Answer:
8n + 5 = 69
And that number is 8, because 8•8+5=69
Step-by-step explanation:
"eight times a number and five is sixty-nine" in this statement the words "a number" is the number we dont know and so we use a variable for it. I put n, but you could have used x or a or any variable. The "and five" indicates adding. The "is" indicates equals.
-.5 + 2, you can think of this as 2 - .5 as well, it would equal out to be 1.5.
