Answer 1

Answer:

Answer:

The answer is 88%

Step-by-step explanation:

To find a percentage, just divide the top number by the bottom. 22 divided by 25 is 0.88 which means 22 out of 25 is 88%.

Another way to do it is to multiply both 22 and 25 by 4. The denominator will now equal 100 so now the top number will be the percentage. 22*4 is also 88.

Hope this helped.

Hello! :)

1/2x + 5 = 15

1/5x + 5 - 5 = 15 - 5 Subtract 5 from both sides

1/2x = 10

2 * (1/2x) = (2) * (10) Multiply both of the sides by 2

x = 20

Answers

Answer for Question (1):

The system of equations: x+3y=6

2x-y=10

Solve the first equation x+3y=6 for y:

Subtracting x on both sides,

x+3y-x=6-x

3y=6-x

Now dividing 3 on both sides, we get

y=2-x/3 = negative one third x + 2

Thus y= negative one third of x +2

Answer for question (2):

The system of equation :

5x-3y=-3 --> (1)

2x-6y=-6 -->(2)

Multiply equation (1) by 2, we get 10x-6y=6.

Subtracting (1) by (2), we get 8x=0 implies x=0.

Plug in x=0 in equation (1), 0-3y=-3

Dividing -3 on both sides,

y=-3/-3=1

So the solution of y is 1.

Answer for Question (3):

System of equation:

7x-2y=-3 (1)

14x+y=14 (2)

Multiply (2) by 2,

28x+2y=28 (3)

Adding (1) and (3), we get 35x=25

Now dividing 35 on both sides, x=25/35=5/7.

Plug in x=5/7 in equation (1), we get 5-2y=-3

-2y=-3-5

-2y=-8

Dividing -2 on both sides,

y=4

Thus the solution of this system of equation as (5/7,4).

Answer for question (4):

x + 3y = 9 ---> (1)

3x − 3y = −13 ---> (2)

Adding equation (1) and (2), we get

4x=-4

Dividing 4 on both sides,

x=-1

Plug in x=-1 in equation (1), we get

-1+3y=9

Adding 1 on both sides,

3y=9+1=10

Now dividing 3 on both sides,

y=10/3.

so the solution is (-1,10/3).

Answer for question (5):

System of equation is 4x − y = 3 (1)

7x − 9y = −2 (2)

consider the first equation 4x-y=3

Adding y on both sides, 4x=3+y

subtracting 3 on both sides, we get y=4x-3

Substitute y=4x-3 in equation (2),

7x-9(4x-3)=-2

7x-36x+27=-2

Combine the like terms,

-29x+27=2

Adding 27 on both sides,

-29x=-29

dividing -29 on both sides,

x=1

Plug in x=1 in y=4x-3,

y=4(1)-3=1

Then the solution is (1,1).

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The best way to find this out is to find the total number, minus the remained.

In this case,

196 - 4 = 192.

As We have got to put the pencils into 8 boxes, we have to divide 192 by 8,

192 / 8 = 24.

Also, If x represents the number of pencils per box, the equation

8x + 4 = 196.

Therefore, Soni can put 24 pencils can be put into each box with four pencils remaining.

Joe solved this linear system correctly.6x+3y=6

y=−2x+2

These are the last two steps of his work.

6x−6x+6=6

6=6

Which statement about this linear system must be true?

a) x must equal 6

b) y must equal 6

c) there is no solution to this system

d) there are infinitely many solutions to this system

Answers

There are infinitely many solutions because the first two equations are actually the same just arranged differently so there's not enough information to know what x or y are in other words they could be anything.
