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>

Help me …… please ! I Just need help
frozen [14]

Answer:

(2,-2)

Step-by-step explanation:

y=-4x+6

y=3x-8

plug the y's in for each other to get:

-4x+6=3x-8   <----- solve from there

+8            +8

-4x+14=3x

+4x         +4x

14=7x

/7     /7

x=2

now plug the x in to get y (in any problem)

y=3(2)-8

y=6-8

y=-2

In the diagram below, TUVW is a rectangle. Prove triangle TZW is congruent to triangle UZV.
otez555 [7]

Answer:

By S.S.S. congruence property;  ΔTZW ≅ ΔVZU

Step-by-step explanation:

Given:

TUVW is a rectangle.

To Prove : TZW ≅ UZV

Proof:

Since TUVW is a rectangle, and we know that opposite side of a rectangle is equal.

So,

TW = UV \ \ .\ .\ .\ .\ 1

And also TV and WU are the diagonals of the rectangle.

And the diagonals of rectangle bisects each other.

Therefore;

TZ=ZV.........\ 2\\\\WZ=ZU..........\ 3

Now In ΔTZW and ΔVZU

TW = UV (from 1)

TZ = ZV (from 2)

WZ = ZU (from 3)

So, by S.S.S. congruence property;

ΔTZW ≅ ΔVZU

Hence proved.
