Answer:
x = -2
Step-by-step explanation:
Pull out like factors :
-3x - 6 = -3 • (x + 2)
Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x+2 = 0
Subtract 2 from both sides of the equation :
x = -2
The 1905 was 3.0 inches while 2004 was 4.2 inches since they are 1.2 apart and they add up to 7.2
Answer:
x+9=4x-4
=) x -4x = -4-9
=) -3x = -13
=) x = 13/3
It is not the form of ax 2 +bx +c =0
Answer:
55 decrease by 5 is 50, or 55 - 5 = 50.
Step-by-step explanation:
Let x represent the missing number.
When you hear the words decrease, minus, that tells you to subtract.
Before we subtract, if there is a variable, we must do the opposite of subtraction, we need to add.
50 + 5 = x
Which means x = 50 + 5.
50 + 5 = 55.
Therefore, x = 55.
