Solve for L: d=LM/R2+R1

Answers

d=LM/(R2+R1)
d(R2+R1)=LM
[d(R2+R1)]/M=L

Answer:

Given the equation: $d = (LM)/(R_2+R_1)$ .....[1]

Cross multiply states that an equation of fractions when each of the side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and equating these two products obtained.

Apply the cross multiply in [1], we get;

$d(R_2 +R_1) = LM$

Divide both sides by M we get;

$L = (d(R_2+R_1))/(M)$

$L = (dR_2+dR_1)/(M)$

Y=2x-1 Graph the equation? (steps please thanks!)

Answers

$y=2x-1\n\ny-intercept\ (x=0)\n\ny=2\cdot0-1=-1\to(0;-1)\n\nx-intercept\ (y=0)\n\n2x-1=0\n2x=1\nx=0.5\to(0.5;\ 0)$

There are many ways to graph this equation.
Here's one that you should be able to manage:

-- Pick any number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .

-- Pick any different number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .

-- Using your pencil and ruler, connect the two points that you have marked
on your graph. Without moving the ruler, you may extend the line as far as you
want in each direction.

If Leah is 6 years older than her sister,Sue, and John is 5 years older than Leah, and the total of their ages is 41. Then how old is Sue?

Answers

Let us assume the age of Sue = x years
Then
Age of Leah = x + 6
Age of John = 5 + (x + 6)
= x + 11
Total of their ages = 41
So
x + x + 6 + x + 11 = 41
3x + 17 = 41
3x = 41 - 17
3x = 24
x = 24/3
= 8 years
So Sue is 8 years old.

She is 30 years old.
