Answer:
cost of 5 story book=800
cost of 1 story book=800/5
=160
how many. book can be bought on rs.1400
=1400/160
=8.75
Step-by-step explanation:
=
<h2>
x = 9</h2><h3 />
<u>We know:</u>
- we can add/subtract the same expression to both sides of the equation to get an equivalent equation;
- we can multiply/divide both sides of the equation by the same non-zero number to get the equivalent equation.
<u>Equivalent equations</u> are algebraic equations that have identical solutions.
We have the equation:
<h3>SOLUTION:</h3>
<em>multiply bot sides by 3</em>
<em />
<em>divide both sides by 7</em>

Answer:
See below in bold.
Step-by-step explanation:
To do these we add or subtract 360 degrees or 2 pi radians. Sometimes multiple actions are required.
11. Adding 360 to -545:
= -185
185 + 360 = 175
The other angle is 185 degrees so they are not coterminal.
12. 161pi/36 - 2pi
= 161pi /36 - 72pi/36
= 89pi/36
89pi/36 - 72pi/36
= 17pi/36.
So these are coterminal.
13. -330 + 360 = 30 degrees.
14. -435 + 360
= -75
-75 + 360
= 285 degrees
15. 640 - 360 = 280 degrees.
16. -442 + 360 = -82
-82 + 360 = 278 degrees.
Answer:
According to my algebra calculator: -4.35808478
Step-by-step explanation:
I would say -4.
Not 100% sure.
I hope this is right!
Answer:
A
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
Here the line passes through all points with an x- coordinate of 4, thus
x = 4 → A
