Answer:
the answer is a
Step-by-step explanation:
Let the number of bags that he would have been used to put 3 kg of apples be x. Thus the number of bags that would be used to put 2kgs will therefore be (x+9), hence the total number of kgs the bags will hold will be given by:
3*x=3x kgs
2(x+9)=(2x+18) kgs
since the total weights are the same then:
2x+18=3x
hence
18=3x-2x
18=x
thus the number of bags required to put 3 kgs of apples will be 18. Thus the total Kgs of apples was:
3x
=3*18
=54 kgs
330 minutes watched
330 ÷ 4 = 82.5 mins
1 hour 22minuites and 30 seconds spent watching
A = 6(1/3)²
A = 6(1/9)
A = 6/9 or 2/3
Hope this helps :)
Answer:
The equivalent expression is 3x^5-9x^3-2
Step-by-step explanation:
To find the equivalent expression, we need to
open up the brackets;
Thus;
x^2(3x^3 -2x) - (7x^3 + 2)
= 3x^5 -2x^3 -7x^3 -2
= 3x^5 -9x^3-2
