"More" in a word problem means addition is involved. "Half" indicates division by 2 (or multiplication by 1/2). "A number" means a variable, so we can us x. Finally, "is" mean equals. So, 15 more than half a number is 19 would be represented as follows:
15 + x/2 = 19
Solving this, we get:
15 + x/2 = 19
x/2 = 4
x = 8
x/2 + 5
n/2 + 3 = 21
8/15 would be more than one half because 7.5 is half of fifteen
n/2 + 9≤-8n/2 ≤-17n≤-34
15x + 9
x/2 + 5
yup
n/2 + 3 = 21
8/15 would be more than one half because 7.5 is half of fifteen
n/2 + 9≤-8n/2 ≤-17n≤-34
15x + 9
V+15
5015
Yes, but you can't fold it in half more than 7 times
Let the number be x. By the given statement we can make an equation. 1/2 * x = 18 + 5*x Which gives x = -4. So the number is -4.
Fifteen is three-fourths of what number?
No more than fifteen seconds, maybe a half minute if the horse is tired.
