<span>3(9x-9)=16+3(-2x+9)
27x - 27 = 16 - 6x + 27
27x + 6x = 16 + 27 + 27
33x = 70
x = 70/33
x = 2 4/33
In short, Your Answer would be 70/33 or 2 4/33
Hope this helps!</span>
Answer:
x = 18.64
Step-by-step explanation:
use tan:
⇒ tan = 
⇒ tan 46 = 
tan of 46 is 1.0355
⇒ 1.0356 = 
multiply 18 on both sides
⇒ 1.0355 x 18 =
x 18
⇒ 18.64 = x

Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.
Explanation:
The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.
If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.
The given expression is,

Use multiplication property of equality, multiply 5 both sides,


Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
Answer:
A.
B. 25% discount
Step-by-step explanation:
PART A:
For the shirt:
