Hi there! :)
Answer:
4/7 times 35, minus 8.5 is no more than 11.5
The number is : 35
Step-by-step explanation:
Let's replace "a number" by the letter "x" because that's what we are looking for.
4/7 × x = 4/7x
4/7x MINUS 8.5 = 4/7x - 8.5
The expression "no more than" is represented by this sign: ≤
"No more than" can also be "less than or equal to".
The final inequality should look like this:
4/7x - 8.5 ≤ 11.5
Now all you need to do is solve the inequality by isolating "x":
4/7x - 8.5 ≤ 11.5
Add 8.5 to each side of the inequality → 11.5 + 8.5 = 20
4/7x ≤ 20
Divide each side of the inequality by "4/7" → 20 ÷ 4/7 = 35
x ≤ 35
There you go! I really hope this helped if there's anything just let me know! :)
I popped in the values to desmos, and it doesnt make a line. i dont think it is a proportional relationship... either that or im dumb lol sorry
