Answer:
assume an approximate value for the variable that will simplify the equation.
solve for the variable.
use the answer as the second approximate value and solve the equation again.
repeat this process until a constant value for the variable is obtained.
11 and 12
7 and 512
12 and 10
0 and 78
left side numerator
right side denominator
25% 6 divided by 24 will give you the percentage of copper in the bar
Here is the set using D = rt.
Jet 1:
rate = 377 mph
time = x
Distance = 9128 miles
Jet 2:
rate = 275 mph
time = x
Distance = 9128 miles
Equation:
377x + 275x = 9128
You finish.
Add 1/7 to both sides to get 2/7m=3/14+1/7 find common denominater (14) so multipy 1/7 by 2 to get 2/14 than add that to 3/14 to get 5/14 than take 2/7 and 5/14 turn into a decimals than divide the 2/7 on both sides to get m=?
