Answer: 36 - 100%

43 - x  %

Step-by-step explanation 36 - 100%

43 - x  %

we multiply by cross ->  36 * x = 100 / 43  

we should remove '100%' from new value, because we find only increase.. no new value in percent.

x + 100 = (43 * 100)/36  

x =  4300/36 - 100

x = 119+ 16/36 -100

x = 19 +4/9

Answer:

  3

Step-by-step explanation:

Let x represent the number. The problem statement tells you ...

2/3(3x +6) = 10

  2x +4 = 10 . . . . . . use the distributive property

  x +2 = 5 . . . . . . . . divide by 2

  x = 3 . . . . . . . . . . .subtract 3

The number is 3.

__

Comment on the solution

The above shows an "alternative" solution method. The more usual way this might be done is ...

  2(3x +6) = 30 . . . . . multiply by 3 to clear fractions

  6x +12 = 30 . . . . . . . eliminate parentheses

  6x = 18 . . . . . . . . . . . subtract 12

  x = 3 . . . . . . . . . . . . divide by 6

Answer:

x=3

Step-by-step explanation:

Write the equation first, 2/3(3x+6)=10

Distribute 2,  2(3x+6)/2

Which equals 6x+12/3=10

Then multiply 3 from both sides 6x+12=30

Subtract 12

6x=18

Divide 6 from both sides

x=3

Answer: C.

Explanation: X= -7

You nearly have the right equation, but you should use t instead of x. Other than that, everything looks perfect.

Answer:

A library contains only paperback and hardback books. If the ratio of paperback books to the total number of books is 3 to 5, the true statement is:

The ratio of paperback books to hardback books is 3 to 2.

Step-by-step explanation:

The number of books in the library = 5

The number of paperback books in the library = 3

Therefore, the number of hardback books in the library = 2 (5 - 3)

Then, the relationship between the paperback books and the hardback books in the library can be expressed as a ratio of 3:2.  This still gives the sum of the ratios as 5, which is the total number of books in the library, including paperback and hardback books.

Answer:

9.2

Step-by-step explanation:

102/11

i would take him 9.2 months to pay back

Ideally, he will repay the whole amount of $102 in 10 months where he will pay $11 for first 9 months and $3 in the 10th month.

Given information:

Keith borrowed $102 from his dad, and he is paying him back $11 each month.

So, Keith will pay back his dad an amount of $11 every month till the debt is cleared.

Now, the number of months required by Keith to repay will be calculated as,

[tex]\dfrac{102}{11}=9+\dfrac{3}{11}[/tex]

Now, Keith will need [tex]9+\dfrac{3}{11}[/tex] months to completely repay his debt.

Fraction of month is not an option for repayment. So, he will pay $11 regularly for 9 months which will be $99 in the repayment, and the remaining $3 will be paid by him in the 10th month.

Therefore, ideally, he will repay the whole amount of $102 in 10 months where he will pay $11 for first 9 months and $3 in the 10th month.

Answer:

multiply by 25 also.

Step-by-step explanation:

If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.

If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.

Answer:

75 number of quarters

150 number of nickels

35 number of dimes

Step-by-step explanation:

Let x, y and z be the amount of quarters, nickel and dimes respectively.

​he learns that he has 260 coins, thus;

x + y + z = 260 - - - (1)

Now, we are told that he has twice as many nickels as quarters.

Thus, number of nickels = 2x

y = 2x - - - (2)

From online research, we have the following cost;

1 quarter = $0.25

1 nickel = $0.05

1 dime = $0.1

Total cost is $29.75. Therefore;

0.25x + 0.05y + 0.1z = 29.75 - - - (3)

Put 2x for y in eq (1) and eq (3) to get;

x + 2x + z = 260

3x + z = 260 - - - (eq 4)

0.25x + 0.05(2x) + 0.1z = 29.75

0.25x + 0.10x + 0.1z = 29.75

0.35x + 0.1z = 29.75 - - - (eq 5)

From eq(4), z = 260 - 3x

Thus;

0.35x + 0.1(260 - 3x) = 29.75

0.35x + 26 - 0.3x = 29.75

0.05x = 29.75 - 26

0.05x = 3.75

x = 3.75/0.05

x = 75

So, z = 260 - 3(75)

z = 260 - 225

z = 35

Since y = 2x,

Then,y = 2(75) = 150

Thus,we have;

75 number of quarters

150 number of nickels

35 number of dimes
