If 2 is to 7 as 12 is to?
2:7::12:x Divide the '12' by '2' and multiply by '7' Hence 12 x 7 / 2 6 x 7 = 42 Hence 2:7::12:42
What 2 numbers multiply to the value of 35 and add to the value of 12?
7 x 5 = 35 7 + 5 = 12
Solve for x in x plus 1 over x equals -7 over x - 12?
You have : -------------- ( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 ) Multiply both sides by ( x ) ( x - 12 ) and get : ( x + 1 ) ( x - 12 ) = ( -7 ) ( x ) x^2 - 12x + x - 12 = -7x x^2 - 4x - 12 = 0 Factor the above : ( x - 6 ) ( x + 2 ) = 0 There are two roots : x = 6 <------------------ x = -2 <---------------
What is 7 percent of 12?
You would solve this like an algebratic equation:12 100---- = -----7 xThen you'd cross multiply..12(x) = 100(7)12x=700Then you'd divide..12x=700--- -----12 12x=58.3(The three is repeating)
Multiply 7 8 2 3?
If that's 7/8 x 2/3, the answer is 14/24 or 7/12
If 2 is to 7 as 12 is to?
2:7::12:x Divide the '12' by '2' and multiply by '7' Hence 12 x 7 / 2 6 x 7 = 42 Hence 2:7::12:42
How do you solve 12 over variable equals 6 over 7?
Let the variable be x: 12/x = 6/7 Multiply both sides by x: 12 = 6x/7 Multiply both sides by 7: 84 = 6x Divide both sides by 6 to find the value of x: x = 14
What is two thirds divided by seven twelfths?
7/12 divided by 2/3 equal 7/12 times 3/2 (We invert and multiply when dividing fractions.) 7/12 times 3/2 equals 7 x 3 / 12 x 2 (Multiply the numerators together and multiply the denominators together.) 7 x 3 / 12 x 2 = 21 / 24 Now find the lowest common denominator. 21 / 24 = 7 / 8
What 2 numbers multiply to the value of 35 and add to the value of 12?
7 x 5 = 35 7 + 5 = 12
What two numbers can you multiply together to equal 12 and add together to equal 7?
19
What is the product of 3 X 4 X 7?
Break it down, solve 3*4 first, then multiply that by 7.3*4=12 12*7=84
Find a solution of 1overx-1 plus 1overx equals 7over12?
Do you mean 1/x-1+1/x = 7/12? If so then the solution is: 2/x-1 = 7/12 Multiply all terms by 12: 24/x-12 = 7 Multiply all terms by x: 24-12x = 7x 24 = 7x+12x 24 = 19x Solution: x = 24/19
An 8 by 12 photo is reduced to 70 what are the demensions of the reduced photo?
I assume you mean it was reduced to 70% of original 8 X 12. Multiply 8 X .7 to find new width, and multiply 12 X .7 to find new length. New dimensions are 5.6 X 8.4
Solve for x in x plus 1 over x equals -7 over x - 12?
You have : -------------- ( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 ) Multiply both sides by ( x ) ( x - 12 ) and get : ( x + 1 ) ( x - 12 ) = ( -7 ) ( x ) x^2 - 12x + x - 12 = -7x x^2 - 4x - 12 = 0 Factor the above : ( x - 6 ) ( x + 2 ) = 0 There are two roots : x = 6 <------------------ x = -2 <---------------
two equivalent fractions for seven over fifteen?
Multiply numerator and denominator by 2 to get an equivalent fraction: 7 x 2 15 x 2 = 14 30 Multiply numerator and denominator by 3 to get an equivalent fraction: 7 x 3 15 x 3 = 21 45 Multiply numerator and denominator by 4 to get an equivalent fraction: 7 x 4 15 x 4 = 28 60 Multiply numerator and denominator by 5 to get an equivalent fraction: 7 x 5 15 x 5 = 35 75 Multiply numerator and denominator by 6 to get an equivalent fraction: 7 x 6 15 x 6 = 42 90 Multiply numerator and denominator by 7 to get an equivalent fraction: 7 x 7 15 x 7 = 49 105 Multiply numerator and denominator by 8 to get an equivalent fraction: 7 x 8 15 x 8 = 56 120 Multiply numerator and denominator by 9 to get an equivalent fraction: 7 x 9 15 x 9 = 63 135 Multiply numerator and denominator by 10 to get an equivalent fraction: 7 x 10 15 x 10 = 70 150 Multiply numerator and denominator by 11 to get an equivalent fraction: 7 x 11 15 x 11 = 77 165 Multiply numerator and denominator by 12 to get an equivalent fraction: 7 x 12 15 x 12 = 84 180 Multiply numerator and denominator by 13 to get an equivalent fraction: 7 x 13 15 x 13 = 91 195 Multiply numerator and denominator by 14 to get an equivalent fraction: 7 x 14 15 x 14 = 98 210 Multiply numerator and denominator by 15 to get an equivalent fraction: 7 x 15 15 x 15 = 105 225

Solving fraction equations by multiplying?
Example: 2x/7 = 12 First, multiply the reciprocal of 2/7, which is 7/2, to both sides of the equation to isolate x. You should now have: x = 12 x 7/2 --> x= 6 x 7 --> x = 42 *simplify 12 x 7/2 by cancelling two from 12 and 2. I'm not sure if this is what you're asking for, but hopefully it helps.
