Answer:

B) Collect variables terms on one side.

Step-by-step explanation:

Here, the given equation is,

$18=2(4+x)$

By Distributive property in right side,

$18=8+2x$

Subtracting 8 on both sides, ( Isolating variable x )

$18-8 = 8 + 2x-8$

Collect like terms,

$10=2x$

Dividing both sides by 2 ( Isolating variable x )

$5 = x$

Which is the solution of the given equation,

Hence, by the above explanation it is clear that we used all options except option B.

⇒ Option B would not be a step in solving 18=2(4+x).

B because there is only one variable in the equation.

Katarina [22]

Answer:

1.214 or $1\frac{3}{14}$ or $\frac{17}{14}$

Step-by-step explanation:

To solve this equation, first you need to the variable term isolated. You do this by adding 10 to each side. Your equation will now look like

17c = 14

Next, you will divide both sides by the 17.

Your equation now is solved, and above, I put ther three different forms for your answer: decimal, mixed number, and improper fraction.

What is the distance around a triangle with the sides measuring 2⅛, 3½ and 2½?

Marta_Voda [28]

So when you have data given this kind of form... you should convert to decimal first.
So that would be:
a ≈ 2.12
b = 3.5
c = 2.5
Now just place the simple perimeter formula, and sum all sides.

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w

TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer

Determine whether the improper integral converges or diverges, and find the value if it converges.

salantis [7]

Answer:

Integral will be diverging in nature

Step-by-step explanation:

We have given integral $\int_{5}^{\infty}\frac{3}{2}x^2dx$

Now after solving the integral

$[\frac{3}{2}\frac{x^3}{3}]$ limit from 5 to infinite

So $[\frac{3}{2}\frac{\infty^3}{3}]-[\frac{3}{2}\times \frac{5^3}{3}]=\infty$

As after solving integral we got infinite value so integral will be diverging in nature

A scientist is studying a form of bacteria that doubles every hour. if the petri dish starts with 2 grams of bacteria

strojnjashka [21]

Answer:

b = 2x²

Step-by-step explanation:

Let the number of bacteria = x

Every hour, the number of bacteria doubles itself, = x * x = x²

But the bacteria started with 2g,

The number of bacteria present is equal to

2 * x² = 2x².

At every hour, the growth of the bacteria is at 2x²
