Answer:

[tex]52\frac{5}{8}[/tex] inches

Step-by-step explanation:

We are given that brad grew [tex]4\frac{1}{4}[/tex] inches this year and now height of brad is [tex]56\frac{7}{8}[/tex] inches

We have to write an equation for finding of height of Brad and find the height of brad at the start of this year.

Let x be the height of Brad at the start of this year

According to question

[tex]x+4\frac{1}{4}=56\frac{7}{8}[/tex]

[tex]x+\frac{17}{4}=56 \frac{7}{8}[/tex]

[tex]x=\frac{455}{8}-\frac{17}{4}[/tex]

[tex]x=\frac{455-34}{8}[/tex]

[tex]x=\frac{421}{8}[/tex]

[tex]x=52\frac{5}{8}[/tex]

Hence, the height of brad at this year =[tex]52\frac{5}{8}[/tex] inches
