do you mean total of all?
Since she has a base amount of $500, that will be your y-intercept. 20 is going to be your slope, and since she's withdrawing it, it will be -20. Here's how the equation would be set up (in y = mx + b):
-20x + 500 = 220
*Subtract 500 from both sides*
-20x = -280
*Divide both sides by -20*
x = 14.
Therefore, it will take 14 weeks.
Answer:
n = -8
Step-by-step explanation:
The variable has 4 subtracted and that quantity is multiplied by 5. You can find the value of the variable by reversing these operations, in reverse order. That means you first divide both sides of the equation by 5:
5(n-4)/5 = -60/5
n -4 = -12 . . . . . . simplify
Then you undo the subtraction of 4. You accomplish that by adding 4 to both sides of the equation.
n -4 +4 = -12 +4
n = -8 . . . . . . . . . simplify
_____
This equation can also be solved by first eliminating parentheses. Then you have
5n -20 = -60
Now, the variable is multiplied by 5, then 20 is subtracted from the sum. Reversing these operations in reverse order, we first add 20 to both sides of the equation:
5n -20 +20 = -60 +20
5n = -40 . . . . . . . . . . . . . simplify
Then we undo the multiplication by dividing both sides of the equation by 5:
n = -8
_____
The rule to remember is "whatever you do to one side of the equation must also be done to the other side". This is what keeps the equal sign valid.
Answer:
False
Step-by-step explanation:
The left side −28 does not equal to the right side 22 , which means that the given statement is false.
