If a=4,to find the value,we put a into the equation hence getting:

12-(4)/4
=12-1
=11
thus the value is 11

hope it helps!

Since “a” is equal to “4”, replace “a” in the equation with “4”.
12-4/4
Then, do PEMDAS. 4/4=1
12-1=11

The value of the equation is 11.

Rearrange 2y+6x=8 to make y the subject of the formula
Tomtit [17]

Answer:

y= 3x+4

Step-by-step explanation:

2y-6x=8

add 6x to each side

2y-6x+6x=6x+8

2y= 6x+8

divide each side by 2

2y/2 = 6x/2 + 8/2

y= 3x+4

The body weight of a healthy 3 month-old colt should be about μ = 60 kg. (Source: The Merck Veterinary Manual, a standard refere
tatuchka [14]

Answer:

a

  The null hypothesis will be  H_o : \mu = 60 \ kg

b

  The alternative hypothesis will be  H_a : \mu <  60

c

  The alternative hypothesis will be  H_a : \mu >  60

d

  The alternative hypothesis will be  H_a : \mu \ne   60

e

  left; right; both

Step-by-step explanation:

Considering question a

    The body weight of the colt is  \mu = 60 \ kg

    The null hypothesis will be  H_o : \mu = 60 \ kg

Considering question b

    Given that we want to test the claim that the average weight of a wild Nevada colt is less than 60 kg , then

The alternative hypothesis will be  H_a : \mu <  60

Considering question c

       Given that we want to test the claim that the average weight of such a wild colt is greater than 60 kg , then

The alternative hypothesis will be  H_a : \mu >  60

Considering question d

   Given that we want to test the claim that the average weight of such a wild colt is different from 60 kg , then

The alternative hypothesis will be  H_a : \mu \ne   60

Considering question e

   For question b  , the corresponding p-value will be on the left because the average weight is less than 60 kg

   For question c  , the corresponding p-value will be on the right  because the average weight is more than 60 kg

   For question d  , the corresponding p-value will be on both  because the average weight is different from  60 kg

3/4(12x−8)+3=10−1/2(6x+2)
Aleonysh [2.5K]

Answer:

x=1

Step-by-step explanation:

\frac{3}{4}(12x-8)+3=10-\frac{1}{2}(6x+2)

(9x-6)+3=10-(3x+1)

9x-6+3=10-3x-1

9x-3=9-3x

9x=12-3x

12x=12

x=1

The following figure is a regular hexagon. What is the value of w?<br><br> ILL GIVE BRAINLIEST!!!!
earnstyle [38]
The sum of the interior angle of a polygon is 720°, thus the value of w will be obtain as follows:
size of each angle is
720/6=120°
thus
8w=120
solving for w we get'
(8w)/8=120/8
w=15°
