(−12a^3b)(7ac+2b^2)
Step-by-step explanation:
(−24a^3(b^3)−84a^4bc
−84a^4bc−24a^3b^3=
(−12a^3b)(7ac+2b^2)
First of all we are going to take $7.25 and multiply it by 3 here is the math
7.25 x 3 = 21.75
so this means he makes 21.75 dollars a day.
since there are 365 days a year. Now i'm not saying he worked every single day but the question does not say other wise
so we would take 21.75 and multiply it by 365 heres the math
21.75 x 365 = 7,938.75
this means he makes 7,938.75 dollars a year!!
your welcome

30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
Answer:
A) infinitely many solutions
Step-by-step explanation:
2x - y = 8
4x - 2y = 16
simplify the first equation
2x - y = 8
2x = 8 + y
2x - 8 = y
y = 2x - 8
substitute y for 2x - 8 in the second equation
4x - 2y = 16
4x - 2(2x - 8) = 16
4x - 4x + 16 = 16
4x - 4x = 16 - 16
0x = 0
since no matter what x is, 0 = 0, the answer is infinitely many solutions
