Answer:
See below
Step-by-step explanation:



The equation has no solution because no matter what the value we plug for
in the equation, it will not be true and will lead to a contradiction. This is the meaning of not having a solution.
Multiply .03 by 42
.03×42=1.26
1.26kg + 42kg= 43.26
Answer: 43.26kg
A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.
Hope this helps :)
The first answer is 2
The Second is 8
The third is, if the w changes then the p would change as well resulting to multiplication
Hope this helps!!!
