Answer:
250 divided by m= how many students had to solve the math problems.
Answer:
The error is located in step 9, because the student made the following operation:
, instead of
, presented in step 4) of our demonstration. The real solution is 9.
Step-by-step explanation:
First, we proceed to show the appropriate process to solve the equation for
by algebraic means. That is:
1)
Given
2)
Definition of substraction
3)
Distributive property
4)
/
5)
Compatibility with addition/Commutative and associative properties
6)
Existence of additive inverse/Modulative property
7)
Compatibility with multiplication/Commutative and associative properties
8)
Existence of multiplicative inverse/Definition of division/Result
The error is located in step 9, because the student made the following operation:
, instead of
, presented in step 4) of our demonstration. The real solution is 9.
Remark
This question requires a proportion. We will set the body weight on top and the medicine on the bottom. That way the body weight (x) is in the numerator of one of the ratios.
Givens
Body weight1 = BW1 = 104
Medicine 1 = med1 = 130
Body Weight 1 = x
Medicine 2 = 278.74
Formula
BW2 / Med2 = BW1/ Med1
Sub and Solve
x / 278.75 = 104/130 Calculate the right side
x / 278.75 = 0.8 Multiply both sides by 278.75
x = 278.75 * 0.8 = 223
Conclusion
The Patient must have weighed 223 pounds.
Yes because it would read five hundred eighty four thousandths
