You can set up a proportion: 1/4 inch = _ X 20 miles 216 miles Cross multiply: (1/4 inch)*(216 miles) = x * (20 miles) Combine & Cancel: 1/4*216...

If one person takes X days to do a job and another takes Y days to do a job, the time it takes them to do it together is XY . X+Y So, if, in this problem, the job together takes 28/11 days, then X * Y = 28 and...
What is the actual problem? So far, you have only defined a function and given the first term.
If you see a question like this, that looks like straightforward arithmetic, but involves multiplication, division, addition, and subtraction (or any combination of those), you should be thinking "This is probably testing me on Order of Operations." With Order of Operations,...
Question 1 asks you to look at a line representing how far Manuel walks (y-axis) based on how long he's been walking (x-axis). Because it's a straight line, you know he walks at constant speed. Then, you have to look at other data points to determine which of them would also appear on...
Your actual values are 14 peanut butter cookies out of 56 total cookies. Make that a fraction: 14 pb 56 total Reducing that fraction by dividing numerator and denominator by 14 (the greatest common factor) , you get 1 peanut butter cookie...
To solve for the value of the check you must take into account that the teller transposed the dollars and cents. (e.g. gave you 41.56 when the check was supposed to be 56.41). This means that you must represent the dollars and cents as different variables within the same number (e.g. $d.c) ...
Remember the rules for order of operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (PEMDAS) There aren't any Parentheses or Exponents,, so the next step is Multiplication and Division. 5 times 10 is 50, so the new equation is 50 + -18 = n + 55 Next...
Assuming the original problem is: [(m/4)*(n/3)]-1 divided by [(-5m/-3)*(n4)]2 The numerator becomes (mn/12)-1. Any fraction to the -1 power is just flipped, so this becomes 12/mn The denominator becomes (-5mn4/-3)2 Squaring a fraction means squaring its numerator and denominator,...
