1. How do you subtract an integer from another integer without using a number line?
2. Rewrite each following subtraction problems as addition problems
1) 5-11 2) 15- 21
3) 0-(-5) 4) 19-(-19)
5)-3-(-5) 6)-87-(-87)
7)-17-1
3. When Tom found the difference -11-(-4), he got -15. What might Tom have done wrong?
4. When you subtract one negative integer from another, will you answer be greater than or less than the integer you started with? Explain your reasoning and give an example.
5. Theo had a balance of -$4 in his savings account. After making a deposit, he has $25 in his account. What is the overall change to his account? Show all your steps.
Answer:
1) Remember to change the signs when necessary. For example, when you're subtracting a negative with another negative, you add the two numbers to form a bigger negative.
2)
1)) -6 + 11 = 5
2)) -6 + 21 = 15
3)) 5 + 0 = 0
4)) 19 + 19 = 38
5)) (-5) + (-3)
6)) -87 + 87 = 0
7)) -1 + -17 = -18
3) Tom didn't change the sign to make a +, instead he left it as one negative sign and a subtraction sign.
4) The answer will be of a greater value as the two negatives would cancel each other out. For example, -9 - (-9) would end up being 0 as the sign change would make one 9 positive.
5) $-4 + $29 = $25 He added $29 dollars to his bank account, turning himself out of debt.

Figure D’E’F’G’ is a dilation with center (0, 0) of figure DEFG. What is the scale factor?
Answer:
0,0
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Lets start by finding out the cordinates first!
these are the ones we start off with!
D (1,1)
E (2,2)
F (4,2)
G (3,1)
now we need to find the prime image cords.
D' (4,4)
E' (8,8)
F' (16,8)
G' (12,4)
now what we are tying to find is the scale factor, so we need to check what number is multipled by those cordinates to get the prime cordinates.
D is (1,1) and D' is (4,4) but we know that 1x4 is 4 so 4 is the scale factor that we multiply all the numbers by ! i hope that made sense !

The length of the track is 377.6 feet
What is the area of the square?The area of the square is defined as the product of the length and width.
Given that area of the square is 128 square feet.
The sides can be found by taking the square root of the area.
The area of the square = s², where s = side.
⇒ s =√(Area)
⇒ s = √(128) = 11.3
So the length of one side of the square is 11.3 feet.
Since the circumference of a circle = πD
Here D = 11.3 feet.
So circumference of a circle = π(11.3) = 355 feet
The length of the track = 2(11.3)+ 355 = 377.6
Thus, the length of the track is 377.6 feet

Which size can of soup shown in the table has the lowest unit price?
The can of size 10 has the lowest unit price.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity.
We have to find the unit rate.
For size 10 :
Cost of 10 oz of soup = $0.79
Cost of 1 oz of soup = 0.79 / 10 = 0.079
For size 15 :
Cost of 15 oz of soup = $1.29
Cost of 1 oz of soup = 1.29 / 15 = $0.086
For size 18 :
Cost of 18 oz of soup = $2.16
Cost of 1 oz of soup = 2.16 / 18 = $0.12
For size 32 :
Cost of 32 oz of soup = $3.19
Cost of 1 oz of soup = 3.19 / 32 = $0.0997
The smallest unit price is for can of size 10.
Hence the lowest unit price is for the can of size 10.
