#9. Solve: 8x + 5 = 3x + 15 X = 4 x = 2 x = 20/11 x = 20

Jobisdone [24]

Answer:

x = 2

Step-by-step explanation:

8x + 5 = 3x + 15

8x - 3x + 5 = 3x - 3x + 15

5x + 5 = 15

5x + 5 - 5 = 15 - 5

5x = 10

5x / 5 = 10 / 5

x = 2

At what time the sum Rs. 5000 will be doubled at the interest of 10% per annum?

FromTheMoon [43]

Answer:

Time= $10$ years

Step-by-step explanation:

Let total time $=t$

Initial Amount $=5000$

Final Amount $=10000$

Total interest = Final Amount - Initial Amount

$=10000-5000\\=5000$

Simple Interest $=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years$

The tension t in a spring varies directly with the distance d the spring is stretched. If the

yarga [219]

Answer:

t = 21d

Step-by-step explanation:

Here tension and distance are denoted t by d and respectively. Since t varies directly with d , then the relation between t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting t = 42 and d= 2 into t = kd find the value of k . Therefore,

42= K (2)

$K=\frac{42}{2}$

K= 21

Thus the relationship is t = 21d
