Tank A has 35 gallons of water and is filling up at a rate of 5 gallons per minute,
Tank B has 100 gallons of water and is
draining at a rate of 8 gallons per minute,
Solve the following system of equations,
In how many minutes will the tanks
contain the same amount of water, and
how much water will that be?
Sy = 35+ 5x
y = 100 - 8x

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.
