6 x 94
= 6(90 + 4)
= 6 x 90 + 6 x 4
= 564
Answer:
20/7 or 2 and 6/7
Step-by-step explanation:
This equation works out to 2/1 • 10/7, which we can easily see equals 20/7, or 2 and 6/7, by multiplying the numerators and denominators.
<h2>Steps:</h2>
(Let x = greater number and y = lesser number)
So this question is asking us for a system of equations. Using the info they provide, we can form these two equations:
So for this, we will be using the substitution method. Since we know that x = y + 7, substitute x with (y + 7) in the second equation as such:
From here we can solve for y. Firstly, distribute 3 so that it multiplies with y and 7:
Next, subtract 3y on both sides of the equation:
Lastly, subtract 5 on both sides of the equation:
Now that we know the value of y, we can substitute it into either equation to solve for x:
<h2>Answer:</h2>
<u>In short, 16 is the lesser number and 23 is the greater number.</u>
The answer is -10xy
(10x^2)(-5y^3)/5xy^2
=-50x^2y^3/5xy^2
=-10x^2y^3/xy^2
=-10xy
x^2/x is the same thing as X^2-1
y^3/y^2 is the same thing as Y^3-2
