Hi there!
Answer:
<u><em>A. 12. x=12 and 12=x</em></u>
Step-by-step explanation:
addition property of equality is adding the same number both sides of an equation does not change the equation.
subtraction property of equality is subtraction the same number from both sides of an equation does not change the equation.
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
division property of equality is dividing both sides of an equation by the same number non-zero number does not change the equation.
x-6=14-8
subtract by 6 both sides of an equation.
x-6=6
add by 6 both sides of an equation.
x-6+6=6+6
simplify.
6+6=12
x=12
12-6=6
Hope this helps!

Have a great day!
Answer: 54 lattes were sold
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
If each latte costs $4 , each cappuccino cost $3, and sales totaled $252:
4 x + 3y = 252
Where
x = number of lattes
y = number of cappuccinos
The number of lattes sold was 6 more than 4 times the number of cappuccinos. Mathematically speaking:
x = 4y +6
Now, we have the system:
a)4 x + 3y = 252
b)x = 4y +6
Replacing the value of x in a) for b):
4 (4y +6) +3y =252
16y +24 +3y =252
16y +3y =252 -24
19y = 228
y= 228/19
y = 12
Replacing the value of "y” in b ) for the value obtained:
b)x = 4y +6
x = 4 (12) +6
x = 48+6 = 54
x =54
So , 54 lattes were sold.
If the slope if is undefined, then the line is vertical.
The equation of a vertical line: x = a (a - any real number).
The line passes through the point (-3, 0) → x = -3 and y = 0.
Therefore we have x = -3.
The general form of a line: Ax + By + C = 0.
x = -3 <em>add 3 to both sides</em>
<h3>x + 3 = 0</h3>
With what? There’s no picture
The answer for this question is very tricky but is to work out its B.
