The given expression is:
4 - 8 (3/4) + 1/4
To start, we will convert all the numbers to be having a denominator of 4 as follows:
4 is equivalent to 16/4
-8 (3/4) is equivalent to -24/4
1/4 already has 4 as a denominator
Now, the new expression became:
16/4 - 24/4 + 1/4
Since they all have a common denominator, the result can be computed by adding numerators as follows:
16/4 - 24/4 + 1/4
= (16-24+1) / 4
= -7/4
The correct choice is:
A. -7/4
First blank: Rational
Second blank: 2/9
Third blank: 22/100 = 11/50
Fourth blank: irrantional
Fifth blank: no fraction equivalent
Sixth blank: perfect square
Seventh blank: non-perfect square
1186.30/999=1.187
1.187*1.187=1.409
Answer:
9 and 5.
Step-by-step explanation:
So we have the expression:
In order to combine like terms, the variables must be <em>exactly</em> the same: not one less, not one more.
3x²y and 2x² <em>cannot</em> be combined because the first value has a y.
7x², 3x²y, and 2x² also <em>cannot </em>be combined because the second value has a y.
9 and 5 is the only one that can be combined because they are just integers. They can be added to be 14.
2, 3, 5, and 9 <em>cannot</em> be combined because the 2 and the 3 are tied to the variables as coefficients. They are not constants.
