x=5.1 because 5.5x+18.7=46.75 and you have to first subtract 18.7 from each side which leaves you with 5.5x=28.05 which you then need to divide both sides by 5.5 to get x alone. You can't divide by a decimal easily so you move the decimal of each over one spot so you now are dividing 280.5 by 55 which is 5.1 so x is equal to 5.1. You can also put 5.1 into the equation in place of x and solve it. If both sides turn out equal, then the answer is correct.

What is 20 plus x equals 55?
20 + x = 55x = 55 -20x= 35
What is 25X2 plus 55X plus 28?
so...50+55x+28??? then it would be 78+55x because you cant add them since they aren't like terms.
What is -5x plus 3x plus 8?
-5x^2 - 55x - 120
How do you solve 7 minus 5x equals 10 minus parenthesis6x plus 7parenthesis?
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x
What is the point of contact when the lines of 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0 intersect each other showing work?
If: 5x+7y+29 = 0 and 11x-3y-65 = 0 Then: 5x+7y = -29 and 11x-3y = 65 Multiply all terms in the 1st equation by 11 and all terms in the 2nd equation by 5 So: 55x+77y = -319 and 55x-15y = 325 Subtract the 1st equation from the 2nd equation: 92y = -644 => y = -7 Therefore by substitution the point of contact is at: (4, -7)
What is 20 plus x equals 55?
20 + x = 55x = 55 -20x= 35
What is 25X2 plus 55X plus 28?
so...50+55x+28??? then it would be 78+55x because you cant add them since they aren't like terms.
What does x mean in this equation -55x plus 6 plus 4 equals -191?
x is equivalent to 3.6545, having 45 repetetive. With this multuplied by 55 and added 10 (4 plus 6) equals -191
Solve for x 55x plus -3 equals 53x plus 7?
55x + (-3) = 53x + 7can be written as55x - 3 = 53x + 7subtract 53x from both sides2x - 3 = 7add three to both sides2x = 10divided both sides by 2x = 5
What is -5x plus 3x plus 8?
-5x^2 - 55x - 120
How do you solve 7 minus 5x equals 10 minus parenthesis6x plus 7parenthesis?
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x
Can you factor 6x2 plus 110x-970?
2(3x^2 + 55x - 485)
Factor x2 plus 55x-700?
x2 + 55x - 700 = (x + 20)(x + 35) 2x2x5x5x71,700=6992,350=3484,175=1715,140=1357,100=9310,70=6014,50=3620,35=1525,28=3If you were doing x^2+55x+700 then it would be factorable with 20 and 35 but with a negative in front of the 700 it is prime.
Factor the polynomial by grouping the terms together two at a time 66x3 - 36x2 plus 55x - 30?
66x^3 - 36x^2 = 6x^2(11x - 6) 55x - 30 = 5(11x - 6) 66x^3 - 36x^2 + 55x - 30 = (6x^2 + 5)(11x - 6)
How do you solve 3 over 5 plus 5x over 2 equals 8?
3/5 + 5x/2 = 8Multiply each term by 53 + 25x/2 = 40Multiply each term by 26 + 25x = 8025x = 80 - 625x = 74x = 74 / 25OR3/5 + 5x/2 = 85x/2 = 8 - 3/55x/2 = 40/5 - 3/55x/2 = 37/55x = 37/5 * 25x = 74/5x = 74/5 * 1/5x = 74/25
Reduce 3x plus 5 2x plus 1?
If you mean solve for X: 3x + 52x + 1 = 0 55x = -1 x = -0.02
What is the the point of intersection of the equations 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0?
1st equation: 5x +7y +29 = 0 or 5x +7y = -29 2nd equation: 11x -3y -65 = 0 or 11x -3y = 65 Times all terms in the 1st equation by 11: 55x +77y = -319 Times all terms in 2nd equation by 5: 55x -15y = 325 Subtract the 2nd equation from the 1st equation: 92y = -644 or y = -7 By means of substitution point of intersection is made at: (4, -7)
