how do you solve 18p-2p+6=9+5
0.3x - 0.2y = 4 (or you can multiply by 10 in order to work with whole numbers) 0.2x - 0.3y = 5/23 3x - 2y = 40 2x -3y = 50/23 2(3x) - 2(2y)= 2(40) -3(2x) - (-3)(3y) = (-3)(50/23) 6x - 4y = 80 -6x +9y = -150/23 6x - 6x - 4y + 9y = 80 - 150/23 5y = 1690/23 y = (1690/23)/(5) y = (1690/23)(1/5) y = 338/23 2x - 3y = 50/23 2(338/23) - 3y = 50/23 676/23 -3y = 50/23 -3y = -676/23 + 60/23 -3y = -616/23 y = (-616/23)/(-3) y = (-616/23)(-1/3) y = 616/69
Solve the equation below for x. If your answer is not a whole number, enter it as a fraction in lowest terms, using the slash mark ( / ) as the fraction bar.3x + 5 = 6x + 23x=-6
1/5
11X - 23 = 7X + 5 subtract 7X from both sides 11X - 7X - 23 = 7X - 7X + 5 4X - 23 = 5 add 23 to both sides 4X - 23 + 23 = 5 + 23 4X = 28 divide both sides integers by 4 (4/4)X = 28/4 X = 7 --------------------check in original equation 11(7) - 23 = 7(7) + 5 77 - 23 = 49 + 5 54 = 54 checks
If A is a variable that you are solving for and the problem is A + 5 = 23 then you subtract 5 from both sides to solve for A... A + 5 - 5 = 23 - 5 Simplify... A = 18
No. 5 can only go into values that end in 0 or 5, so it cannot go into 424 evenly.

Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840
23 x 5 = 115
84.8 = 848/10 = 424/5

3X + 5 = 23subtract 5 from each side3X + 5 - 5 = 23 - 53X = 18divide both sides integers by 3(3/3)X = 18/3X = 6=======check by inserting 6 where X is in original equation3(6) + 5 = 2318 + 5 = 2323 = 23========checks
Question:Convert 23°C toFahrenheitConversion Formula: Tf = (9/5)Tc+32Using the formula, plug in the temperature forTcand solve forTf. Tf= (9/5)Tc+32Tf= (9/5)(23)+32 = 41.4 + 32 = 73.4°FSo 23°C is equal to 73.4°F.
