Solve for x: 3(x+1)=5(x-2)+7

Mathematics
1 answer:
mojhsa [17]2 years ago
7 0

Answer:

x = 3

Step-by-step explanation:

3 ( x + 1 ) = 5 ( x- 2 ) + 7

Expand

3 x + 3 = 5 x  - 10 + 7

Minus 5 x from both sides

- 2 x + 3 = - 10 + 7

Minus 3 from both sides

- 2 x = - 10 + 4

Simplify

- 2 x = - 6

Divide both sides by - 2

x = 3

Urgent please ans this​
Rama09 [41]

Answer:

x=6

Step-by-step explanation:

Remember, the formula for area is the length times the width. So, if we know the width is 3, and we know the total area is 24, all we need to do is divide 24 by 3 to get 8. 8 is the split up side, the one that is x + 2. To find x, simply subtract 2 from 8. 8 - 2=6.

24/3=8

8-2=6

Find the sum that amounts to Rs 9,144 in 3 years at 9% per year simple interest.​
Hunter-Best [27]

Given:

Amount = Rs. 9,144

Time = 3 years.

Rate of simple interest = 9%

To find:

The principal value.

Solution:

The formula for simple interest is:

I=\dfrac{P\times r\times t}{100}

Where, P is principal, r is the simple rate of interest, and t is the number of years.

Putting r=9,t=3 in the above formula, we get

I=\dfrac{P\times 9\times 3}{100}

I=\dfrac{27P}{100}

I=0.27P

We know that,

\text{Amount}=\text{Principal + Interest}

9144=P+0.27P

9144=1.27P

Divide both sides by 1.27, we get

\dfrac{9144}{1.27}=P

7200=P

Therefore, the principal value is Rs. 7200.
