Answer:
Step-by-step explanation:
-2 * -30 = 60 ( since the multiplication of negatives gives positive )
Answer: The answer is B. Have a nice day.
Step-by-step explanation: Plz make brainliest. (I only need 1 more to become an expert!)
The answer would be 2000, because you would round the 19 to 20 and then just at the 2 zeros representing the thousands. So you would be left with 2000 as your final answer.
You would graph this the same way you would any other y = mx + b equation, only, in this case, there isn't a y-intercept present in the equation. it's just y = mx.
y = 1/2x -- what you do is plug in x-values, then get the y-value and graph the point. choose easy numbers so the math won't cause you too much trouble (numbers like 1, 2, -1, and -2 are usually easy enough).
when x = 1...
y = (1/2)(1)
y = 1/2
(1, 1/2)
when x = -1...
y = (1/2)(-1)
y = -1/2
(-1, -1/2)
when x = 2...
y = (1/2)(2)
y = 1
(2, 1)
when x = -2...
y = (1/2)(-2)
y = -1
(2, -1)
that should be enough to sketch a graph. if you need more points, just follow the same process and plug more x-values in to get your y-values.
Answer:
$75
Step-by-step explanation:
Answer:
$28.83
Step-by-step explanation:
We will use: and then use cross multiplication.
Let's solve the first sale
We have:
percent = 25%
whole = $200
we want to solve for "part". Lets set the equation up before we plug anything in
now plug everything in:
part = $50
what does this mean?
Well it actually means $50 is the amount of money we take away from our original price of $200.
So we subtract that from our total.
$200 - $50 = $150
Next we will do the second sale.
percent = 50%
whole = $150
Use the same equation as above:
part = $75
