Petra is 13 and her mother is 32. I used this equation:
if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.
Answer:
Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank.
12/4=3
So if I added another 1/4 to the capacity:
It could hold 15 gallons.
All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.
15x2=30
30 bottles.

Answer:</h2>
<u>The pressure will be 176 k Pa</u>
<h2>
Step-by-step explanation:</h2>
Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as
P1V1 = P2V2
By arranging the equation we get
P1V1 / V2 = P2
Putting the values
(132 x 20 ) / 15 = P2
P2 = 176 k Pa

Answer:
7x^2 + 14x - 12
Step-by-step explanation:
Add like terms:
(4x + 8x - 5) + (3x2 + 6x - 7) becomes:
4x^2 + 8x - 5 or (grouping like terms in columns):
+ 3x^2 + 6x - 7
---------------------
7x^2 + 14x - 12
