To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
Answer:
7.) 16.7
Step-by-step explanation:
7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle
Using the pythagrorem theorem a² + b² = c²
4² + b² = 5²
b² = 5² - 4²
b² = 25 - 16
b² = 9
√b² =√9
b = 3
next you do the same thing to find the missing segment of the longest side
3² + b² = 13²
b² = 169 - 9
b² = 160
b = √160 or ≈ 12.7
12.7 + 4 = 16.7
so 16.7 is the length of that side
So put it in 2 hours and 15 minutes before 6pm which would be 3:45
To figure out the answer to this problem, you must first ask yourself this:
<span>
</span><span>How much is 126 of 700
</span> or
<span>What is 126 divded by 700
</span>
The answer is 0.18.
So, that means that 0.18 or 18 percent might be your answer.
Now, lets try 18 percent of 700, to see if we get 126.
<span>18% times 700
</span>
The anwer is 126.
SO:
$126 is 18 percent of 700.
18 percent of her sale is Destiny's commission.
