The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?

valentina_108 [34]

Answer:

a=1/2

Step-by-step explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

$a(8x+7)\equiv 4x+3.5$

we can write the following

8ax=4x

$\implies a=\frac{4x}{8x}= \frac{1}{2}$

Hence the value of a is 1/2
