Determine the solution.
2x+y=4
4x-3y=7

Answers

Answer 1

Answer:

The answer is: (x , y) = (19/10 , 1/5)

Step-by-step explanation:

Solve the equation for y-

y = 4 - 2x

4x - 3y = 7

Substitute the given value of y into the equation-

4 x - 3 ( 4 - 2x ) = 7

Solve the equation for x-

x = 19/10

Substitute the given value of x into the equation y = 4 - 2x-

y= 4 - 2 * 19/10

Solve the equation for y-

y = 1/5

The possible solution of the system is the ordered pair ( x , y )-

( x , y ) = ( 19/10 , 1/5)

Check if the given ordered pair is the solution of the system of equations-

{2 * 19/10 + 1/5 =4

4 * 19/10 - 3*1/5 =7}

Simplify the equalities-

4 = 4

7 = 7

Since all equalities are proven true the ordered pair is the solution of the system-

( x , y) = (19/10, 1/5)

FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)

Hope this helps you!! :) <333

I thought of a number, multiplied it by 2 1/2, divided the result by 1 1/5, subtracted 7/18 from it, and got 1 5/6. What was my number?

Answers

1 and 1/15

Work backwards, so add 7/18 to 1 5/6 first (I'm gonna add them in improper fraction form to make it easier) and you get 40/18 which is 20/9
Then multiply by 1 1/5 (or 6/5) to get 120/45 which simplifies to 8/3
Then divide by 2 1/2, or 5/2, which means you multiply by the reciprocal (2/5)
8/3 times 2/5 equals 16/15 or 1 1/15

Answer:

1 1/15

Answers

Answer:

e(1) = 2,   e(n+1) = e(n-1)*e(n)  for n > 1f(1) = 1,   f(n) = n*f(n-1)  for n > 1

Step-by-step explanation:

Given sequences e) 2, 3, 6, 18, 108, 1944, ... f) 1, 2, 6, 24, ...To findRecursive formula for the general termSolution

We can observe that

e) 2*3 = 6, 3*6= 18, 18*6= 108, 108*18 = 1944f) 1*2 = 2, 2*3= 6, 6*4= 24

We can put it in general terms as

e(1) = 2,  and e(n+1) = e(n)*e(n-1)  for n > 1f(1) = 1,  and f(n) = f(n-1)*n  for n > 1

What is 1/5 as a percentage and decimal?

Answers

Answer:

1/5 as a percentage:

1/1*20

20/1

20%

1/5 as decimal:

(JUST SIMPLY DIVIDE 1/5)

0.2

Answer:

20% and 0.20

Step-by-step explanation:

Let's say 5/5 = 100, so then in order to convert 1/5 into a percentage, all you have to do is divide 100 by 5, and that will be your percentage:

100 / 5 = 20

So, 1/5 = 20%

Now, as a decimal its basically the same thing, but instead of thinking of it as 100, you think of it as 1.00, and then your decimal form of 1/5 will be 0.20

If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks.
