Step-by-step explanation:
question number 2 first part X + 2 is equal to 7 .. x is equal to 7 - 2x is equal to 5 ..second part 3 x minus 1 is equal to 3 x is equal to 23 - 1 = 3x=24 x=24÷3=x=8ans
Answer:
last option
Step-by-step explanation:
b) 1/6 = 16.7 to 1dp
c) 45% = 45/100 = 9/20
d) 7/9 = 77.8% to 1dp
We have ( 5x+16 + 8x + 4 - 4x -2 )/3 = (9x + 18) / 3 = 9( x + 2 ) / 3 = 3( x + 2 ) = 3x + 6;
