the third answer. x represents half of any even number. so half of any even number minus seven equals 1.5 is the answer.
Answer:
x = 14
Step-by-step explanation:
The angles form a straight line which makes them add to 180 degrees
4x+ 8x+12 =180
Combine like terms
12x+12 =180
Subtract 12 from each side
12x+12-12 = 180-12
12x=168
Divide each side by 12
12x/12 =168/12
x =14
This is how I find the GCF.
I find the prime factors.
63/3 = 21
21/3 = 7
7/7 = 1
81/3 = 27
27/3 = 9
9/3 = 3
3/3 = 1
Then I find the common prime factors:
63: 3 x 3 x 7
81: 3 x 3 x 3 x 3
Then I multiply the common prime factors:
3 x 3 = 9
The GCF for 63 and 81 (number 3) is 9.
I bet you can use this method for all the other GCFs! :)
For this one, find the prime factors like before, and if there aren't any besides one, then it's a prime number.
75/3 = 25
25/5 = 5
5/5 = 1
The prime factorization for 75 is 3 x 5 x 5
(I don't know the answer to 7, 8, 9, 10, 11, 12, 25, or 26, sorry!)
Answer:
Step-by-step explanation:
With this being a proportional relationship, the y-intercept MUST be 0.
Thus, the relationship has the form y = C(x) = ($5/movie)x, where x is the number of movies purchased.
To graph this, first plot a dark dot at (0, 0). Then, starting at (0, 0), move your pencil point 1 unit to the right and from this new position 5 units up. Plot a dark dot at (1, 5). Now draw a straight line through (0, 0) to the right through (1, 5).
Total surface area of a triangular prism = width x height +(sum of sides + width) x length
475 = (width x 10) + (5 + 5 + width) x 15
475 = (10 x width) + (10 + width) x 15
475 = (10 x width) + 150 + (15 x width)
475 - 150 = 25 x width
325 = 25 x width
width = 325/25 = 13 feet
