W = women
m = men
w = 3m (from the first sentence)
1/3w - 3/5m = 120
subsitute 3m for w
1/3(3m) - 3/5m = 120
m - 3/5m = 120
2/5m = 120
2m = 600
m = 300
back to the original equation
w = 3m
w = 3(300)
w = 900
900 women + 300 men = 1200 people.
Answer:
- 3x + 4 = 9x -6
- 3x + 4 = 3x + 5
- 9x + 6 = 9x + 6
Step-by-step explanation:
Let x is the variable in each type of equation
1/ an equation that has one solution:
3x + 4 = 9x -6
<=> 9x - 3x = 4+6
<=> 6x = 10
<=> x =
2/ an equation that has no solution:
3x + 4 = 3x + 5
<=> 3x - 3x = 5-4
<=> 0 = 1 impossible
3/ an equation that has infinite many solutions:
9x + 6 = 9x + 6
<=> 9x - 9x = 6 -6
<=> 0 = 0 (obvious) no matter what we put in for x
Hope it will find you well.
Answer:
C=25.13cm
Step-by-step explanation:
A=50.24
A=πr^2
C=2πr
