4(2x + 3) ÷ 5y
ololo11 [35]

Step-by-step explanation:

We do the brackets first, following BODMAS rules

so, 4× 5x ÷ 5y = 1xy.

= 4 × 1xy

= 4xy.

I guess that's the answer.

Example Of:-

<u>Sum:</u>

<em>2</em><em>x</em><em> </em><em>+</em><em> </em><em>7</em><em>y</em>

<u>term:</u><u> </u>

<em>5x + 7 = 5x and 7 are terms. </em>

<u>product</u><u>:</u>

<em>2a × 3b </em>

<u>factor:</u><u> </u>

<em>always </em><em>remember</em><em>,</em><em> </em><em>a </em><em>number </em><em>is </em><em>a </em><em>factor </em><em>of </em><em>itself.</em>

<em>5</em><em>x</em><em> </em><em>+</em><em> </em><em>7</em><em>y</em>

<em>factors </em><em>=</em><em> </em><em> </em><em>5</em><em> </em><em>+</em><em> </em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em>x</em><em> </em><em>+</em><em> </em><em>7</em><em> </em><em>+</em><em> </em><em>y </em><em>+</em><em> </em><em>7</em><em>y</em><em>.</em>

<u>Quotient:</u><u> </u>

<em> </em><em>1</em><em>0</em><em>d</em><em> </em><em>÷</em><em> </em><em>5</em><em>j</em><em> </em><em>=</em><em> </em><em>2</em><em>d</em><em>j</em><em> </em>

<u>coefficient</u><u>:</u><u> </u>

<em>In the number 3x, </em><em>3</em><em> </em><em>is </em><em>the </em><em>coefficient</em><em> </em><em>of </em><em>x.</em><em> </em>

<em>but,</em><em> </em><em>in </em><em>the </em><em>number </em><em>x </em><em>(</em><em>raise </em><em>to)</em><em> </em><em>2</em><em>,</em><em> </em><em>the </em><em>coefficient</em><em> </em><em>is </em><em>1</em><em>.</em><em> </em>

<em>hope \: it \: helps \: you</em>
