What is the mean of 7,5,6,5,4,4,,8,6,6,7,4,5,5,6,6
Alex
The mean is 5.6 and the median and mode are 6
4 x 9 = 36. Plug it back in to see if it is true: 36 / 9 = 4.
Answer:
Step-by-step explanation:
L and W are the length and width of the garden, respectively.
perimeter = 2L+2W = 38 ft
L+W = 19
the length is 5 ft longer than the width
L = W+5
substitution
(W+5)+W = 19
2W+5 = 19
W = 7
Answer:
a) 4x - 8y
b) 4 × x - 8 × y
c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication
Step-by-step explanation:
a) start with the parentheses
1/3 (6x - 12y)
multiply 6x and -12y by (1/3)
2x - 4y
so now the equation is 5x -3x -4y + 2x -4y
add together the like terms
5x -3x + 2x = 4x
-4y -4y = -8y
so we have 4x - 8y
b) im not good with factored form but i believe this is right
take 4x and separate them by turning it into 4 × x and same for -8y turn it into -8 × y
c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication
im not sure how to prove them equal to the original expression i dont really remember that but i hope this helped
