Answer:
42 3/4 I think
Step-by-step explanation:
because if you simplified 342/8 it will be 171/4. so if you simplified that it'll get you to 42 3/4
7^3
That's how you right that in exponent form, I don't really know how to explain it.
Solve by substitution
Just plug in y=-x-1 into y+x=3
So we get:
Simplify that:
And since that is not true, that means this system of equations has no solutions!
Estimation is a process by which we do not exactly do the operation but predicts through pre-known facts and methods in order to determine the required. In this item, we are to predict or estimate the place of the decimal point to the answer when we divide the 42.56, dividend, and 22, our divisor.
We can say that 42 can be divided by 22 only once because twice of 22 is already 44. By this we can say that the decimal place will be after 1. There would only be one digit to the left side of the decimal point.
If we are going to answer the division problem, we get an answer of 1.934545..
Answer:
When a power is taken on both sides of an equation, the resulting solutions might not check in the original radical equation. These are called extraneous solutions. You must check solutions by substituting in the values into the original equation and verifying that it produces a true statement.
