Answer:
The First Option
Step-by-step explanation:
y - 7 = -1/4(x - 4)
Essentially, we are trying to find the missing constant term of 
(remember that we are subtracting 
due to the negative sign in front of the second term). Let's expand this to see what we can work with:
Now, we know the second term is 
, so let's set the second term in the polynomial we just found equal to :
- Divide both sides of the equation by
- Divide both sides of the equation by 2
We have found . We know the missing constant term is 
, according to the polynomial we found earlier. Thus, the missing term is:
The missing constant term is 36.
2b + 5j = 6.35.....multiply by -2
4b + 12j = 13.20
----------------------
-4b - 10j = - 12.70 (result of multiplying by -2)
4b + 12j = 13.20
----------------------add
2j = 0.50
j = 0.50/2
j = 0.25 <==== jars
2b + 5j = 6.35
2b + 5(0.25) = 6.35
2b + 1.25 = 6.35
2b = 6.35 - 1.25
2b = 5.10
b = 5.10/2
b = 2.55 <=== brushes
so 1 brush (b) = 2.55 and 1 jar (j) = 0.25...total, if needed, = 2.80
Answer:
1- 19, 2- 27
Step-by-step explanation:
6.05 - 2.25
= 3.8 divided by 0.20
=19
7.65 - 2.25
= 5.4 divided by 0.20
= 27
