Which is the solution to the equation 2.6a + 18.4 = 28.8 round the nearest tenth if necessary. 1.4, 4, 18.2, 27,
Answer:
The solution is 4.
Step-by-step explanation:
Given expression is,
\(2.6a+18.4=28.8\)
Subtracting 18.4 on both sides,
\(2.6a+18.4-18.4=28.8-18.4\)
\(2.6a=10.4\)
Dividing 2.6 on both sides,
\(a=\frac{10.4}{2.6}=4\)
Since for a = 4,
\(2.6a+18.4=28.8\) is satisfied.
Hence, the solution of the given expression is 4.
