As for this, we have to take in the given equivalents and work with them to get the commission for selling each suit and each pair of shoes.
Let us put first that each suit is represented with a and for each pair of shoes, we represent them with b.
The given equations would be these:
47 = 3a + b
107 = 7a + 2b
Now we use the first equation to use for substitution purposes. We would first determine b in the process. To find b, we would be utilizing the equation
b = 47 - 3a
We then move to substitution.
107 = 7a + 2b
107 = 7a + 2(47 - 3a)
107 = 7a + 94 - 6a
107 - 94 = 7a -6a
13 = a
now that we have the value for a, we then use it to find b.
b = 47 - 3a
b = 47 - 3(13)
b = 47 - 39
b = 8
So the answer would be 13 for each suit and 8 for a pair of shoes.
Answer:
He needs 3.75 lbs of sugar and 1.25 lbs of water.
Step-by-step explanation:
Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.
Note
5 lbs - 100%
x lbs - 75%
Write a proportion:
Cross multiply:
So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.
Step-by-step explanation:
after one hour red is 18 inches
blue is 7 inches
after two hour
The correct term to fill in the blank would be discussion. When evaluating an observational study, the four factors that should be reviewed are Introduction, Methodology, Results, and Discussion. In an observational study, the researcher cannot control the variables. The researcher wold draw some inferences from a set of sample without controlling anything.
