Do not copy any others will make brainleist again dont copy any one else part a: explain why x = 3 makes 4x − 1 ≤ 11 true but not 4x − 1 < 11. (5 points) part b: what value from the set {4, 5, 6, 7, 8} makes the equation 8x + 1 = 57 true? show your work. (5 points)

Part A: If 3 is equal to x, we can substitute it into the equation. The equation would look like this: 4(3)-1 ≤ 11

We can simplify the equation using multiplication: 12-1≤11

Now, we do subtraction: 11≤11

This is true because ≤ means less than or equal to. If we substituted ≤ for <, it would no longer be true because 11 is not less than 11.

Part B: We need to substitute every number in. I will go top to bottom until we determine our answer. 8*8=64, so it cannot be 8 because 64+1≠57

8*7=56. Now, we add 1 to 56 and we get this: 57=57

This is true because they are the same number, therefore equal.

The value "7" would make the equation true.

If you need any more help, feel free to let me know!

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
