Answer:
Step-by-step explanation:
Please type numerals and punctuation for your mixed numbers.
I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:
-1 1/3 -1 2/6
-2 5/6 -2 5/6
----------
-3 7/6 or -4 1/6
The best calculation of this difference is -4 1/6 and the best estimate is
-1 - 3, or -4

Expression to rationalize the numerator and denominator of the above
To rationalize means to reduce a surd to a rational form by multiplying the surd by a suitable surd is know
To rationalize the above surd, we multiply the numerator and denominator by the surd expression at the denominator, which is
<em>Solving further to rationalize the given expression, we have</em>
Multiply
Expand the expression to give
Simplify by dividing numerator and denominator by 3
Expand denominator
Square root of 4 is 2 and square root of is x, so we have
Hence, rationalizing will give
y = - 7x - 20
the equation of a line in ' slope- intercept form ' is
y = mx + c → (m is the slope and c the y- intercept)
here m = - 7 ⇒ y = - 7x + c
to find c substitute ( - 4 , 8 ) into the equation
8 = 28 + c ⇒ c = 8 - 28 = - 20
y = - 7x - 20 → equation in slope- intercept form
Answer:
Step-by-step explanation:
Division property of equality states that you divide the same number to both sides of an equation.
Given the formula:
...[1]
Solve for G:
Apply the division property,
Divide both sides by Mr in equation [1] we have;
Simplify:
or
Since both 4 and 6 are divisible by 2, it becomes 2/3<span />
