An expression involves subtracting two numbers from a given first number under what circumstance will the value of the expression be negative

Say that you start from a number . Then, you subtract and from , which means that the expression is

If we want this expression to be negative, we have

So, in order for the expression to be negative, the two numbers we are subtracting, combined, must be more than the starting number.

For example, if we start from 10 and we subtract 4 and then 8, we have

which is negative, because 4 and 8 combined are more than 10

e2020 got it right

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
