i got x = 1.35 12x+18=41-5x +5x 17x+18=41 -18 17x=23 /17 x=1.35
3x+14 = 23 so 3x = 9 and so x = 9/3 = 3
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
y = 2x + 15 y = 4x + 7 Substitute the value of y from the first equation into the second: 2x + 15 = 4x + 7 Subtract 2x from both sides: 15 = 2x + 7 Subtract 7 from both sides: 8 = 2x Divide both sides by 2: 4 = x. Replace x by its value, 4, in the first equation: y = 2*4 + 15 = 8 + 15 = 23 So the solution is (x, y) = (4, 23)
Assuming that by expressing that equation as a question you're looking to solve for x: x2 - 4x - 29 = -10 x2 - 4x + 4 = 23 (x - 2)2 = 23 x - 2 = ± √23 x = 2 ± √23
P=5.75. You know 4P is 23 because you subtract 3 from it and are left with 20. Just divide 23 by 4 to get the value of each "p".
A = w*l so 184 = w*23 or w = 184/23 = 8 cm

X = 11.5
It is an equation and the value of g is 2.

It's a simple linear equation in 'y'.If you want to know what value of 'y' makes it true,you can find it like this:23 + Y = 14Subtract 23 from each side of the equation:Y = 14 - 23Y = -9
X = 88/7 = 12.571 (3dp)
If you mean what is the value of the width when the Area = 184 square cm and the length is 23 cm. Then the value of the width is: 184/23 = 8 cm Check: 8 times 23 = 184 square cm
okay wikianswers messed up the question. H0: M=23; H1: M not 23; n=50; x-bar = 21.25; standard deviation = 5. please help!
2x+3=23 minus 3 from both sides 2x=23-3 so we get 2x=20 divide both sides by 2 to get the value of x x=10
25x = 11 so x = 0.44
