Answer:
y = 11
Step-by-step explanation:
We use the definition of Supplementary Angles and Adjacent Angles.
Step 1: Set up equation 1 (Definition of Supplementary Angles)
5x - 4 +7x - 8 = 180
Step 2: Solve for <em>x</em>
12x - 4 - 8 = 180
12x - 12 = 180
12x = 192
x = 16
Step 3: Plug in <em>x</em>
5(16) - 4
80 - 4
76°
Step 4: Set up equation 2 (Definition of Supplementary Angles)
76 + 9y + 5 = 180
Step 5: Solve for <em>y</em>
9y + 81 = 180
9y = 99
y = 11

Answer:
a. 14
b. 7
Step-by-step explanation:
a. First we must add all the animals together,
Total Animals:
Birds: 6
Fish: 5
Mammals: 11
Reptiles: 3
Therefore our equation is:
6 + 5 + 11 +3 = 25.
Now, we must subtract by the number of mammals:
25 - 11 = 14
So our answer for a. is 14!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!
Mammals + Fish =
11 + 5 =
16
Next,
Birds + Reptiles =
6 + 3 =
9
Now, let us subtract them,
16 - 9 =
7
So our answer for b. is 7 more animals!
Answer:
$0.75 per song
Step-by-step explanation:
Given that the relationship between variable s and c is a proportional relationship, and is represented by the equation, c = 0.75s.
Where,
c = total costs
s = number of songs
The constant of proportionality, k, = 0.75.
Thus, 0.75 represents the cost per sing downloaded.
The answer is:
✔️$0.75 per song
