The equation is: 27.46 = 1.95x + 2.50
The answer is 12.8
Answer:
22.34 
Step-by-step explanation:
The area of a circle:
A = π
The problem gives the diameter of a circle, which is equal to 2*r.
If 5 1/3 = 2*r, then the radius is (16/3)/2 = 8/3.
Plugging this into the area equation,
A = π*
A = 
or approximately 22.34
<h2>x = 1/4</h2><h2>y = -2</h2><h2>______________</h2>
<h2>Known : </h2>
y = -8x
4x - y = 3
<h2>Asked: </h2>
Use the substitution method to solve the system of equations ?
<h2>Answered:</h2>
<h3>Substitution y</h3>
4x - y = 3
4x - (-8x) = 3
4x + 8x = 3
12x = 3
x = 3/12
x = 1/4
<h3>
Substitution x</h3>
4x - y = 3
4(1/4) - y = 3
4/4 - y = 3
1 - y = 3
-y = 3 - 1
-y = 2
y = -2
Answer: Hello, Here you Answer......
132 km
Given that the relationship between kilometers and fuel is proportional, let the distance in km be k and the fuel be f:
thus:
kα cf
k=cf
where k is the constant of proportionality. Thus:
c=k/f
Pamela drove 99 km and used 9 liters;
∴k=99/9=11 km/liter
therefore distance covered is given by:
k=11f
hence the distance covered with 12 liters of fuel will be:
k=11×12
=132 km Hope this helps! (Brainly)♥
