For this case, we must clear the value of the variable "x" of the following equation:
First, we must bear in mind that can be simplified as:
So, we rewrite the equation:
We multiply by "6" on both sides of the equation:
So, the value of x is 5
Answer:
Option c
Answer:
Step-by-step explanation:
The given expression is
If we evaluate the expression as it is we will get;
But we want to insert parenthesis so that we will use PEDMAS to obtain 37 as the result.
The only way this can be achieved is when we insert the parenthesis as shown below;
Answer:
B
Step-by-step explanation:
9514 1404 393
Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)
Answer:
40
Step-by-step explanation:
The equation above is related to the model.
The 25 covers 5 out of 8 blocks. so 1 block has a value of 5 and there are 8 blocks therefore just like the equation the answer is 40
Hope this answer helped you
