Answer:

±5

Step-by-step explanation:

Given equation ,

=> x² - 25 = 0

=> x² - 5² = 0

=> ( x +5)(x-5) = 0

=> x = ±5

Answer:

x = -5 or 5

Step-by-step explanation:

→ Factor the quadratic

( x + 5 ) ( x - 5 )

→ Equate each bracket to 0

x + 5 = 0 and x - 5 = 0

→ Solve each for x

x = -5 or 5

Answer:

the answer is x=-1

Step-by-step explanation:

The required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question below as:

5x + 1.2 = −3.8

We have to determine the solution to the given equation 5x + 1.2 = −3.8

⇒ 5x + 1.2 = −3.8

Rearrange the terms of non-variable in the above equation,

⇒ 5x =  - 3.8 - 1.2

Apply the addition operation,

⇒ 5x = -5

Divided by 5 both sides of the above equation,

⇒ x = -5 / 5

Apply the division operation,

⇒ x = - 1

Therefore, the required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

Answer:

You add all of the numbers of the set and how many numbers there are.

Here is an example:

The set is: {3, 7, 2, 9, 1}

There are five numbers, 3, 7, 2, 9, and 1. We then add all these numbers.

3 + 7 + 2 + 9 + 1 = 22

22 divided by 5 = 22/5 = 4.4

The average number between the set, "{3, 7, 2, 9, 1}" is 4.4.

Answer:

x=2 y=3

Step-by-step explanation:

first multiply equation 2 with (+2)

5x-2y=4

6x+2y=18

now add equation 1 to equation 2

11x=22

x=2 now substitute x=2 in equation 1 or 2

5(2)-2y=4 10-2y=4 -2y=4-10 -2y=-6 y=3

Answer:

[tex]x>\frac{27}{2}[/tex]

Step-by-step explanation:

[tex]-12x-38<-200[/tex]

add 38 to both sides of the inequality

[tex]-12x<-162[/tex]

divide by negative -12 on both sides of the inequality, flip the sign, and simplify

Answer:

$5.25

Step-by-step explanation:

The cost of 7 oranges is $5.25

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given;

Cost of 3 Oranges= 2.25

So, the cost of 1 orange= 2.25 / 3

                                       = 0.75

Now, the cost of 7 oranges

= 0.75 x 7

= $5.25

Hence, the cost of 7 oranges is $5.25

Answer:

True

Step-by-step explanation:

Multiplying a number by 3 will produce the same value as adding 6 to that number can be expressed algebraically as:

3x = x + 6

In order to determine whether the given statement is true, we can solve for x:

Start by subtracting x from both sides:

3x - x = x - x + 6

2x = 6

Divide both sides by 2:

2x/2 = 6/2

x = 3

Substitute the value of x into the original equality statement:

3x = x + 6

3(3) = 3 + 6

9 = 9 (True statement).

Therefore, it is true that when we multiply a number by 3, we get the same value as if we added 6 to that number.
