Answer:
The average of the diameter readings is 4.34 cm.
Step-by-step explanation:
We are given the following data set(cm):
4.32, 4.35, 4.31, 4.36, 4.37, 4.34
Formula:
Thus, the average of the diameter readings is 4.34 cm.
The two numbers are 7 and 4
7x - 9 < 12
7x < 12 + 9
7x < 21
x < 21/7
x < 3
1/4x + 8 > 11
1/4x > 11 - 8
1/4x > 3
x > 3 * 4
x > 12
solution : x < 3 or x > 12
Answer:37.45hStep-by-step explanation:
you do 0.07 times 35 which gives you 2.45 then you carry the h over and add that to 35 which gives you 37.45h
The answer to <span>-7(k+9)=9(k-5)-14k is
k = -9
</span>-7(k+9)=9(k-5)-14k
Use the distributive property to distribute the -7 to (k+9) and 9 to (k-5)
-7(k+9)=9(k-5)-14k
-7k - 63 = 9k - 45 - 14k
Now lets get all our constants on one side of the equal sign and all our terms such as 9k and 4k on a side by their self
-7k - 63 = 9k - 45 - 14k
-7k - 63 + 45 = 9k - 45 + 45 - 14k
-7k - 18 = 9k - 14k
Now lets get that -7k on the right side
-7k + 7k - 18 = 9k - 14k + 7k
-18 = 9k - 14k + 7k
Now lets do the math for 9k - 14k + 7k and solve for k
-18 = 9k - 14k + 7k
-18 = 2k
-18 / 2 = 2k / 2
-9 = k
k = -9
