Are the roots equal or unequal

Answer:

-20 = - 20

Step-by-step explanation:

Suppose the number is x

three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.

So we can write

x - 3 = 2x +14 - - - - - A

subtract x from both sides

x - x - 3 = 2x - x +14

-3 = x +14

Subtract 14 from both sides

-3 - 14 = x +14 - 14

-17 = x

Or x = - 17

Now can verify our answer by putting the value of x in Eq A

-17 - 3 = 2 x (-17) +14

-20 = - 34 +14

-20 = - 20

can I please get the brainliest I only have 1 pls

Answer:

76.38 g

Step-by-step explanation:

Below expresion can be used in calculating the remaining amount of radium

A(t)=A(0) (1/2)^(t/h)

Let A(t)=the remaining amount of radium

Let A(0)= amount of radium at the beginning= 90 grams

t= amount of time in years= 400 years

h=the half-life time= 1690 years

A(t)=A(0) (1/2)^(t/h)

If we substitute the values into the expresion we have

A(t) = 90 × (1/2)^(400/1690)

A(t)= 76.38 g

Answer:

Let's solve for x.

3x+y=−6

Step 1: Add -y to both sides.

3x + y + −y = −6 + −y

3x = − y − 6

Step 2: Divide both sides by 3.

3x  / 3  =  − y −6 /  3

x =  − 1  / 3 y −2

Answer:

x = − 1  / 3 y −2

Answer:

3 x 2 or 3 + 3

Given: Taylor noticed the rectangle she could multiply 2 times 3 to get its area of 6 square inches.

so, if we did 3 times 2 its 6 but if we did 3 + 3 it also 6 so therefore she could do 3 x 2 or 3 + 3 to find the area.

C. 3.078

Step-by-step explanation:

14.1005 - 11.023 = 3.0775

Then you round the ten thousands place turning 75 into 8 equaling 3.078

Subtraction is a mathematical operation. The amount of silver lab group A got compared to lab group B is 3.0775 gm more.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The amount of silver that group A got is 14.1005gm, while the amount of silver that group B got is 11.023 grams. Therefore, the amount of silver lab group A got compared to lab group B is,

14.1005 gm - 11.023 gm = 3.0775 gm

Hence, the amount of silver lab group A got compared to lab group B is 3.0775 gm more.

Answer:

the area of the circle is 19.615

Answer:

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

[tex]z - 2 = \frac{125}{25} [/tex]

2) Simplify 125/25 to 5.

[tex]z - 2 = 5[/tex]

3) Add 2 to both sides.

[tex]z = 5 + 2[/tex]

4) Simplify 5 + 2 to 7.

[tex]z = 7[/tex]

Thus, the answer is z = 7.

Answer:

the answer to your question is 21

Answer:

Step-by-step explanation:

In this question we have to find the share of each person

First we have to find the sum of all the ratios,

[tex]2 + 3 + 5 \\ = 10[/tex]

Then we have to represent their share as a fraction and then multiply it by the total value,

The share of first person:-

[tex] \frac{2}{10} \times 450000 \\ = 2 \times 45000 \\ = 90000[/tex]

So the first person share is $90,000

The share of second person:-

[tex] \frac{3}{10} \times 450000 \\ = 3 \times 45000 \\ = 135000[/tex]

So the second person share is $135,000

The share of third person:-

[tex] = 450000 - (135000 + 90000) \\ = 450000 - 225000 \\ = 225000[/tex]

So the third person share is $225,000
