Which equation is related to the given equation? column a column b 1. 61 + 18 = z 2. z = 61 – 18 3. –18 = 61 – z 4. 18 = 61 – z
Fofino [41]

Question 1.).

Column A.):  

Answer ==>  z  =  61  –   18, is Related to  z  +  18   =  61,   ==>   z    =   43

Answer: ===>  18   =    61    -  z,  is Related to  z    +   18   =  61,   ===>   z   =   43

z      +     18     =   61

Let's solve your equation step-by-step.

z     +     18      =     61

Step 1: Subtract 18 from both sides.

z  +   18   −   18    =     61    −     18

z     =     43

Graph:  ========>   z    +    18     =     61  =========>     z     =======>    43

Column (A),     Answer:     =======>     z     =      43



Question 2.).  

Column. B.):  

Answer: =====>   61 + 18   =   z,  Related to z  - 18  =  61  ====>  z   =   79 Answer: ===>   –18   =   61   –   z,  Related to   z  -   18   =  61  ====>  z  =  79    

z      -     18     =     61

Let's solve your equation step-by-step.

z         −       18        =           61

Step 1: Add 18 to both sides.

z     −     18     +     18     =     61       +        18

z    =       79

   Answer     z     =      79




Therefore, The answers to your Equation: Column (A),/Column (B)

Question 1.).

Column A.):  

Answer ==>  z  =  61  –   18, is Related to  z  +  18   =  61,   ==>   z    =   43

Answer: ===>  18   =    61    -  z,  is Related to  z    +   18   =  61,   ===>   z   =   43



Question 2.).  

Column. B.):  

Answer: =====>   61 + 18   =   z,  Related to z  - 18  =  61  ====>  z   =   79 Answer: ===>   –18   =   61   –   z,  Related to   z  -   18   =  61  ====>  z  =  79  





Hope that helps!!!!!!!!                            : )

△ABC is a 30-60-90 triangle where m∠B=90° . The length of the shorter leg is 11 units.
tatyana61 [14]
Start with where the shorter leg is. It must be opposite the smallest angle.

In a 30 - 60 - 90 degree triangle you have the hypotenuse to be twice as long as the shortest side. You have to read that a couple of times to make sure you understand it. 

That being said, if the shortest side is x, the hypotenuse will be 2x.

Since in this case the shortest side is 11, the hypotenuse will be 2*11 = 22

-2 - 6
Tatiana [17]

Answer:

-8

4

-15

-8

7

42

-60

15

-9

-12

Step-by-step explanation:

-2 - 6 = -8

8 + (-4) = 4

10 + (-25) = -15

-15 - (-7) = -8

-6 - (-13) = 7

-7 x -6 = 42

-12 x 5 = -60

60/4 = 15

72/-8 = -9

48/-4 = -12
