Answer:
The correct answer is a = 16.
Step-by-step explanation:
Step 1: Subtract 0.5 from both sides.
0.25a + 0.5 − 0.5 = 4.5 − 0.5
0.25a = 4
Step 2: Divide both sides by 0.25.
0.25a/0.25 = 4/0.25
a = 16

Answer: 16
Step-by-step explanation:
0.25a+0.5=4.5
Collect like terms
0.25a=4.5-0.5
0.25a=4
Convert 0.25 to fraction
That gives 25/100
25/100=1/4
So we have
1/4×a=4
Cross multiply
a= 4×4
a=16
