Answer: see attachment
<u>Step-by-step explanation:</u>
It would be -4.5 you can get that subtracting each element from the next one.-22.5-(-18)=-22.5+18=-4.5
Answer:
You would just divide $480 by 2 and get the answer of $240.
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:
161 boys
Step-by-step explanation:
First you find the even amount of boys and girls out of 386
386 divided by 2 = 193
Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys
(boys) 193 - 32 = 161
(girls) 193 + 32 = 225
So there are 161 boys and 225 girls
