What is the solution of the equation 8(3x+4)=2(12x-8)?

1 answer:

7 0

There is no solution because after you distribute, you have 24x in both sides. When moved to the other side, they cancel. Therefore, you are left with 24=-16 which isn’t true.

Can the numbers 24,32,40 be the lengths of three sides of a right triangle?

Naddika [18.5K]

Answer:

Yes

Step-by-step explanation:

using pythagorus theorum: a^{2} + b^{2} = c^{2}

24^{2} +32^{2} = 1024+576

= 1600

40^{2} = 1600

thus, it can be concluded that these lengths can be the sides of a right-angled triangle.

Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

= $\frac{9}{12} years$

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

$Interest = Principal \times Rate \times time$

$116.25=1550 \times r \times \frac{9}{12}$

$r= \frac{116.25 \times 12}{1550 \times 9}$

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%
