Answer:X to the power of 3.
Step-by-step explanation:
Using one of laws of indices..The two entities have the same bases which is X, so all we have to do is to add their powers. Adding 7/3 and 2/3 gives 3.
Answer:
<h2>x = 5/7</h2>
Step-by-step explanation:
-4x + 1 = 3x - 4 <em>subtract 1 from both sides</em>
-4x = 3x - 5<em> subtract 3x from both sides</em>
-7x = -5<em> </em>divide both sides by (-7)
<em>x = 5/7</em>
Adding both equations will eliminate a variable in the system of equations
Step-by-step explanation:
Given equations are:
One of the methods to solve simultaneous linear equations is elimination. In elimination one of the variables is eliminated from the system to find the value of other variable.
In the given equations we can see that the coefficients of y in both equations are same with opposite signs so adding both equations will eliminate the variable y from the system.
Hence,
Adding both equations will eliminate a variable in the system of equations

The plant grow 3.6 centimeter in 18 days and the student written it incorrectly as 1.44 days.
Division:
Division is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. It is a reverse process of multiplication.
Given:
The ratio of growth for a plant is 0.2 centimeters per 0.5 day.
A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days.
Here we have to verify if the student is found the correct value or not.
For one day the plant grow 0.2 centimeter.
So, for 3.6 centimeter it will take
=> 3.6 / 0.2
=> 18
So, for 3.6 centimeter it will take 18 days.
So, here the student written it incorrectly as 1.44 days.
