Answer:
2p+2+p = 20
Step-by-step explanation:
Let p represent the number of Math problems Hayden completed.
Let 2p+2 represent the number of Math problems Jamie completed.
Next, we have to<u><em> add them together</em></u> so that the total Math problems they completed will be equal to 20.
Let's solve.
- 2p+2+p = 20
- 3p+2 = 20
- 3p = 20-2
- 3p = 18
- p =
Therefore, Hayden completed 6 Math problems.
Next, we have to get how many problems Jamie completed.
Let's solve.
- 2p+2 = ?
- 2(6)+2 = ?
- 12+2 = ?
- 14
Therefore, Jamie completed 14 Math problems.
Let's check.
It's correct!

You have to evaluate the slopes of these lines. For line AB you have a slope of
For line CD you have a slope of
Because the slopes are equal and the two lines are not one and the same, they are parallel.
On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions
13.8 + (-11.5) and (-13.8) + 11.5 are numbers will same value and opposite sign.
<h3>What are rules for adding a positive and a negative number?</h3>
For adding a negative and a positive number, use the sign of the larger number and subtract.
For example: (–8) + 2 = -6
Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)
13.8+(-11.5) = 13.8-11.5 =2.3
13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8
but (-13.8) + 11.5 = -13.8 +11.5 = -( 13.8 -11.5) [taking -1 common from the expression]
Therefore , -13.8 + 11.5 has same value as 13.8- 11.5 but opposite in sign.
