Answer:
9
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first
36/72 = 1/2
To find the next term, take the last term and multiply by the common ratio
18*1/2 = 9
Answer:
Michael (m) practiced 7 hours and Gen (g) practiced 5
Step-by-step explanation:
g+m+2=12
-2 -2
g+m=10
10 divided by 2 is 5
They both practiced free throws for 5 hours. Michael practiced two hours more that Gen. 5+2=7. Therefore, Michael (m) practiced 7 hours and Gen (g) practiced 5.
n, n+1 - two consecutive integers
n(n + 1) = 50 <em>use distributive property</em>
n² + n = 50 <em>subtract 50 from both sides</em>
n² + n - 50 = 0
-----------------------------------------------------
ax² + bx + c =0
if b² - 4ac > 0 then we have two solutions:
[-b - √(b² - 4ac)]/2a and [-b - √(b² + 4ac)]/2a
if b² - 4ac = 0 then we have one solution -b/2a
if b² - 4ac < 0 then no real solution
----------------------------------------------------------
n² + n - 50 = 0
a = 1, b = 1, c = -50
b² - 4ac = 1² - 4(1)(-50) = 1 + 200 = 201 > 0 → two solutions
√(b² - 4ac) = √(201) - it's the irrational number
Answer: There are no two consecutive integers whose product is 50.
Answer:
X=2
divide 3 on both side 3 cancles out on the left; 12 divided by 3 equals 4; divide 2 on both sides 2 cancels on the left; 4 divided by 2 is 2. so X=2
