Answer:
D. a = 3 1/2
Step-by-step explanation:
Plug in values
10 = 2a +3
Subtract 3 from both sides
7 = 2a
Divide both sides by 2
3 1/2 = a
Answer: [tex]3\frac{1}{2}[/tex]
Step-by-step explanation:
Here the given expression,
2a + b = p
By putting p = 10 and b = 3 in the above expression,
We get,
[tex]2a + 3 = 10[/tex]
[tex]\implies 2a = 10 - 3[/tex]
[tex]\implies 2a = 7[/tex]
[tex]\implies a = \frac{7}{2} = 3\frac{1}{2}[/tex]
Hence, Option C is correct.
