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>

Solve the logarithmic equation with Properties of Logs
Rufina [12.5K]

Answer:

Simplifying

logx + -4 = 0

Reorder the terms:

-4 + glox = 0

Solving

-4 + glox = 0

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + glox = 0 + 4

Combine like terms: -4 + 4 = 0

0 + glox = 0 + 4

glox = 0 + 4

Combine like terms: 0 + 4 = 4

glox = 4

Divide each side by 'lox'.

g = 4l-1o-1x-1

Simplifying

g = 4l-1o-1x-1

Multi step equation 12 threw 14 pls
slega [8]

The computation of the equation shows that the answers will be:

12. 340 units

13. 2(270) + (2 × x) = 690

14. x = 5

<h3>How to compute the equations?</h3>

12. The first equation that's given will be:

(13.50 × x) - (3.65 × x) = 3349

13.50x - 3.65x = 3349

9.85x = 3349

x = 3349/9.85

x = 340

The number to break even is 340 units

13. The equation that can be used to find the perimeter will be:

2(270) + (2 × x) = 690

540 + 2x = 690

2x = 690 - 540

2x = 150

x = 150/2 = 75

14. x + x + 2 + 8 = 20

2x + 10 = 20

2x = 20 - 10

2x = 10

x = 10/2

x = 5
