Answer:
b right handed boys
Step-by-step explanation:
When we say "solve for the variable", we mean to solve the equation because the solution of the equation is finding the unknown variable.
So, the similarity between "solving for a "variable" to "solving an equation" is that both actions imply looking at the value of that variable.
<h2>Similarity:
both actions imply looking at the value of that variable.</h2>
On the other hand, a slight difference would be in the case of having several variables in the equation. In this case, both actions could represent slight differences, because if we have three different variables and we say "solve for <em>y</em>", that means we must isolate that variable, and the result is just an expression. But, if we say "solve the equation"
<span>System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to two times the second equation in system 1
This is the correct answer because not only is it true but it also follows the property of solving systems of equations with adding the equations. To prove that it is true:
2nd equation in system #2 = 1st equation in system #1 + 2(2nd equation in system #1)
</span>10x − 7y = 18 == 4x − 5y = 2 + 2(<span>3x − y = 8)
10x - 7y = 18 == 4x - 5y = 2 + 6x - 2y = 16
10x = 7y = 18 == 10x - 7y = 18</span>
Answer: just follow these simple steps!
Step-by-step explanation:
1. Estimate the quotient.
2. Perform the division. Remember to place a zero in the quotient when the divisor is larger than the dividend. ...
3. Compare your estimate with your quotient to verify that the answer makes sense.
