Answer:
The answer is 2j -5 = 230.
Step-by-step explanation:
This is because of what the question is asking. When it says that 5 decreased from DOUBLE Joe's weight is 230 it means that the equation will result in 230. To find the equation we know we need DOUBLE Joe's weight and so it is 2j. It also says 5 decreased from double Joe's weight so we need to take away five. This is how we get to 2j - 5 = 230.
Answer:
a) Joe's weight is: 117.5
b) [tex]2j-5=230[/tex]
Step-by-step explanation:
1. You know that 5 is decreased from double Joe’s weight and the result is 230. Then, if [tex]j[/tex] represents Joe’s weight you can write the following expression:
[tex]2j-5=230[/tex]
2. To know Joe’s weight you must solve for [tex]j[/tex]. Then, you obtain the result show below:
[tex]2j=230+5\\2j=235\\j=\frac{235}{2}\\j=117.5[/tex]
