Answer:
The smallest possible value for x is 6
Step-by-step explanation:
3(x + 3) ≤ 5x - 3
Distribute the 3
3x+9 ≤ 5x - 3
Subtract 3x from each side
3x+9-3x ≤ 5x-3x - 3
9 ≤ 2x - 3
Add 3 to each side
9+3≤ 2x - 3+3
12 ≤ 2x
Divide by 2
12/2≤ 2x /2
6 ≤ x
The smallest possible value for x is 6
Answer:
25 and
9
Step-by-step explanation:
Let the number of males be A and that of females be B
Total number of students = 34
Number of females B = A - 16
Remember males and females = 34
That’s
A + B = 34
We now have two equations
Equation one:B = A - 16
Equation two: A + B = 34
Substitute A - 16 for B in equation 2
We have,
A + B = 34
A + A - 16 = 34
2A - 16 = 34
Add 16 to both sides
2A - 16 + 16 = 34 + 16
2A = 50
Divide both sides by 2
2A/2 = 50/2
A = 25
Now put 25 as A in any of the equations to get B
Using equation one , we have
B = A - 16
B = 25 - 16
B = 9
There are 25 males and 9 females in the class
