Answer:
Step-by-step explanation:
Let number of songs are played in a commercial be a
number of songs are played in a movie be b
Adrian earned a total of $1010 -> a*40 + b*130 = 1010 (1)
14 commercials and movies -> a+b = 14 (2)
(1) - (2)*40 = a*40 + b*130 - a*40 -b*40 = 1010 -14*40
-> b*90 = 450
-> b = 5
-> a = 14-5 = 9
Which question do you need help with
Answer:
+ 8x³ + 12x² - 16x + 4
Step-by-step explanation:
Given
[(x² + 4x) - 2 ]² ← simplify contents of bracket
= (x² + 4x - 2)² = (x² + 4x - 2)(x² + 4x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x²(x² + 4x - 2) + 4x(x² + 4x - 2) - 2(x² + 4x - 2) ← distribute parenthesis
=
+ 4x³ - 2x² + 4x³ + 16x² - 8x - 2x² - 8x + 4 ← collect like terms
=
+ 8x³ + 12x² - 16x + 4
It cant really because 400,00 is greater than 400 so it would not work
Answer:
104
Step-by-step explanation:
women = 8/8
men = 5/8
all workers = 8/8 + 5/8 = 13/8
extra women workers = 8/8 - 5/8 = 3/8
so...
3/8 = 24
13/8 = x
( cross multiplication method)
3/8 x = 39
x = 104
Hence, there are 104 workers
