For this case we must solve the following linear equation:

Adding similar terms from the left side of the equation:

Subtracting
from both sides of the equation we have:

Thus, equality is not fulfilled. So the equation has no solution.
Answer:
No solution
Answer:
12
Step-by-step explanation:
The proportion is equal to 
We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

Dividing both sides by 5, we have the answer as

Answer:

Answer:
$2.69
Step-by-step explanation:
Distribution method:
.20(2.50, 4.95, 6.00)
(0.50, 0.99, 1.20)
Now add them up.
Non-distribution method:
$2.50 x .20 = 0.50
$4.95 x .20 = 0.99
$6.00 x .20 = 1.20
Add them up
