Answer:
x = - 1.10 and x = 1.10
Step-by-step explanation:
Given
25x² - 30 = 0 ( add 30 to both sides )
25x² = 30 ( divide both sides by 25 )
x² = [tex]\frac{30}{25}[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{30}{25} }[/tex]
x = - 1.10 and x = 1.10 ( to the nearest hundredth )
The correct answer is a. x = -1.10 and x = 1.10 .
To solve the quadratic equation [tex]\( 25x^2 - 30 = 0 \)[/tex], we first add 30 to both sides of the equation to isolate the quadratic term:
[tex]\[ 25x^2 = 30 \][/tex]
Next, we divide both sides by 25 to solve for [tex]\( x^2 \)[/tex]:
[tex]\[ x^2 = \frac{30}{25} \] \[ x^2 = 1.2 \][/tex]
Now, we take the square root of both sides to solve for x. Remember that when taking the square root of a number, we must consider both the positive and negative square roots:
[tex]\[ x = \pm\sqrt{1.2} \][/tex]
Using a calculator, we find the square root of 1.2 and round to the nearest hundredth:
[tex]\[ x = \pm1.095445115... \][/tex]
Rounded to the nearest hundredth, the solutions are:
[tex]\[ x = -1.10 \] \[ x = 1.10 \][/tex]
Therefore, the correct options are x = -1.10 and x = 1.10 . The other options provided [tex](\( x = -26.15 \)[/tex] and x = 1.15 , x = 0 , x = -0.83 and x = 0.83 are incorrect and do not satisfy the original equation.
The complete question is- Solve [tex]25x^2-30=0[/tex]
Round the answer to the nearest hundredth
a. x=-1.10 and x=1.10
b. x=-26.15 and x=1.15
c. x=0
d. x=-0.83 and x=0.83

The final amount of money was $50, they spent half of what they collected on canned foods, so 50 x 2 = 100.
They collected a total of $100.
Let the amount Eric collected = X
Charlotte collected 3 times as much minus $20, writing this as an equation you get 3x-20.
Now you have Eric plus Charlotte = $100:
x + 3x-20 = 100
Combine like terms:
4x-20 = 100
Add 20 to both sides:
4x = 120
Divide both sides by 4:
x = 120/4
x = 30
Eric = X = $30
Charlotte = 3x-20 = 3(30) - 20 = 90 -20 = $70
Answer:
40
Step-by-step explanation:
the the answer is 40 because if you do 40 * 3 to get 120 and if you minus 20 then you get a hundred in a hundred divided by 2 equals 50
what you do is you do 50 * 2 but you got to 100 then you add 20 which gives 220 then you ÷ by 3

What is the product? negative 9 x (5 minus 2x)
Answer:
18x²-45x
Step-by-step explanation:
Final answer:
To find the product of negative 9 and (5 minus 2x), use the distributive property, resulting in -45 + 18x.
Explanation:
The product of negative 9 and (5 minus 2x) can be found by applying the distributive property. This property states that a number multiplied by a sum or difference in parentheses is equivalent to the number multiplied by each term inside the parentheses separately, and then summing the results. So, the product will be:
Negative 9 multiplied by 5, which gives -45.
Negative 9 multiplied by -2x (note the two negatives make a positive), which gives 18x.
Combining these two products, we get the final answer, which is -45 + 18x.

i need help with a math problem right now it says A car rental agency advertised renting a car for $27.95 per day and $0.28 per mile. If David rents his car for 3 days, how many whole miles can he drive on a $200 budget
Answer:
David would have to drive for 415 miles before he reaches his $200 budget.
Step-by-step explanation:
It cost $27.95 per day to rent a car and he is only renting it for 3 days. ($27.95 x 3 = $83.85 for all three days). When you subtract $83.85 from his $200 budget you get, $116.15. It is .28 cents for each mile. Next you divide $116.15 by .28 cents to equal 414.82 miles. Round the miles to a whole number to get 415 miles.

In 2-15, estimate each product.
Answer:
the answer would be $3,582 dollars i hope u geta good grade and your welcome :3
Answer: The cost would be $1782 and $3582 respectively.
Step-by-step explanation:
Since we have given that
Number of MP3 players = 18
Number of CD/MP3 = 18
Cost of each MP3 = $99.00
Cost of each CD/MP3 = $199.00
So, the Cost of 18 MP3 would be
[tex]18\times 99\\\\=\$1782[/tex]
And, the cost of 18 CD/MP3 would be
[tex]199\times 18\\\\=\$3582[/tex]
Hence, the cost would be $1782 and $3582 respectively.

In the given figures figure C has no line of symmetry. Hence, option C is correct.
The line of symmetry is an imaginary line that divides an object into two equal and identical halves.
It is a reflectional symmetry, meaning that each point on one side of the line corresponds to an identical point on the other side.
This line can be vertical, horizontal, or even diagonal, depending on the shape or object being considered.
The line of symmetry is an important concept in geometry and can be found in various symmetrical objects like letters, shapes, and even faces.
If we rotate Figure C with respect to any axis we don't get an identical shape.
