Answer:

a = 15

b = -10

Step-by-step explanation:

Here, we want to solve the system of linear equations

Firstly, let us multiply the first equation through by 10

2a - 5b = 100 ••••(i)

from the second equation;

a = 29 + b

Substitute this into i

2(29 + b) - 5b = 100

58 + 2b -5b = 100

-3b = 100-58

3b = 42

-b = 42/3

-b = 14

recall;

a - b = 29

a - (-14) = 29

a + 14 = 29

a = 29-14 = 15

Answer:

a = 15

b = - 14

Step-by-step explanation:

Solve the equation for a

a = 29 + b

Substitute the given value of a into the equation  [tex]\frac{a}{5}-\frac{b}{2}=10[/tex]

[tex]\frac{29+b}{5}- \frac{b}{2} =10[/tex]

Solve the equation for b

b = - 14

Substitute the given value of b into the equation a = 29 + b

a = 29 + (- 14)

Solve the equation for a

a = 15

The possible solution of the system is the ordered pair (a, b)

(a, b) = (15, -14)

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

[tex]\frac{15}{5} - \frac{-14}{2} = 10[/tex]

[tex]15-(-14) = 29[/tex]

Simplify the equalities

10 = 10

29 = 29

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

(a, b) = (15, -14)

Add all the fractions greater than 1/4 inches

The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.

Since the equivalent to 1 by 4 should be like  2/8, 3/12, 4/16 etc. Here the fractions that come after 1 by 4 so it should be more than 1 by 4. So now we have to determine the count and also the x in the column for the measurements so based on this, we can get 6.

Therefore, The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.

Algebraically solving the equation :

5x=2x+6

Take 2x from RHS to LHS .

5x - 2x = 6

3x = 6

Now divide both sides by 3 .

x = 6/3

Answer:

P = 73.1 m

Step-by-step explanation:

The length of a rectangle, l = 20.75 m

The width of a rectangle, b = 15.8 m

We need to find the perimeter of the garden. The formula for the perimeter of a rectangle is given by :

P = 2(l+b)

Substitue all the values,

P = 2(20.75+15.8)

P = 2(36.55)

P = 73.1 m

So, the perimeter of the garden is 73.1 m.

Step-by-step explanation:

So basically you take the last  three numbers. the middle 6 is over 5 so you round the first 6 to 7 and the rule for that is 5 or above round up 4 or below round down  

51668 to the nearest hundred is 51700

1. Identify the hundreds digit of the number.

2. Identify the next smallest place value.

3. We have to find out,is that digit greater than or equal to five!

4. Increase the hundred digit by 1 if greater or equal to 5 & decrease if less than 5. And every digit after it, becomes zero.

Given number is 51668

Hundreds digit number is 6.

Next smallest place value is 6, which is greater than 5.

Answer:

Step-by-step explanation:

(x +y)² = x² + 2xy +y²

-5(x + 3)² = -80

-5(x² + 2*x*3 + 3²) = -80          

-5(x² + 6x + 9) = -80

Divide the equation by (-5)

x² + 6x +9 = -80/-5

x² + 6x + 9 = 16

x² + 6x + 9 - 16 = 0

x² + 6x  - 7 = 0

x² - x + 7x - 7 = 0

x(x - 1)  + 7(x - 1) = 0

(x - 1)(x + 7) = 0

x -1 = 0   ; x + 7 = 0

x = 1     ; x = -7

Answer: Pythagorean Theorem in 3 D

sqrt ( 3^2 + 4^2 + 2^2) =

sqrt ( 9 + 16 + 4) =

sqrt( 29) = 5.3852 approximately

Step-by-step explanation:

The longest diagonal is about 8.9 inches. The longest length is going to be between the two longest lengths, the width and the height. The Pythagorean theorem is a^2 + b^2 = c^2. Plug the width and height into a and b of the Pythagorean equation. (4)^2 + (8)^2 = c^2. Now simplify the equation. 16 + 64 = c^2. 80 = c^2. Now find the square root of each side. (sqrt)80 = (sqrt)c^2. If you simplify this, you will find that c is equal to about 8.9 inches.

(9,1 ) is the solution of  64(x-8)²+ 12y² < 144 inequality.

A solution for an inequality in x and y are numbers such that when we substitute that number for x and y we have a true statement.

We substitute x = 9 and y = 1 in each inequality. The inequality, for which the values satisfy, has (9, 1) as the solution.

1.

x² - y² > 84

81 - 1 > 84

80 > 84

2.

x >= 3(y+2)² - 2

9 >= 3(3)² - 2

9 >= 27 - 2

9 >= 25
