Answer:
-q
Step-by-step explanation:
We know that we are trying to find an expression equivelant to p - q:
p - q can be p - 1q
We can then put parenthesis around -1q:
p + (-1q)
We then can simplify:
p + (-q)
Answer:
The time required by both persons to complete the work T = 1.458 hours
Step-by-step explanation:
Given data
Time required by Joe to clear a lot
= 2.5 hours
Time required by his partner to clear a lot
= 2.5 hours
Time required by both persons to complete the work by working together
![T = \frac{T_1 T_2}{T_1 + T_2}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7BT_1%20T_2%7D%7BT_1%20%2B%20T_2%7D)
![T = \frac{(2.5)(3.5)}{2.5 + 3.5}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B%282.5%29%283.5%29%7D%7B2.5%20%2B%203.5%7D)
T = 1.458 hours
Therefore the time required by both persons to complete the work T = 1.458 hours

Answer:
9d+7
Step-by-step explanation:
when you subtract you 'add the opposite' so we can rewrite this subtraction problem as an addition problem as follows:
6d + 5 + 2 + 3d
combine 'like' terms to get:
9d + 7
Answer:
Step-by-step explanation:
the side with the biggest angel across form it has the longest side
