Answer:
-6°C
-15°C
-1.5°C
Step-by-step explanation:
The computation is shown below:
in one hour the temperature falls by 3°C i.e.
= 0 - 3
= -3°C
In two hours
= 2 × - 3°C
= -6°C
In five hours
= 5 × -3°C
= -15°C
in half an hour
= 0.5 × -3°C
= -1.5°C
For this case we must write algebraically the following statement:
<em>"The sum of p and q is equal to 24"</em>
The sum of p and q is represented as:
If the sum is equal to 24 we have:
If they tell us that 
, then the expression is:
Answer:
Given equation is 
If we substitute x = 0, then, y = - 4.
So, (0, -4) is a point on the line.
If we substitute x = - 6, then y = 5 - 4 = 1.
So, (-6, 1) is another point on the line.
Joining (0, -4) and (-6, 1), we get the graph of the line.

Answer:
The bracelet will cost 85$ and it'll have 2 charms.
Step-by-step explanation:
In order to find the total cost of the bracelet and how many charms it'd be we need to build an equation for each store. So we have:
Oak Grove:
total cost = 16*charm + 53
Sandoval:
total cost = 27*charm + 31
We then find the number of charm that'll make them equal, since the price has to be the same on both shops:
16*charm + 53 = 27*charm + 31
27*charm - 16*charm = 53 - 31
11*charm = 22
charm = 2
The cost of the bracellet is:
total cost = 27*2 + 31 = 85 $
