What is 155.78=2.95h+73.18<br> a. 28<br> b. 36<br> c. 3.6<br> d. none of these
xz_007 [3.2K]

Answer:

a. 28

Step-by-step explanation:

Given:

155.78=2.95h+73.18

We need to evaluate given expression to find the value of 'h'.

Solution:

155.78=2.95h+73.18

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

155.78-73.18=2.95h+73.18-73.18\\\\82.6=2.95h

Now we will use Division property of equality and divide both side by 2.95 we get;

\frac{82.6}{2.95}=\frac{2.95h}{2.95}\\\\h=28

Hence After evaluating given expression we get the value of 'h' as 28.
