Answer:
11). 3x² -x 12). -5x + 5
Step-by-step explanation:
11). (4x² + x) - (x² + 2x)
4x² + x - x² - 2x
4x² - x² + x - 2x
3x² -x
12). (6x - 3) - (11x -8)
= 6x - 3 - 11x + 8
= 6x - 11x - 3 + 8
= -5x + 5
You have to add all the numbers and then with that sum divide it by the number of numbers. In this case it would be 42+45+58+63+42+47+52=349. Now divide that by the numbers of numbers which in this case is 7, ~49.85(answer).
There’s no equation or picture?
We know that
<span>Total soil--------> 3/4 ton
</span><span>divide it by 8
(3/4)/8----> 3/(4*8)----> 3/32 ton----> 0.09375 ton----> multiply by 1000---> 93.75 kg
the answer is
</span>93.75 kg f<span>or each bed</span>
75/100 is less than 8/10.
8/10 can be equivalent to 80/100.
75/100 is less than 80/100.
Hope this helps.
