Answer:

[tex]a = 10[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{5} = \frac{a + 5}{25}[/tex]

Required

Find a

[tex]\frac{3}{5} = \frac{a + 5}{25}[/tex]

Multiply both sides of the equation by 25

[tex]25 * \frac{3}{5} = \frac{a + 5}{25} * 25[/tex]

[tex]5 * 3 = a + 5[/tex]

[tex]15 = a + 5[/tex]

Subtract 5 from both sides

[tex]15 - 5 = a + 5 - 5[/tex]

[tex]10 = a[/tex]

[tex]a = 10[/tex]
