−4(5 − 3x) = 12x + 20
Solve for x:
First use the Distributive property:
-20 + 12x = 12x +20
Add 20 to both sides:
12x =12x + 40
Now you can't get X by itself, because both sides of the equation have the same quantity of x ( they both have 12x).
This means there is no solution.
We know that
the radius is 65 ft
circumference of a circle=2*pi*r
for r=65 ft
circumference of a circle=2*pi*65-----> 130*pi ft
if 2*pi (full circle) has a length of----------------> 130*pi ft
x------------------------------------------> 92 ft
x=92*2*pi/(130*pi)----------> x=1.4154 radians-------> x=1.42 radians
the answer is
1.42 radians
So the new total is:
9 * (44*.8) since the 20% discount means you only pay 80% of the original $44 per item
Answer:
20 blue fish
Step-by-step explanation:
Number of blue fish = x
Number of red fish = x+10
Red fish = 60% of total = 0.6
Total fish = x+x+10 = 2x+10
0.6 = (x+10)/(2x+10)
Solve for x:
1.2x+6 = x+10
0.2x = 4
x = 20
