(5+6)*6 Following the rules of PEMDAS you would have to put 5+6 in parentheses so multiplication wouldn't be first.

What is 4(x + 1) = 8.

Westkost [7]

$\bf{4(x+1)=8}$

Divide both sides by 4.

$\bf{x+1=\dfrac{8}{4} }$

Divide 8 by 4 to get 2.

$\bf{x+1=2}$

Subtract 1 from both sides.

$\bf{x=2-1 }$

Subtract 1 from 2 to get 1.

$\bf{x=1 \ \ \to \ \ \ Answer}$

<h2>Verification</h2>

Let x=1.

$\bf{4\times(1+1)=8 \ \ \to \ \ \ [Add] }$

$\bf{4\times2=8 \ \ \to \ \ \ [Multiply]}$

$\bf{8=8 \ \ \to \ \ \ [Equality \ holds] }$

Checked ✅

Write the number 3.8 in the form a/b using integers

Juliette [100K]

Answer:

3.8 = 38/10

Step-by-step explanation:

The given number = 3.8

We have to write 3.8 in fraction form a/b

Here we have 1 digit after the decimal. To get rid off the decimal number, we need to multiply both the numerator and the denominator by 10 since we have to 1 digit after the decimal.

$\frac{3.8 *10}{10}$

= 38/10

Therefore, the answer is 3.8 = 38/10

Thank you.
