A number multiplied by three equals 21. Find the number. Let x the number.?
If: 3x = 21 then x = 7
If y equals 3x and 3x equals 12 then what does y equals?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
What is 3x equals 3x?
3x-3x equal = 0
What multiplied by what equals 40?
1 multiplied by 40 equals 40.
What is the answer to 3x times the quantity 12x plus 9?
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
What does 3 multiplied by x equals 20?
If 3x=20, then x=20/3 or approximately 6.67
Does 3x multiplied by 2x equal 5x?
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
What does x stand for in the problem 3x equals 96-75?
In 3x = 96 - 75 the "x" stands for the number which, when multiplied by 3, equals the difference between 96 and 75. 96 - 75 = 21 If 3x = 21 then x = 21 divided by 3, or 7
If y equals 3x and 3x equals 12 what does y equal?
y = 12. It's the transitive property. y = 12 = 3x.
What is the slope to 3x plus 4y equals 12?
3x + 4y = 12 Subtract 3x from each side 4y = 12 - 3x Divide by 4 on each side y = 3 - .75x The slope is what is multiplied by "x" or -.75
A number multiplied by three equals 21. Find the number. Let x the number.?
If: 3x = 21 then x = 7
What number multiplied by 3 equals 70?
3x = 70 70/3 = x Therefore, x = 23.3 recurring (that is, 23.3333..)
How do you factorize 9 multiplied by x square plus 24 multiplied by x and y plus 16 multiplied by y square?
9x2 + 24xy + 16y2 = 9x2 + 12xy + 12xy + 16y2 = 3x(3x + 4y) + 4y(3x + 4y) = (3x + 4y)*(3x + 4y) = (3x + 4y)2
1 divided by 3x plus 6 equals 9?
1/3x + 6 = 9 Restating the problem x + 18 = 27 I multiplied by 3 x = 9 I subtracted 18 from 27
How do you solve 5x plus 3x?
There is NO solution, because there is NO equals sign. However, 5x + 3x add to 8x (simplified) Remember in Algebra 5x means '5' multiplied to 'x' and '3' multiplied to 'x'. The multiplication sign is never shown in algebra.
What is 3x 3x 3x 3x 3x in exponential from?
3x^5 If these are 5 of 3x multiplied together the it must be (3x)^5 =3^5 times x^5
6x plus 4-3x?
To solve the equation 6x plus 4-3x,first subtract 3x from 4 which leaves you with 1x. The equation now reads 6x plus 1x, which equals 7x. --- Actually, to simplify this, we have to keep the numbers multiplied with the variables from the plain numbers. The equation based on the question it this: 6X + 4 - 3X So there is a +6X a -3x and a +4. So we simplify by consolidating the numbers multiplied with the Xs. So 6X - 3X is 3X. So we have 3x + 4. There is no way to solve this since we have only part of it and no equal sign.
