WHAT IS 5X-16?
21
Translate this word problem as a system of equations and then solve using substitution Find two numbers whose sum is 58 and whose difference is 16?
Suppose the two numbers are x and y. Then x + y = 58 and x - y = 16 The second equation gives x = 16 + y Substituting this value of x into the first equation gives (16 + y) + y = 58 or 2y + 16 = 58 or 2y = 42 which gives y = 21. Then x = 16 + y gives x = 16 + 21 = 37 So the soln is x = 37, y = 21
16 over 21 divided by 8 over 9?
To divide by a fraction, multiply by its reciprocal. In this instance, 16/21 / 8/9 is equal to 16/21 x 9/8 = 0.857142 recurring (that is, 0.857142857142...)
Two numbers have a product of 80 their sum is 21?
Let the two numbers be x and y. According to question, x * y = 80.....................(1) and x + y = 21.................................................(2) (1) implies that y=80/x......................................(3) Now, Substituting this value in equation (2) we get, x + 80/x=21 or x2 - 21x + 80=0. Solving this quadratic equation x=16 and x=5. If x=16, then (3) implies y=5 If x=5, then (3) implies y=16. Hence the two numbers are 16 and 5.
When the sum of two numbers is 21 When the larger number is subtracted from four times the smaller the difference is 4 what is the two numbers?
