70-40= 30
30/2 = 15
40/2= 20
15 x 20 = 300
Answer:
B) 1
Step-by-step explanation:
Answer: 6 days
Explanation
You can set it up as a algebraic equation like this
X= the number of days
2/3x= 4
•(3/2) •(3/2)
X=6
We have that
v=9√p-----> squaring both sides-----> v²=9²(√p)²
p=v²/81
v=72 ft/sec
substitute the value of v in the formula
p=(72)²/81------> p=64 psi
the answer is 64 psi
The distributive property is the only property that uses addition and multiplication at the same time in a problem.
