if five times a number added to 4 is divided by the number plus 6 the result is nine halves, Find The Number
1 answer:
Answer:
8/13
Step-by-step explanation:
Let the number be x
if five times a number added to 4 is divided by the number plus 6 the result is nine halves
five times the number = 5x five times a number added to 4 = 5x+4 five times a number added to 4 is divided by the number = (5x+4)/x five times a number added to 4 is divided by the number plus 6 = (5x+4)/x + 6 nive halves = 9*(1/2) five times a number added to 4 is divided by the number plus 6 the result is nine halves
(5x+4)/x + 6 = 9(1/2)
=>(5x+4)/x + 6 -6 = 9(1/2) -6 = 9/2-6 = (9-6*2)/2 = -3/2
=>(5x+4)= -3/2 *x= -3x/2
=>2(5x+4) = -3x
=> 10x +8 = -3x
=> 10x+3x = 8
=> 13x = 8
=> x = 8/13
Thus, the number is 8/13

Answer:
(x + 6)(x + 8)
Step-by-step explanation:
Consider the factors of the constant term (48 ) which sum to give the coefficient of the x- term (14 )
The factors are + 6 and + 8
since 6 × 8 = 48 and 6 + 8 = 14
x² + 14x + 48 = (x + 6)(x + 8) ← in factored form
