Twenty four plus (negative nine) minus forty-four plus thirty three minus seventeen.
<u>Answer:</u>
D. |–c| = 3 and –|d| = 4
<u>Step-by-step explanation:</u>
We are given these values of two variables and asked which of the statements in the given options is true:
c = –3 and d = 4
In mathematics, we know that the absolute value or modulus of a real number x is the non-negative value of x despite of whatever sign it has, positive or negative.
Therefore, the modulus of c |–c| = 3 and modulus of –|d| = 4 so option D is the correct one.
Answer:
A) x = 12
Step-by-step explanation:
4x-6 = 42
4 = 48
x = 12
7x+10 = 94
7x = 82
x = 12
Answer: Average or Mean
Step-by-step explanation:
The center of measure calculated was the average or mean. To get the mean of a set of numbers, we have to add all the numbers given and then divide them by the numbers.
In this case, the mean of 3,7,11,11,16 will be:
= (3 + 7 + 11 + 11 + 16) / 5
= 48/5
= 9.6
Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
