/9 on the right
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F <===
Ok................? is there more to this
Step-by-step explanation:
An inequality does not use the equal sign (=). Instead, it uses >, ≥, <, or ≤ signs.
The answer is option D.
7 1/2 = 7.5
multiply this by 100 to get per cent:-
7.5 * 100 = 750 %
Answer:
DF = 57
Step-by-step explanation:
From the given information on the line segments we can write the equation
DF = DE + EF ( substituting the values into the equation )
9x - 15 = 4x + 10 + 2x - 1
9x - 15 = 6x + 9 ( subtract 6x from both sides )
3x - 15 = 9 ( add 15 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
DF = 9x - 15 = (9 × 8) - 15 = 72 - 15 = 57
