Answer:
m = 299
Step-by-step explanation:
When isolating variables, you must do the same thing to both sides of the equation. To isolate "m", you must add 77 to both sides.
m - 77 = 222 <----- Original equation
+77 +77 <----- Add 77 to both sides
m + 0 = 299 <----- Resulting equation
m = 299 <----- Rewrite
Answer:
-8 or +7
Step-by-step explanation:
Let x represent the number. The the problem statement tells us ...
x² + x = 56
x² +x -56 = 0 . . . . . subtract 56 to put into standard form
(x +8)(x -7) = 0 . . . . factor
Solutions to the equation are values of x that make the factors zero:
x = -8 . . . or . . . x = +7
The number could be -8 or +7.
_____
<em>Check</em>
For x = -8, the square is (-8)² = 64. Adding -8 to that gives 64-8 = 56.
For x = 7, the square is 7² = 49. Adding 7 to that gives 49+7 = 56.
Answer:
B, irrational
Step-by-step explanation:
We know that π is irrational, since it can not be written as a division between natural numbers (a sub class of Real numbers called N), it's value is 3,1415(a whole bunch of decimals after this)
If you remove the decimal part of π by subtracting the integer part of it, that is the number 3. the result will still being and irrational number
Since π= 3(the rational part) +0,1415... (the irrational part)
The resut of π-=3= 0,1415...
Answer:
the another answer is a virus guys
Multiply 1st equation by 2
2y + 14 = 6x
6x - 2y = 14 (rewrite)
6x - 2y = 12 (2nd equation)
