1.4375

<u>Step-by-step explanation:</u>

Step 1:

Let the given equation be     1+12(4X-6)=-2

To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.

Step 2:

Let us expand the equation as 1+ (12*4X)-(12*6)=-2

Step 3:

Let us expand it further as 1+48X-72=-2

Step 4:

To find X segregate X in one side and all other remaining terms in other side as follows

48X=-2+72-1

After the simplification the numerical value is

48X=69

Step 5:

Keep X along one side and bring 48 to the denominator of another side to find X as follows

X=69/48

And the value of X is 1.4375

Answer:

x = 1 7/16

Step-by-step explanation:

1 + 1 2 ⋅ (4x − 6) = −2

Subtract 1 from each side

1-1 + 1 2 ⋅ (4x − 6) = −2-1

1 2 ⋅ (4x − 6) = −3

Distribute the 12

48x -72 = -3

Add 72 to each side

48x-72+72 = -3+72

48x =69

Divide by 48

48x/48 = 69/48

x =1 21/48

x = 1 7/16

The two-digit number you are looking for is 12. 

4 x 3 = 12. 

6 x 2 = 12. 

This fits your criteria.

Y varies directly as x squared. y is 18 when x is 3. Find y if x is 4. Any help? thanks ​
stealth61 [152]

Answer:

Step-by-step explanation:

y ∝ x^2

Introducing the proportionality constant, we have  

y = kx^2

Given : y= 18 when x = 3

substitute the given values in order to get the constant

i.e 18 = k x 3^2

     18 = 9k

      k = 2

therefore the formula connecting  x and y

⇒ y = 2x^2

To find y if x is 4, just substitute x = 4 into the formula connecting x and y

i.e y = 2 x 4^2

       = 2 x 16

       = 32

(1 point) 1. The height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees are measured by a researcher. T
Thepotemich [5.8K]

Answer:

C. volume

Step-by-step explanation:

The response variable in this scenario would be the volume of the usable lumber. That is because this variable depends completely on the height of the cherry trees that are being measured. The higher that the cherry trees are the more volume can be expected to get from cutting these trees down. The opposite goes for trees that are smaller, they would decrease the total expected volume that will be received from the usable lumber since there would be less amount of tree to cut down.
