What is the answer to 2x+4y=16:4y=12

Mathematics
1 answer:
allsm [11]2 years ago
8 0

Answer:

Here,

2x + 4y = 16....eqn \: i \\ 4y = 12....eqn \: ii

substituting the value of 4y in eqn i fron eqn ii

so eqn i becomes

2x + 12 = 16 \\ 2x = 4 \\ x = 2

So

y = 12 \div 4 = 3

Thus,

x = 2 \: and \: y = 3

...hope this helps:)

Answer:

3x7 • (4x2 - 5x + 3)

Step-by-step explanation:

End of step 1- (3 • (x7)) • ((22x2 -  5x) +  3)

End step 2- 3x7 • (4x2 - 5x + 3)

Step 3-Trying to factor by splitting the middle term

3.1     Factoring  4x2-5x+3

The first term is,  4x2  its coefficient is  4 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  +3

Step-1 : Multiply the coefficient of the first term by the constant   4 • 3 = 12

Step-2 : Find two factors of  12  whose sum equals the coefficient of the middle term, which is   -5 .

     -12    +    -1    =    -13

     -6    +    -2    =    -8

     -4    +    -3    =    -7

     -3    +    -4    =    -7

     -2    +    -6    =    -8

     -1    +    -12    =    -13

     1    +    12    =    13

     2    +    6    =    8

     3    +    4    =    7

     4    +    3    =    7

     6    +    2    =    8

     12    +    1    =    13

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 3x7 • (4x2 - 5x + 3)

gavmur [86]

Answer:

Rs. 1186 is the required answer.

Step by step answer:

Given:

Principle (P)=$1500

Rate of Interest (R)= 6%

Time period (T)=10 years

Compound Interest (CI)=P((1+6/100)^T-1)

=1500((1+6/100)^10-1)

= Rs. 1186 (approximately)
