Given:

At a college, the tuition increased by 10%. Let b be the former cost of tuition.

Use the expression b + 0.10b for the new cost of tuition.

To find:

The equivalent expression by combining like terms.

Solution:

We have,

b + 0.10b

On combining the like terms, we get

b + 0.10b=1.10b

Therefore, the required equivalent expression is 1.10b.

<h3><u>Answer:</u></h3>

\boxed{\boxed{\pink{\bf The \ two \ numbers \ are \ 12  \& \ 85 . }}}

<h3><u>Step-by-step explanation:</u></h3>

Given that , One number is 1 more than 7 times the other number. If their sum is 73 more than

twice the smaller number. And we need to find the numbers. So let us take the

  • First Number be x .
  • Second number be 7x+1 .

\underline{\red{\boldsymbol{ According \ to \ the \ Question :- }}}

\bf\implies 2( Small \ no.) + 73 = Bigger \ no. + Smaller \ no.\\\\\bf\implies 2x + 73 = x + 7x + 1\\\\\bf\implies 2x + 73 = 8x + 1 \\\\\bf\implies 8x - 2x = 73-1 \\\\\bf\implies 6x = 72 \\\\\bf\implies x =\dfrac{72}{6}  \\\\\bf\implies \boxed{\red{\bf x = 12 }}

Hence the smaller number is 12 and the bigger number will be :-

\bf \implies Number_{bigger} = 7x + 1 \\\\\bf\implies Number_{bigger} =7(12)+1\\\\\bf\implies Number_{bigger} = 84 + 1 \\\\\bf\implies \boxed{\red{\bf Number_{bigger}=85 }}

<h3><u>Hence </u><u>the</u><u> </u><u>bigger </u><u>number</u><u> </u><u>is</u><u> </u><u>8</u><u>5</u><u> </u><u>and</u><u> </u><u>the </u><u>small</u><u>er</u><u> number</u><u> </u><u>is</u><u> </u><u>1</u><u>2</u><u>. </u></h3>
