Using the "map scale", imagine you are hiking and using a map with a scale of 1: 24,000. if you plan out a route, measure it and find that it is 10 inches total on the map, what is the actual distance you will walk on that route

After tracing  out your route, pull the string straight and  measure  it against the  scale  line in the  maplegend. another method is  to use  a compass (the mathematical kind) set to a narrow  distance  on themap scale  like mile and then "walk  off"  your route. it is a good idea to be conservative and add 5-10% of the  total distance 

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

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!
