Answer:
You could by 8 magazines
Step-by-step explanation:
First, set up the equation 6/12=x/16
cross multiple to get 12x=96
divide both sides by 12 and x = 8
The measurement of angles are :
- Angle 1 is 123°
- Angle 2 is 57°
- Angle 4 is 123°
- Angle 5 is 123°
- Angle 6 is 57°
- Angle 7 is 57°
- Angle 8 is 123°
Given,
The figure with parallel lines.
Angle 3 is given as 57°
We have to find the other angles.
∠1 + ∠3 = 180° ; Sum of transversal angles is 180°
So,
∠1 = 180 - 57 = 123°
∠2 = ∠3 ; Vertical angles are ≅
So, ∠2 = 57°
∠1 = ∠4 ; Vertical angles are ≅
So, ∠4 = 123°
∠1 = ∠5 ; Corresponding angles are ≅
So, ∠5 = 123°
∠2 = ∠6 ; Corresponding angles are ≅
So, ∠6 = 57°
∠6 = ∠7 ; Vertical angles are ≅
So, ∠7 = 57°
∠5 = ∠8 ; Vertical angles are ≅
So, ∠8 = 123°

K=6.5
We move all terms to the left:
k-(6.5)=0
We add all the numbers together, and all the variables
k-6.5=0
We move all terms containing k to the left, all other terms to the right
k=6.5
Answer:
1. A
2. I cant see answer<u> D</u>
But if it's 36
<u>IT'S CORRECT</u>
Answer:
C
Step-by-step explanation:
The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)
So for this, you need to know the quadratic formula, which is:
<em>*ignore the weird capital A, it keeps coming up when i try to use the ± symbol</em>
They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that 
comes first.
<u>So now we have the equation: 3</u><u> - 2x +1</u>
*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of , b is always the coefficient of x and c is always the constant (number without an x)
<u>So, i can find that, in this case:</u>
a = 3 b= -2 c=1
<u>Now substitute each of those values it into the original quadratic equation:</u>
<u />
<em>*again, ignore the weird capital A. </em>
That's how you find the answer, which from what i can tell in the picture is C.
Hope that helped : )
