Why are the solutions to the proportions
- 1o and zo =
the same?
because both result in the equation 8% = 400, which simplifies to %=5
because both result in the equation 8%= 400, which simplifies to %= 50
because both result in the equation 40% = 80, which simplifies to %= 2
because both result in the equation 40%= 80, which simplifies to X=20

Jack has a piece of red ribbon that is two times as long as his piece of blue ribbon. he says that he can use two different equation to find out how long his piece of red ribbon is compared to his piece of blue ribbon is. is he correct? explain his reasoning

If the tip varies directly with the number of guest which equation represents between the tip,t, and the number of guest,g?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
