Answer:
the answer would be 21x^3 - 12x^2y^4, because you want to multiply 3x^2 and 7x first to make 21x^3, and then multiply 3x^2 and -4y^4 to get -12x^2y^4. hope that helps!
This would be 16
I hope this helped!!!
2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
5 or 1/2 since it's numerator and denominator are integers
Answer:
6.8h
Step-by-step explanation:
5 tasks in 34h
So 1 task is taking 34/5 h
34/5 = 6.8h
1 task is taking 6.8h to complete
