Answer:
3×10+2×-2
30+(-4)
30-4
26
Step-by-step explanation:
3x10+2x(-2)
you first solve the bracket
2x(-2)=-4
solve the multiplication
3x10=30
then, 30+(-4)=26
sure what's up
Let cases of Lyme disease = x
x = 2, 1, 3, 4, 5, 1, 2, 1, 6, 5, 4, 1
y = 0, 1, 2, 1, 3, 5, 2, 3, 3, 3, 1, 0
b) Linear correlation between Lyme disease and drowning deaths.
r = -15/ √(24*36.92)
r = -0.504
x = 11
Combine the like terms in the given 7x-12=6x-1:
7x - 6x = -1 + 12, or
y = -3x + 5
You want it in y = mx + b form
-5 = -y - 3x
Add y to both sides
-5 + y = -y + y - 3x
-5 + y = -3x
Add 5 to both sides
- 5 + 5 + y = -3x + 5
The new pressure will be 8 kPa.
Explanation
Lets assume, the pressure of the gas is P and volume is V.
P is inversely proportional to V means : , where is a proportional constant.
First, it is given that, Volume of hydrogen is 3.67 liter with a Pressure of 4 kPa
Now plugging V= 3.67 and P= 4 in the above equation:
Now, we are moving all of the hydrogen to a 1.835 liter container. That means now the Volume is 1.835 liter
Plugging V= 1.835 and k= 14.68 into the original equation ,
So, the new pressure will be 8 kPa.
