Solve:<br><br> 7 = x + 12<br> A) -19 <br> B) -5 <br> C) 4 <br> D) 5
DaniilM [7]

<em><u>Hello, there! :)</u></em>

<u><em>Answer:</em></u>

<u><em>x=-5 </em></u>

<u><em>B. -5</em></u>

<u><em>*The answer must have a negative sign.*</em></u>

Step-by-step explanation:

Definition of subtraction property of equality.

Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

First, you had to switch sides.

x+12=7

Then, you subtract by 12 from both sides of an equation.

x+12-12=7-12

And finally, simplify or solve.

7-12=-5

x=-5

Hope this helps!

Thanks!

In a local shop some items are being sold at a third off. They now cost the following amounts. What was the original full price?
nasty-shy [4]

Answer:

1) 9.69

2) 87.36

3) 171.42

4) 18.75

5) 16.29

Step-by-step explanation:

Treat each value's full price as x. then, all of the values are (2/3)x. To get (2/3)x back to x, we must multiply (2/3)x*(3/2)=x. Multiply each of the questions given by 3/2 or 1.5

For the expression 6 + y - 3, determine the coefficient for the variable term.
aliina [53]
<h3>Answer:  C) 1</h3>

Explanation:

Think of 6 + y - 3 as 6 + 1y - 3

y and 1y are the same thing because 1 times any number is that same number.

The coefficient is the number to the left of the variable, so the coefficient is 1.
