Answer:
x=20,y=34
Step-by-step explanation:
x+14=2x-6 (vertically opposite angles)
x-2x = -6-14
-x = -20
x=20
x+14=y (corresponding angles)
20+14=y
y=34
The solution of the expression is n = 3 and all the correct statement are shown below.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is;
⇒ - 7n + 11 = - 10
Now,
Solve the expression as;
Steps Reasons
⇒ - 7n + 11 = - 10 Given
⇒ - 7n + 11 - 11 = - 10 - 11 The property of equality was applied
⇒ - 7n = - 21 Addition and subtraction of numbers
⇒ - 7n / -7 = - 21/-7 The property of equality was applied
⇒ n = 3
Thus, The solution of the expression is n = 3 and all the correct statement are shown above.

Step-by-step explanation:
Answer:
light takes 3×10^5 second s
so total seconds taken by the light =780×10^6/3×10^5
1 min=60sec
no. of min=2600/60
=43333min
