15, median is the number in the middle, (i.e. median of 3, 4, 8, 9, 10, is 8.)
It's suppose to be -18 so I guess no real number....
Answer:
B 6 centimeters
Step-by-step explanation:
y = x + 2
2x + 3y = 36
substitute y = x+2 into the second equation
2x + 3 (x+2) = 36
distribute
2x + 3x+ 3*2 = 36
combine like terms
5x+6 = 36
subtract 6 from each side
5x +6-6 = 36 -6
5x = 30
divide by 5
5x/5 = 30/5
x = 6
the short side is x =6
the longer side is
y= x+2
y = 6+2
y =8
1. A. y and 1.2y are like terms. c they both contain the same term (y) and can therefore be combined.
2. B. 12x+11 (you have to combine the like terms)
3. 15y+18-4
C. 15y+14 (you must distribute the 3 to inside the parentheses, so 3×5y and 3×6)
4. 9(9-3p) (you have to find a common factor between the terms, in this case 9, and you place it on the outside of the parentheses, while dividing that factor from those terms, which are placed in parentheses.
