Answer:
Step-by-step explanation:
1) 5 - [-5] = 5 + 5 = 10
2)8 - 13 = 8 + (-13) = -5
3) 12 +(-3) = 9
4) x + (-7) = 5
x - 7 = 5
x = 5 + 7
x = 12
We need to add 12 to (-7) to get 5
5) 7 - x = -5
7 = -5 +x
7 + 5 = x
12 = x
We need to take away 12 to 7 to get (-5)
6) 7 - (-10) = 7 + 10 = 17

Answer:
31 servings
Yes there would be leftover
Step-by-step explanation:
In this question, we are asked to calculate the amount of a certain volume that would be had and if there also would be leftovers.
Firstly, to solve this question, we need to know the total volume made by the siblings.
Let’s convert What Jeniffer made to liters. It must be known that 1000ml is 1L. This means her 5L would be 5 * 1000 = 5000ml
Let’s add this to what her brother has and it would be 5000 + 750 = 5,750ml
Now they made a series of 180ml servings. We need to know how many of these would they have. We simply make a division: 5,750/180 = 31.94
There would be 31 of this and also there would be a remainder
You can express 0.000036 as 3.6 × 10^-5 (we move the decimal 5 places left)
Then we find 3.6 × 10^-5 × 20.5 × 10^7
The exponents add to become just 10^2.
3.6 × 20.5 = 73.8
73.8 × 10^2 is our answer...
In proper scientific notation, this is 7.38 × 10^3. (the left # should be <10)
In standard notation, this is 7380. (we move the decimal 3 places right)
Answer:
37 birdhouses
Step-by-step explanation:
Given:
It takes 1/3 pint of paint to cover a birdhouse.
There are 12 1/3 pints of paint in a can.
Question asked:
Write and evaluate a division expression to find the number of bread houses that can be painted.
Solution:
<em><u>We will solve it by unitary method:</u></em>
By using 
pints of paint, we can paint = 1 birdhouse
By using 1 pints of paint, we can paint = 
By using 
pints of paint, we can paint 
Thus, 37 birdhouses can be painted by using pints of paints.
