Answer:
-6p -10
Step-by-step explanation:
-12 - 6p - (-2)
Subtracting a negative is like adding
-12 - 6p + (2)
Combine like terms
-6p -12+2
-6p -10
Answer:
120:72:48
Step-by-step explanation:
Remark
Whatever the answer is (call it x to begin with), the equation starts as
5x + 3x + 2x = 240
What this means is that when you solve for x the results when multiplied by the ratio, should add to 240
Equation
5x + 3x + 2x = 240
Solution
Combine all the terms on the left.
10x = 240 Divide by 10
x = 240/10
x = 24
Check
- 5*24 = 120
- 3*24 = 72
- 2*2<u>4 = 48</u>
- Total = 240

Answer: 3.01
Step-by-step explanation:
We know that is the population mean unknown , then the sample mean is the best point estimate for population mean .
Let be the population mean weight of packages of ground ground chuck labeled "3 pounds."
Given : A sample of 36 packages reveals the mean weight to be 3.01 pounds.
i.e. sample mean = 3.01
Then, the estimated population mean should be 3.01.
Hence, the estimated population mean= 3.01
Answer:
y=8
Step-by-step explanation:
4−2y+3=−9
Step 1: Simplify both sides of the equation.
4−2y+3=−9
4+−2y+3=−9
(−2y)+(4+3)=−9(Combine Like Terms)
−2y+7=−9
−2y+7=−9
Step 2: Subtract 7 from both sides.
−2y+7−7=−9−7
−2y=−16
Step 3: Divide both sides by -2.
−2y
−2
=
−16
−2
y=8
