Let "x" be a substitute for "a number"
1/3(x)=x-12 Multiply by 3
x=3x-36 Get n onto the same side of the equation
2x=36 Divide by 2
x=18
That's your answer.
Answer: 47 students
Step-by-step explanation:
430 students went on a trip with the majority of them going on buses.
7 students however, had to use cars.
The number of students who used buses are:
= 430 - 7
= 423 students
The number of students in each bus is:
= No. of students taking buses / no. of buses
= 423 / 9 buses
= 47 students
1. 56 : 35 = 1.6
2. 1.6* 100 = 160
3. The answer is 160
The inverse of this function is not a function and this function isn’t inversable because it’s not one to one
16 +28+32+4=80 80 total coins x.15 =12 coins sold
