Answer:
Erin gets a result number of 5
Step-by-step explanation:
Assuming this is a 'word problem.' -- These are small numbers so you could use your hand for visual. :)
Start with 4 fingers up. (adding a negative to a positive is basically subtraction sooo...) put 3 fingers down. You now have one finger up. (subtracting a negative is just addition, think about taking those two minus signs and putting them together to get an addition sign.) now add 4 fingers to your one finger. You should be left with 5 fingers up!
Hope I helped. Hang in there, it will get easier!
Answer:
Step-by-step explanation:
All the variables on the right are being multiplied together then the whole mess is being divided by 2. Let's get rid of the 2 first. The undoing of division is multiplication, so we will begin by multiplying both sides by 2 to get
Next we will move the m. The undoing of multiplication is division. So we divide both sides by m to get
The undoing of a square is to take the square root, so we will do that to both sides giving us, finally
The probability is 7/20.
There are 20 outcomes in the sample space:
2(1) 2(3) 2(5) 2(7) 2(9)
3(1) 3(3) 3(5) 3(7) 3(9)
4(1) 4(3) 4(5) 4(7) 4(9)
5(1) 5(3) 5(5) 5(7) 5(9)
Out of these, 14 are two digit products. Out of those 14, only 7 are odd. Thus the probability is 7/20.
Answer: The quantity demanded is decreased by 20%.
Step-by-step explanation:
Since we have given that
Price elasticity of demand = 2
Percentage change in price = (+)10%
We need to find the percentage change in quantity demanded.
As we know the formula:
As we know that there is inverse relationship between the price and quantity demanded.
Hence, the quantity demanded is decreased by 20%.
Answer:
w-9x/5=y
Step-by-step explanation:
It really isn't that hard. Don't let the other variables confuse you. First get everything else on one side. So, subtract 9x from w. You can't really do that, so you just leave it as w-9x.
Then you are left with w-9x=5y. This is like a 2-step equation. So divide 5 on both sides. Doing this leaves you with w-9x/5=y.
Thank you.
