Answer:
bicep circumference is a measurement of our body part we need to collect all our so we know our body fats.
Answer: x = 4
Step-by-step explanation: To solve this equation, we could go right to our steps of subtracting 5.4 from both sides, but I would do a slightly different approach.
Since I hate working with decimals, I would get rid of them.
We can do this by multiplying both sides of the equation by 10, and remember to multiply every term by 10 to keep it balanced.
*Multiplying by 10 shifts the decimal point 1 place to the right
So we have 35x + 54 = 194 which looks a lot better.
Now subtract 54 from both sides to get 35x = 140.
Now divide both sides by 35 and x = 4.
The fewest boxes is 8 because if you do 7 you are below but if you do 7.5 you can't because you can't use half a box but 8 is a whole box which will fit everything
