Answer:
x= 10, x=1
Step-by-step explanation:
(x-1)(x-10)=0
then solve for x
I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:
Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:
64 ÷ 4 = 16
So, we have used mental arithmetic to solve a more complex problem.
Answer:
T= 25
Step-by-step explanation:
140-15=125
After that divide 125 by 5.
You get 25.
REMEMBER TO DOUBLE-CHECK JUST IN CASE!
For this case we have a factored expression, of a second degree equation:
(
To find the solutions:
we add 3 to both sides of the equation:
We subtract 8 on both sides of the equation:
Thus, the solutions of the equation are:
