It is a linear equation in the variable r.

I hope you mean "What is the solution for the problem 5R plus 6 equals 36". In that case 5R + 6 = 36 5R = 36 - 6 5R = 30 R = 6

In a GP each term is the previous term multiplied by a constant. Let the common difference be r, then: x = 5r y = xr = 5rr = 5r² 40 = yr = 5r²r = 5r³ → 5r³ = 40 → r³ = 8 → r = 2 → x = 5 × 2 = 10 → y = 10 × 2 = 20

If: 2p+5r = q Then: p = (q-5r)/2

First, translate it into an algebraic equation:4 + 5r = -11Then we subtract 4 from both sides:4 + 5r - 4 = -11 - 4Now we can simplify our numbers together:(4 - 4) + 5r = -11 - 40 + 5r = -155r = -15Now we divide both sides by 5:(5r / 5) = (-15 / 5)r = -3

r+5r+5=-25

-2r

20 is the GCF. The LCM is 40.

20% of 40= 20% * 40= 0.2 * 40= 8

5r + 8 = -12Subtract 8 from each side:5r = -20Divide each side by 5:r = -4

5r = 25 is a linear equation in one variable, r. The solution is r = 5.

13r+10=5r-46 r= r = -7
