mean = (sum of values) / (number of values)

we know mean is 13 and we are given 8 values. The ninth value is the missing x:

13 = ((sum of 8 values) + x)/9

13 = (12+10+15+12+13+15+11+15+x)/9

13*9 = 103+x

x = 14

The missing value is 14. There are 14 pillows in the last box.

What is the length of side ac of the triangle
Margarita [4]

Answer:

AC = 25

Step-by-step explanation:

Since ∠A = ∠C then the triangle is isosceles, thus BC and AB are congruent, that is

BC = AB, substitute values

7x - 1 = 5x + 5 ( subtract 5x from both sides )

2x - 1 = 5 ( add 1 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Hence

AC = 6x + 7 = (6 × 3) + 7 = 18 + 7 = 25
