Answer:
$12.86
Step-by-step explanation:
multiply 13.50 by 0.05 and subtract the answer from 13.50
Answer:
20°
Step-by-step explanation:
The sum of angles in a ∆ = 180°
Therefore,
Use this expression to find the value of x, then find the measure of angle A.

Subtract 20 from both sides


Divide both sides by 20


Find measure of angle A.
Angle A is given as 
Plug in the value of x and solve

Answer:
Step-by-step explanation:
for reflection around x-axis.
(x,y)→(x,-y)
so P' is (-7,4)
Answer:
D
Step-by-step explanation:
A.
To solve, you need to get the variable by itself.
Order of operations:
Square root both sides.
(x-5)= plus/minus root 3, as 3 is not a perfect square.
Now you need to add 5 to both sides to get it to disappear on the side with the x.
x=root3 +or - 5, which can be rearranged so that 5 is the first term.
