X = 7
Rearrange -> 2•X+5- (19) = 0
Pull out the like terms -> 2x -14 = 2 • (X - 7)
Solve -> 2 = 0
X- 7 = 0
So, that means "X" -> 7
Answer:
20
Step-by-step explanation:
90-50=40... therefor X must equal 20
Answer:
y = 3x + 11
Step-by-step explanation:
obviously since y is 11 when x is zero the constant term is 11.
Then use the other coordinates to find the cooefficent of x.
-4= c × -5 + 11
-4= -5c + 11
5c=15, c=3
Therefore the equation should be:
y= 3x + 11
Answer:5m+22-15n
Step-by-step explanation:
Given:
Number = -9.1
To find:
The magnitude (size) of given number.
Solution:
We know that, magnitude of a number is the absolute value of that number.
So, magnitude of -9.1 is
Because, absolute value of a number is always positive.
Magnitude of -9.1 is 9.1 because .
Therefore, the correct option is A.
