Solve the equation. Check your solution: 0.25(3 + a) = 0.5

Answers (1)

2020-12-25
\((0.25(3+a))/0.25=(0.5)/(0.25)\)
3+a=2
3+a-3=2-3
checking
0.25(3+a)=0.5
0.25(3+(-1))=0.5
0.25(2)=0.5
0.5=0.5
a=-1
0

Celine, Devon, and another friend want to purchase some snacks that cost a total of $7.50. They will share the cost of the snacks. Which of these statements is true?
A. An equation that can be used to find x, the amount of money each person will pay is x+3=7.5. The solution to the equation is 4.5, so each person will pay $4.50.
B. An equation that can be used to find x, the amount of money each person will pay is x+3=7.5. The solution to the equation is 10.5, so each person will pay $10.50.
C. An equation that can be used to find x, the amount of money each person will pay is x⋅3=7.5. The solution to the equation is 2.5, so each person will pay $2.50.
D. B. An equation that can be used to find x, the amount of money each person will pay is x⋅3=7.5. The solution to the equation is 22.5, so each person will pay $22.50.
