-6(2+a)=-48 what is the value for a
1 answer:
Answer:
The answer should have positive sign.
Step-by-step explanation:
First you do is divide by -6 from both sides of an equation.
Then, simplify and solve the problem.
Next, you switch sides.
You subtract by 2 from both sides of an equation./
Finally, solve/simplify.
A=6 is the correct answer.
Hope this helps you!
Have a nice day! :)

Let's recall that in a parallelogram:
1. The opposite sides are paralell
In our exercise. sides CZ and KG are paralell. And so do sides KC and GZ.
2. Those opposite sides are equal in length.
3. The opposites angles are equal. In our exercise, angle C and G are equal and so do angles K and Z.
4. That also mean that the angles at the top of the figure are supplementary. It means they add up to 180 degrees. We have the same situation with the two angles at the bottom of the parallelogram.
In our case then:
Now, we can find the measure of angles K and Z, as follows:
Answer:
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
When y = 1, x = 2;
So, we have:
Make k the subject
Hence, the constant of proportionality is 1/2
