3x - 50 = -20
Add 50 to both sides
3x = 30
x = 10
The number is 10
Answer:
C
Step-by-step explanation:
We can first move the variables to one side.
We can do this by subtracting 6x from both sides.
12x^2-6x=0
Now, we can factor out 6x.
6x(2x-1)=0
Since it equals 0, we know that 2x-1=0, or 6x=0.
This is because when ab=0, either a or b must equal 0.
So we can set both of these equal to 0 to solve.
6x=0
Divide both sides by 6.
x=0
2x-1=0
Add 1 to both sides.
2x=1
Divide both sides by 2.
x=1/2
Answer:
6
Step-by-step explanation:
because 6 times 6 =36 so the answer is 6
3% is the decimal 0.03 .
To make a number 3% bigger, multiply it by 1.03 .
The ' 1 ' part is the amount that's already there, and
the ' .03 ' part is the amount to be added onto it.
Answer:
3.44
Step-by-step explanation:
(-6.8 - c) / 1.2 = -2.8
(multiply both sides by 1.2)
-6.8 - c = -3.36
(add 6.8 to both sides)
-c = 3.44
c = 3.44
