Alternate interior angles are congruent. Therefore, set the two angles equal to each other and solve for x.
3x+4= 115
3x+4 -4 = 115 -4
3x = 111
x= 111/3---> 37. Therefore, x = 37.
Answer:
4
Step-by-step explanation
Formula: <em>b * h</em>/ 2 (Base times height divided by 2)
4 x 2 = 8
Divide in half
8/2 = 4
The correct expansion is the one in option b:

How to rewrite the term?</h3>
Here we must use the logarithmic property:

Our expression in this case is:

Using the above property, we can rewrite the expression as:

From this, we conclude that the correct option is B.

Answer:
Step-by-step explanation:
2/3+1/3x=2x
moving all the x to one side
2/3=2x-1/3x
factoring out x
2/3=x(2-1/3)
dividing
(2/3)/(2-1/3)=x
Okay! So 1/4 = 2/8 and 3/8 = 3/8 3/8+2/8= 5/8
3/8 is your answer
