Answer: -1
Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.
When we do that, we get
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.
So in our numerator we have 4 - 8.
Down below, we have -2 + 6 which is +4.
4 - 8 is -4 and -2 + 6 is +4.
Answer:
B. Days that are not Independence Day are not July 4. True
Step-by-step explanation:
"Independence Day in the United States is July 4" is a declarative sentence. It declares or asserts something.
The conditional form of the sentence would be, "IF it is Independence Day in the United States, THEN it is July 4".
The IF part is the hypothesis. The THEN part is the conclusion.
You form the inverse of a conditional statement by negating both its hypothesis and its conclusion:
If it is NOT Independence Day in the United States, then it is NOT July 4".
The closest sentence is, ”Days that are not Independence Day are not July 4." That statement is TRUE.
A and D are wrong. They each consist of two declarative sentences.
C is wrong. The statement is correct, but it interchanges the hypothesis and the conclusion of the original statement.
x^2-4x=60
<h2>In a meeting room for a business event, there are 4 fewer chairs laid out in each row than the number of rows. The total number of chairs in the room is 60.</h2><h2 />
If each row has the same number of chairs as rows, then there is x^2 chairs.
Because there is 4 fewer chairs in every row, for every row you minus 4 - 4x
There a 60 chairs in total.
x^2 - 4x = 60
Substitute a number into the formula to check:
If there are 10 rows:
x = 10
10^2 - 4(10) = 60
100 - 40 = 60.
