Consider this statement: for every 2 boys, there are 4 girls. do you agree with the statement?

Yes, because the ratio would be 1 boy for every 2 girls, meaning 2 boys for 4 girls would make sense. they could be trying to trick you, but I think it's correct. It's not fully simplified but it still is accurate

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
