Answer:
x > 6
Step-by-step explanation:
Given
3x + 10 > 28 ( subtract 10 from both sides )
3x > 18 ( divide both sides by 3 )
x > 6
S.I = PxRxT / 100
Therefore
S.I.= $10000x3x6/100
=$900
Answer:
<h2>

</h2>
Step-by-step explanation:


Solve the equation for y by moving 'x' to R.H.S and changing its sign


Substitute the given value of y into the equation 5x + y = 28

Solve the equation for x
Collect like terms

Move constant to R.H.S and change its sign

Subtract the numbers

Divide both sides of the equation by 4

Calculate

Reduce the numbers with 2

Now, substitute the given value of x into the equation y = 2 - x

Solve the equation for y

The possible solution of the system is the ordered pair ( x , y )
<h2>

</h2>
-------------------------------------------------------------
Let's check if the given ordered pair is the solution of the system of equation:
plug the value of x and y in both equation


Simplify the equalities


Since , all of the equalities are true, the ordered pair is the solution of the system.

Hope this helps....
