You just slide the decimal 2 places over so it would be 0.22
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.
The general idea is that you want to find a variable that has a coefficient of 1 or -1.
In 2.5x - 7y = 7.5, both variables have “bad” coefficients.
In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
For this case we have the following expression:
7 × 10 = 70
Where, by definition:
7: multiplying
10: multiplier
By definition we have that the multiplier equals the number of times the multiplicand must be added.
Therefore, 7 * 10 is to add 10 times 7:
7 * 10 = 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 70
Answer:
Multiplier
The answer would be 21 good luck hope you get it correct
