Answer:
£22.40
Step-by-step explanation:
60% of 12 is 7.2 (you can also write it as 7.20) so you times that by 2 to get 14.4 (you can also write it as 14.40) and 
of 24 is 8, so you add that to the 14.4 and you get 22.4 (also writen as 22.4) hope this helps!
F^-1(x) = -4 + 2x
Interchange the variables, then solve for y.
Answer: A) (2+2) x 3
Step-by-step explanation: The answer to the problem (2 X 3) + (2 X 3) is 12 so we have to find the eqaution in the answers that equals 12,
B) 2 + (3+3) is equal to 8 so that can't be the correct answer
C) 2 x 3 x 3 is equal to 18 so that can't be the correct answer
D) (2 + 3) x (3+2) simplifies to 5 x 5 which is 25 so that can't be the correct answer
So that leaves us with A) (2+2) x 3 as the correct answer because it equals <u>12</u>
Answer:
x = - 4
Step-by-step explanation:
Given
x + 4 = 
x
Multiply through by 3 to clear the fractions
5x + 12 = 2x ( subtract 2x from both sides )
3x + 12 = 0 ( subtract 12 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
