If twice a number is at least three less than four times the number, which of the following are true? let n represent the number.

Step-by-step explanation:

Let n represent the number

Twice the number =2n

4 times the number = 4n

Given that twice the number is atleast 3 less than four times the number

Algebraically this can be written as

2n≤4n-3

We can add 3 to both sides

So n should be atleast 1.5

If n is natural number or integer then least value of n is 2.

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
