Let,
the bigger number be "x"
the smaller number be "y"
Now, according to the question,
x + y = 24...........equation (1).............because the sum of numbers is 24
x - y = 15 .............equation (2)..................because their difference is 15
Taking equation (2),
x - y = 15
x = 15 + y ....................equation (3)
Now, Taking equation (1)
x + y = 24
(Substituting the value of "x" form equation (3) we get)
15 + y + y = 24
(Subtracting 15 on both sides, we get)
y + y = 24 - 15
2y = 9
y = 9 / 2
y = 4.5
Now,
Taking equation (3)
x = 15 + y
(Substituting the value of y , we get)
x = 15 + 4.5
x = 19.5
So, the two numbers are 19.5 and 4.5
Answer:
12
Step-by-step explanation:
First figure the ratio of the real building to the model which is 21 divide 3. So the ratio is 1:7, since we're finding the height of the model, we divide 7 by 84 which is 12
Answer:

Step-by-step explanation:
First, it is important to remember which are the Negative numbers and the Positive numbers.
The Positive numbers are defined as all those numbers that are greater than zero and the Negative numbers are defined as all those numbers that are less than zero.
Then:
a. "3 degrees below
" indicates that the temperature is actually
, which is less than zero. Then, it is a negative number:

b. Let be 0 represents the sea level, "6 feet above the see level" indicates that the number is positive:

c. "Lost 5 pounds" indicates that now the actual weight is 5 pounds less than the original, which indicates that it must be expressed as a negative number:

d. "Found
" means that now the actual amount of money is greater than it was before. Then, the number that represents this is a positive number:

-2/1
+3
idk if this was what you needed but this is a way to put it on the graph
