Well this does take some work on scratch paper but ill let you know that we have to plug these in to make one whole big equation
lets do that!
x + 5 = -5x - 1 now add +1 to both sides of the equation
+ 1 = +1 it cancels out on the right side and we solve on the left
*****************
x + 6 = -5x Now lets subtract that(1x) from both sides
-1x = -1x ( if x stands alone, theres always an imaginary 1 right by it)
************** now -5 - 1 = -6 so its -6x
6 = -6x Now divide both sides by -6 to isolate x to be alone
÷-6 = ÷6 It cancels out on the right side and we solve on the left
************ 6 ÷ -6 = 0 so lets see what we have
0 = x
Since zero is still a number this means there is only 1 solution!
Answer = A.) one
I hope this helps!
and dont forget 2

Simple...
you have:
![\frac{z}{12} =9](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz%7D%7B12%7D%20%3D9)
To solve this..you want to isolate the variable (z)...
1.) Cancel out the 12 by multiplying it out--->>>>
![12* \frac{z}{12} =9*12](https://tex.z-dn.net/?f=12%2A%20%5Cfrac%7Bz%7D%7B12%7D%20%3D9%2A12)
Leaving you with....
z=108
Then-->>>
5*g=230
Again, isolate the variable....
1.) Do this by dividing both sides by 5.....
5*g=230
![\frac{5*g}{5} = \frac{230}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%2Ag%7D%7B5%7D%20%3D%20%5Cfrac%7B230%7D%7B5%7D%20)
g=46
Thus, your answer.
Answer:140
Step-by-step explanation: 7x+4=13x-8 SOLVE FOR X, x=2, SOLVE EACH SIDE, JH=18, HK=18, KI=IL, GL=GJ, JH=HK, SO LI IS 15 SINCE KI IS 15, 52-15=37, LG=37, GJ=37. 18+18+15+15+37+37=140
Answer:
let's divide the figure into two parts.
radius of the semicircle is 3.5m. two semi-circles make a circle and
area of circle=pi×r²
area of circle=22/7×(3.5m)2².
area of circle=38.5m²
area of rectangle=length ×width
area of rectangle =18m×7m
area of rectangle =126m²
area pf figure =38.5m²+126m²
area of figure=164.5m²
