Answer:
53
Step-by-step explanation:
they are a linear pair so x + 2x + 21 = 180 so you subtract 21 from both sides, combine x and 2x then divide by 3 to get 53
Answer:
Age of Rocky = 5 months
Step-by-step explanation:
Given that:
Equation for calculating puppy's weight
p = 3a + 2
Here,
p = weight of puppy
a = age in months
We have to find the age if the weight is 17 pounds
Putting p=17 in given equation
17 = 3a + 2
17 - 2 = 3a
3a = 15
Dividing both sides by 3
Hence,
Age of Rocky = 5 months
X< -6
Solve for the inequality x
Answer:
Difference between Observational and Experimental Data
The data collected in the study is observational data.
Step-by-step explanation:
In an experimental study, the data collected is divided into two groups. One group is the control group. The other group is the treatment group (also known as the experimental group). Data is gathered about the groups in order to compare their different outcomes and to draw conclusions if there is any causality based on the two variables. With observational data, the researcher is interested in observing the variables to determine if there is any correlation.
4/12 and 6/18 because all the fractions (2/6,4/12, and 6/18) reduce down to 1/4.
