Answer:

C. 7x + 45

Step-by-step explanation:

To start answering this question, let's first distribute the 6 * ( x + 7 ) so that we can add like terms to simplify.

So let's multiply the 6 out to the ( x + 7 ) to get ( 6x + 42 ).

Now the complete expression reads: 6x + 42 + ( x + 3 )

With this, we can add all the like terms( 6x and x, and 42 and 3) together.

So we end up with 6x + x + 42 + 3 = 7x + 45

So the correct answer is C. 7x + 45

Andrew is showing his work in simplifying −4.5 + 4.2 + 5.6 − 7.3. Identify any errors in his work or in his reasoning. Write fee
Vinil7 [7]

Solving the expression -4.5 + 4.2 + 5.6 -7.3 we get -2.

Comparing the solution with the one given, you can find the errors.

Step-by-step explanation:

We need to simplify -4.5 + 4.2 + 5.6 -7.3 and identify errors.

Since the steps are not shown, so we cannot identify errors but I can solve the expression and you can compare to find errors.

Simplifying:

-4.5 + 4.2 + 5.6 -7.3

Using algebraic rule: if one digit has positive (+) sign and other digit has negative (-) sign then we will perform subtraction. and after subtraction, the sign of bigger value will be the sign of result.

Using the rule and solving:

=(-4.5 + 4.2) + 5.6 -7.3

=-0.3 + 5.6 -7.3

=(-0.3 + 5.6) -7.3

=5.3 -7.3

=-2

Solving the expression -4.5 + 4.2 + 5.6 -7.3 we get -2

Comparing the solution with the one given, you can find the errors.

What is 0.32 repeating as a fraction in the simplest form
maxonik [38]

Answer:

32/99

Step-by-step explanation:

Here's a formula you could use,    

(DN x F) - NRP over D

DN = Decimal Number

F = 10 if one repeating number, 100 if two repeating numbers, 1000 if three repeating numbers, etc.

NRP = Non-repeating part of decimal number.

D = 9 if one repeating number, 99 if two repeating numbers, 999 if three repeating numbers, etc.

0.32 repeating as a fraction

(0.32 x 100) - 0/99 = 32/99

Simplest form:

32/99
