Answer:
-240
Step-by-step explanation:
Since 20 is right next to -12 that means you have to multiply.
Answer:
y=-2x-4
Step-by-step explanation:
6x + 3y=-12 subtract 6x to other side
3y=-12-6x divide 3 to every number
1y=-4-2x
Answer:
$ 850
Step-by-step explanation:
Martha and her brother started their own car-washing business.
We need to use front-end estimation to find out about how much their business will earn in 5 weeks.
Amount charged per car = $8.50
Number of cars washed per weekend = 22
Therefore, amount earned per weekend = Amount charged per car × Number of cars washed per weekend = 8.50 × 22 = $ 187
Amount earned in 5 weeks = amount earned per weekend × 5 = 187 × 5 = $ 935
Therefore, their business will earn $ 935 in 5 weeks.
Answer:
x= -1
Step-by-step explanation:
1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.
2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.
3. That will leave you with 14x= -14.
4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.
5. That will leave you with x= -1. That is your final answer.

Answer:
The answer is "option C".
Step-by-step explanation:
Distinctions are also the mean squared variance just are calculated as the number of standard differences divided by "N" and for a population. After all, if a sample uses this very same definition.
- Its standard deviation would become partially skewed as well as the resulting community value becomes continuously underestimate.
- Its experimented formula consequently includes a correction modification for a bias. Its modification involves dividing by instead of n.
