The number of a is more than twice that of B. 4. The product of two natural numbers a and B is 96. What are the numbers a and B? (using equation and proportion)

The number of a is more than twice that of B. 4. The product of two natural numbers a and B is 96. What are the numbers a and B? (using equation and proportion)


A is 6, B is 16. Let B be x, then a is 2x + 4, countable one variable quadratic equation x (2x + 4) = 962x & # 178; + 4x = 962 (X & # 178; + 2x) = 96x & # 178; + 2x = 48x & # 178; + 2x + 1 = 48 + 1 (x + 1) & # 178; = 49x + 1 = ± 7, so X1 = 6, X2 = - 8, so a is 6 or - 8



If the sum of a and B is 5, the product is 6, and a is x, then the equation is


Let a be x, then B be 5-x, then there is
x(5-x)=6
The solution is x = 2 or 3



6 / 7 of a number is more than 2 / 3 of it. 8 what's the number? (solve the equation)


Let this number be X
Then x * (6 / 7) - x * (2 / 3) = 8
The solution is x = 42



The number a is 8 / 3, which is equivalent to 5 / 7 and 1 / 5 of the number B. what's the number B? The solution of the equation should be fast


B number x
5/7x+1/5=8/3
5/7x=8/3-1/5
5/7x=37/15
x=259/75
