Rhonda added 140 to one third of a number for a result of 216.What is the number?

unknown values: x

equation: 1/3 * x + 140 = 216

answer: 228

Find the five digit number in which the first two digits are the square of the third digit and the last two digits are the square of the digit that is one less than the third digit. The sum of all the digits is 22.

unknown values: m

equation: m = 10000*x + 1000*y + 100*z + 10*a + b

equation: 10*x + y = z^2

equation: 10*a + b = (z - 1)^2

equation: x + y + z + a + b = 22

answer: 36625

The units digit of a two-digit number is one-third the tens digit. When the digits are reversed, the new number is two more than four times the tens digit. Find the original number.

unknown values: m

equation: 10*x + y = m

equation: y = 1/3 * x

equation: 10*y + x = 4*x + 2

answer: 62

What is the number? the sum of the digits is 8. The product is 12. The number is between 30 and 90.

unknown values: m

equation: m = 10*x + y

equation: x + y = 8

equation: xy = 12

equation: x >30

equation: x

< 90 answer: 62 If y= 4(2x-9)+25. what is the value of y when x=25? unknown values: y equation: y= 4(2*x-9)+25 equation: x = 25 answer: 189 If the difference of a number and 5 is tripled, the result is 1/9. Find the number. unknown values: x equation: (x - 5) * 3 = 1/9 answer: 136/27 | 5.037 The units digit of a two-digit number is 5 more than the tens digit. If the digits are reversed and the new number is divided by the original, the quotient is 2 and the remainder is 7. What is the original number? unknown values: m equation: m = 10*x + y equation: y = x + 5 equation: (10*y + x) = 2*m + 7 answer: 38 what percent of 50 is 6? unknown values: x equation: x * 0.01 * 50 = 6 answer: 12 What percent of 80 is 50? unknown values: x equation: 0.01*x * 80 = 50 answer: 62.5 when 8 is subtracted from a certain number and the result is multiplied by 4, the answer is the same as when the number is added to 19. What's the answer? unknown values: x equation: (x - 8) * 4 = x + 19 answer: 17
