Answer:

x = -3

Step-by-step explanation:

y = -x + 2

7x + 4y = -1

Subsitution method: (Substitute y)

7x + 4(-x+2) = -1

Expand.

7x + (-4x + 8) = -1

One plus and one minus make one minus. Two plus makes a plus.

7x -4x + 8 = -1

Simplify.

3x + 8 = -1

Isolate 3x.

3x = -1-8

= -9

Find x.

x = -9 ÷ 3

= -3

If an exterior angle of a regular polygon is 21.2Â°, how many sides does the polygon have?

sesenic [268]

360 divided by x = 21.2 recurring
So rearrange that to get x = 360 divided by 21.2
Which rounds up to 17

Answer and Step-by-step explanation:

$Hello!~$

$Let's~answer~your~question!$

$So,~for~this~equation,~we~need~to~use$ $~the~distributive~property~of$ $~multiplication.~but,before~we~start~to~solve$ $this~equation,~let's~get~to~know~what$

$distributive ~property ~of~multiplication~means!$

Distributive property of multiplication :

$Distributive~property~of~multiplication~states~that$ $when~a~~number~is~multiplied$

$by~the ~sum ~of~ two~ numbers,$ $the~ first~ number ~can~ be ~distributed ~to$ $both ~of~those$ $numbers~and~multiplied~by~each~of~them$ $separately.$

→ $a*(b+c)=a*b*+~a*c$

Now, that we know what it means let's apply it in our equation:

 $(2*x)+(2*7)=36$ 

Now, we simplify:

 $2x+14=36$ 

Divide both sides by 2 in the equation:

 $\frac{2x+14}{2} =\frac{36}{2}$ 

Simplify :

 $x+7=18$ 

Thus, the first correct step is option B,

 $then~comes,~option~"A"~then,~option~"F"~as~shown~above$ $The~remaining~options~are~not~enough~information~to~solve~the~given$ $equation:(x + 7) = 36.$
