x+6y=9
-x+2y=-15

Answers

Answer 1

Answer:

8y = -6

Step-by-step explanation:

Simply add the equations as you would numbers.

The 'x's cancel each other out. The 'y's add together as normal numbers.

9 + (-15) = -6

Seating reads 1/12 part of a book in a day. If there are 360 pages in a book, how many pages does swati read in a day?

Answers

Given:

Total number of pages in a book = 360 pages

Fraction of pages Swati reads = [tex]\frac{1}{12}[/tex]

To find:

Number of pages Swati reads in a day

Steps:

Since we know the fraction of pages Swati reads each day, we can multiply the fraction with the total pages to find the number of pages read each day.

[tex]=360 * \frac{1}{12}[/tex]

[tex]= \frac{360 * 1}{12}[/tex]

[tex]=\frac{360}{12}[/tex]

[tex]=\frac{180}{6}[/tex]

[tex]=\frac{90}{3}[/tex]

[tex]=\frac{30}{1}[/tex]

= 30

Therefore, Swati reads 30 pages of the 360 pages per day.

A rectangular room has an area of 12 m².the length of the room is 4m. what is the width of the room?​

Answers

Answer:

3

Step-by-step explanation:

area of rectangle = length × width

so the the given area is 12

area of rectangle is 12 = 4 × width

so when we multiply 4 × 3 we get 12

and the final answer is ...

area of rectangle = length × width

4× 3 = 12

Answers

5x + 3 is a linear equation in one variable

solving system by substitution

Answers

Answer:

The solution of this system is (9, 2).

Step-by-step explanation:

Substitute x - 7 for 'y' in the first equation.  We get:

x - 3(x - 7) = 3           Doing this temporarily eliminates the variable 'y'.

Now perform the indicated multiplication, and then combine like terms:

x - 3x + 21 = 3, or

-2x = -18

so that x = 9.  Substituting 9 for x in the second equation, we get:

y = 9 - 7, or y = 2.  

The solution of this system is (9, 2).

Solve for j

-1/3 = j/4 - 10/3

Answers

Answer: J=12


Explanation: To make this equation easier to solve, you can make everything a whole number (a.k.a. Remove the fractions). To do so, you can multiply everything in this equation by the Least Common Multiple (LCM) of all the denominators, which is 12. The equation now becomes:

-4=3J-40

Then, solve it using normal algebra:

-4=3J-40
36=3J
J=12

Much easier, right?!

What is the length of Line segment A C?

Answers

Answer:

12

Step-by-step explanation:

The triangles are similar because they have the same angles.

Make a proportion to solve for AC which we will substitute with variable x.

AM = MB = 4

AB = AM + MB = 8

BN = NC = 3

BC = BN + NC = 6

big triangle sides: 8, 6, x

small triangle sides: 4, 3, 6

now we can write proportion.

8/4 = x/6

x = 12

AC = 12

Answer:

P = 11 4/5

Step-by-step explanation:

Let L = 2 1/2 and w = 3 2/5

[tex]P=2(2\frac{1}{2})+2(3\frac{2}{5})\\\\P=5+6\frac{4}{5}\\\\P=11\frac{4}{5}[/tex]

Answer:  11

The perimeter as a mixed number is P = 11 & 4/5, but it seems like your teacher only wants the whole part of the answer. So you'll just type 11.

============================================================

Work Shown:

1/2 = 0.5

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

This shows that L = 2.5 ft

Similarly, W = 3.4 ft because 3+2/5 = 3+0.4 = 3.4

-----------------

Plug those L and W values into the perimeter formula

P = 2L + 2W

P = 2*2.5 + 2*3.4

P = 5 + 6.8

P = 11.8

now convert back to a mixed number

11.8 = 11 + 0.8

11.8 = 11 + 8/10

11.8 = 11 + 4/5

11.8 = 11 & 4/5

The perimeter is 11 & 4/5 ft. In other words, the perimeter is 11 whole feet plus an additional 4/5 of a foot.

Your teacher seems to only want the whole part of the answer, assuming they only want the stuff in the box indicated with a question mark. If that's the case, then you'll type 11 into the box to write the final answer.

What is the probability of getting 2 blues?
(hegarty maths))

Answers

Answer:

The probability of getting 2 blues is 25/121.

Step-by-step explanation:

There are 6 + 5 marbles in total, 11 marbles.

The chances of picking a blue marble is 5/11.

Since you replace the marble you drew, the chances each draw remain 5/11

You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11.

5/11 * 5/11 = 25/121

The probability of getting 2 blues is 25/121.

convert the decimal number 356 to a Quinary number

Answers

Answer : Yes the answer to your question is 2411.

Explanation : how I got the answer

To convert decimal number 356.625, we convert its integer and fraction part individually and then add them to get the equivalent quinary number, as below:

To convert integer 356 to quinary, follow these steps:

Divide 356 by 5 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent quinary number.

356 / 5 = 71 with remainder 1

71 / 5 = 14 with remainder 1

14 / 5 = 2 with remainder 4

2 / 5 = 0 with remainder 2

Here is the answer to 356 decimal to quinary number:

Answers

Answer:

[tex]a_{n}[/tex] = 90 - 3n

Step-by-step explanation:

There is a common difference between consecutive terms, that is

84 - 87 = 81 - 84 = - 3

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 87 and d = - 3 , then

[tex]a_{n}[/tex] = 87 - 3(n - 1) = 87 - 3n + 3 = 90 - 3n
