Answer :
The equations that have a solution of c=1.5 are 4c=41.5 and 0.2c=0.3.
1. 4c=41.5:
To find the value of c, divide both sides of the equation by 4:
4c/4 = 41.5/4
c = 10.375
Since c is not equal to 1.5, this equation does not have a solution of c=1.5.
2. 150c=100:
Divide both sides of the equation by 150:
150c/150 = 100/150
c = 0.6667
Since c is not equal to 1.5, this equation does not have a solution of c=1.5.
3. 13.5-c=10:
Subtract 10 from both sides of the equation:
13.5 - 10 - c
3.5 - c
Rearrange the equation to isolate c:
-c = -3.5
Divide both sides by -1 (or multiply by -1):
c = 3.5
Since c is not equal to 1.5, this equation does not have a solution of c=1.5.
4. 6c=9:
Divide both sides of the equation by 6:
6c/6 = 9/6
c = 1.5
This equation has a solution of c=1.5.
5. 0.2c=0.3:
Divide both sides of the equation by 0.2:
0.2c/0.2 = 0.3/0.2
c = 1.5
This equation has a solution of c=1.5.
