Answer:

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

Tell whether the given number is a solution of each question. ( Must show work for credit)

guajiro [1.7K]

Answer/Step-by-step explanation:

1. $9 = 2a + 3$ ; 3

Let's solve for a.

$9 - 3 = 2a$ (subtraction property of equality)

$6 = 2a$

$\frac{6}{2} = a$ (division property of equality)

$3 = a$

$a = 3$

Therefore, 3 is a solution to 9 = 2a + 3

2. $5n - (-30) = 5$ ; 7

$5n + 30 = 5$ (- × - = +)

$5n = 5 - 30$ (Subtraction property of equality)

$5n = -25$

$\frac{5n}{5} = \frac{-25}{5}$ (division property of equality)

$n = -5$

Therefore, 7 is not a solution of $5n - (-30) = 5$

3. $4.4r - 2.8 = 1.6$ ; 1

$4.4r = 1.6 + 2.8$

$4.4r = 4.4$

$\frac{4.4r}{4.4} = \frac{4.4}{4.4}$

$r = 1$

Therefore, 1 is a solution of $4.4r - 2.8 = 1.6$ .

I want the answer to this problem<br> 3(x+2)-x=38

maks197457 [2]

Answer:

x = 16

Step-by-step explanation:

3(x+2)-x=38

Distribute

3x+6 -x = 38

Combine like terms

2x+6 = 38

Subtract 6 from each side

2x+6-6 = 38-6

2x = 32

Divide each side by 2

2x/2 = 32/2

x = 16

Solve for x. Evaluate and round your answer to 1 decimal place(tenths place). 10x=1200

Mandarinka [93]

Answer:

<h2>x = 3.1</h2>

Step-by-step explanation:

<h3> ${10}^{x} = 1200$ </h3>

<u>To solve first take logarithm to both sides</u>

That's

<h3> $log_{10}(10) ^{x} = log_{10}(1200)$ </h3><h3 /><h3> $log_{10}(10)^{x} = x log_{10}(10)$ </h3>

But

<h3> $log_{10}(10) = 1$ </h3>

So we have

$x = log_{10}(1200)$

<u>Write 1200 as a number with the factor 100</u>

That's

1200 = 100 × 12

So we have

<h3> $x = log_{10}(100 \times 12)$ </h3>

<u>Using the rules of logarithms</u>

That's

<h3> $log_{a}(x \times y) = log_{a}(x) + log_{a}(y)$ </h3>

Rewrite the expression

That's

<h3> $x = log_{10}(100) + log_{10}(12)$ </h3><h3 /><h3> $x = log_{10}(10)^{2} + log_{10}(12)$ </h3><h3> $x = 2 log_{10}(10) + log_{10}(12)$ </h3><h3> $log_{10}(10) = 1$ </h3><h3 /><h3> $x = 2 + log_{10}(12)$ </h3>

x = 3.079

So we have the final answer as

<h3>x = 3.1 to one decimal place</h3>

Hope this helps you
