Nine bricks\n\nEight would leave you 3/8 inch short.

(x-7)(x-5)\nso x= +7, or +5

12\n\nbecause 1/7 is 4 and 4 times 3 is 12

x is age 5 years ago.  so x = 7.  age now is x + 5 = 12

Multiply the length by the width by the height.\n\nIn your case 7*7*7 = 343 cubic units*\n\n*Whatever units you used for example cm's - cm3\n\nHope this is want you were after.

(4)/(x+7) + (x+3)/(x+7)\n=(4 + (x+3))/(x+7)\n=(4 + x + 3)/(x+7)\n=( x +7)/(x+7)\n=1

a) (6x-7y)(6x+7y)\nb) y(4xy-7)\nc) (x-8)(x+3)

- 7 - 4x < 13\n\n-7 - 4x + 7 < 13 + 7\n\n- 4x < 20\n\n- 4x/- 4 > 20 /- 4\n\nx > - 5\n\nThe answer is x > - 5\n\n- - - - -s-

4x + 7 = -7\n4x = 14\nx = 14/4\nx = 7/2

12 and 7/8ths\n\nconvert the 1/2 to 4/8, the 3/4 to 6/8, add the fractions to get 15/8 which is 1 and 7/8, then add the whole numbers

Some folks seem to have forgotten this is a quadratic, and they have two (2) roots!\n\n(x - 7)^2 = 64\n\nx - 7 = ± 8 (take the square root of both sides)\n\nso \n\nx = 7 + 8 = 15 \n\nor \n\nx = 7 - 8 = -1\n\nyou could expand this out and use the quadratic equation to solve it as well:\n\nx^2 - 14x + 49 = 64\n\nx^2 -14x - 15 = 0  a = 1 b = -14  c = -15\n\nthe rest is left to the student as an exercise. :^)

Take the 4x and introduce it to 7. Then ask y if it is equal to the sum of 4x and 7 if they like each other. If 7 is in agreement, then 4x can ask y to lunch and the intercept will all work out at the gym. 7 can go home with the question mark. Simple!

first subtract 2x from both sides to get:\n\n-7=3x+7  \n\nthen add 7 to both sides to get:\n-14=3x\nx=-14/3 or -4 2/3

The actual question you should be asking is.  What is seven times six?  Answer:  42
710425
let it be x\n2x-7 = 43 ( 7 less than twice the number = 2x -7)\n2x = 50 (tranfer 7 to RHS)\nx = 25 (devide by 2)
