(b) 10p + 10 = 100 (c)
4
Please solve this fast. It's urgent​

Answer 1

Answer:

10p=100

p=100/10

p=10

10p+10=100

10p=90

p=9

Answer 2

(a) We have

10p = 100

$\sf \implies \: \: \: \: \: \: \: \: \frac{10p}{10} = \frac{100}{10} \: \: \bigg[dividing \: \: both \: \: sides \: \: by \: \: 10 \bigg]</p><p>$

$\sf \implies \: \: \: \: \: \: \: \: p = 10$

So, p = 10 is solution of the given equation.

(b) We have

10p + 10 = 100

$\sf \implies \: \: \: \: \: \: \: \: 10p + 10 - 10 = 100 - 10 \sf \bigg[subtract \: \: 10 \: \: from \: \: both \: \: sides \bigg]$

$\sf \implies \: \: \: \: \: \: \: \: 10p = 90$

$\sf \implies \: \: \: \: \: \: \: \: \frac{10p}{10} = \frac{90}{10} \: \: [dividing \: \: both \: \:sides \: \: by \: \: 10 ]$

$\sf \implies \: \: \: \: \: \: \: \: p = 9$

So, p = 9 is the solution of the Given equation.

(c) we have,

$\sf \frac{p}{4} = 5$

$\sf \implies \: \: \: \: \: \: \: \: \frac{p}{4} \times 4 = 5 \times 4 \bigg[ multiplying \: \: both \: \: sides \: \: by \: \: 4\bigg] </p><p>$

$\\ \sf \implies \: \: \: \: \: \: \: \: p = 20$

so, p = 20 is the solution of the given equation
