Answer:
x = -19
Step-by-step explanation:
Multiply both sides of the equation by -9.
x - 26 = -45
Add 26 to both sides.
x - 26 + 26 = -45 + 26
x = -19

Answer:
Mean: 8,75
Median: 7,5
Step-by-step explanation:
To find Mean
To find the mean data you have to put data all set in order:
3, 4, 6, 6, 9, 12, 15, 15
Then, all of the numbers in the data set added together and then divided by how many numbers in the data that already put in order:
3 + 4 + 6 + 6 + 9 + 12 + 15 + 15 = 70
There are 8 numbers in the data so divide 70 by 8:
70 ÷ 8 = 8,75
----
To find Median
The median is in the middle number of the data that already in order. Which is number 6 and 9.
Median = (6 + 9) ÷ 2
Median = 15 : 2
Median = 7,5
Its in that exact order haha
greatest to least:
1/4, 1/5, 1/8, 1/10
Hello from MrBillDoesMath!
Answer:
152 in^2
Discussion:
Surface area =
2 (area of side triangle + area of rectangle face) +
area of bottom rectangle
= 2 ( (1/2) 6*4 + 5*8 ) + 8*6
= 2 ( (1/2) 24 + 40 ) + 48
= 2 (12 +40 ) + 48
= 2(52) + 48
= 104 + 48
= 152
Thank you,
MrB
