Eighty, decreased by three times a number, is the same as five times the number, increased by eight.?

80 - 3x = 5x + 8\n80 - 8 = 5x + 3x\n72 = 8x \n9 = x\n\nWhat's your age anyway ?\n\nStrategy for solving an algebra problem.\n\n1.group numbers that contain the unknown variables (x in this case) into the same side of the equation (right hand side or left hand side, whichever you prefer) and don't forget to change the sign of the unknown variable if you move it across the equal sign.\n2. group the constant together ( without variable x or whatever variable in your problem)\n3. do the mathematical operation needed on each side to simplify the equation.\n4. Divide each side with the number before the variable. (8x = 72 , divide by 8 on each side).\n5. That's the answer.

10,7,8,4,9,8,25=4,7,8,8,9,10,25 if you put them in order from least to greatest, eliminate the numbers like ths: 7,8,8,9,10       \n            8,8,9\n              8\n          so its 8

two times of 'x' if increaed by four is equal to 4/5th of three times of 'x' after lowering by 5

The first three digits are actually multiplied by (80 x 250) = 20000. And you are adding 250 which you have subtracted latter.\n\nIn effect two times the first three digits followed by four zeros. You are adding two times the four digits so you get two times the original number. Dividing it by 2 u get the original value.\n\nYou can do this with 40 and 500, 20 and 1000, 10 and 2000 etc.

500 if the division is for all four numbers \nor \n800 if the division is for four only.

5 becuuse 45 = 5 * 9\nand 800 = 5 *160\n9 and 160 are coprimes

All the information you need is there - you just need to convert the information into an equation.\n"Difference" means subtract, right?\n"5 times a number" is 5 multiplied times an unknown number, which is usually shown as an "X".\n"4" is given.\n"is" means "=".\n\nPut it all together:\n\n5X - 4 = 16\n\nNext step is to solve for "X" by getting all of the known information on the right side of the "=" sign, so:\n\nadd "4" to each side of the equation: 5X - 4 + 4 = 16 + 4 so that 5X = 20\n\nNow divide each side of the equation by "5":  5X/5 = 20/5 so that\nX = 4

8/(3-(8/3))\n\n3-8/3 = 1/3\n\n8/ (1/3) is the same as 8*3 which is 24.

8= 2^3\n45= 3^2 times 5\n50=5^2 times 2\n150= 2 times 3 times 5^2\n\nhope thats what u need

Cross-multiply.  3 times 30 = 90, divided by 8 = 11.25

7/8 divided by .25 is the same as multiplying by 4. \n7/8 X 4 = 28/8 = 3 4/8 = 3 1/2

The answer is 72.  You multiply the three numbers together.

I think you're talking about "average," so you add up the numbers and divide by how many numbers you've added.\n\nthe average of 5, 6, and 7\nis 5+6+7 divided by 3\nso it's 18/3 = 6\n\nhope that helps, sorry if I'm way off

8 = 2^3\n.125 = 1/8 = 8^(-1) = 2^(-3)\n8^x = .125\n(2^3)^x = 2^(-3)\n2^(3x) = 2^(-3)\nWhen the bases are the same, then the exponents are the same.\n3x = -3\nx = -1

[8+(2*4)]*3 =48 =16*3=30+18=48, just this first expression none of the others
