Answer:
2494.756kg
*see below regarding significant digits
Step-by-step explanation:
Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.
*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.
The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.
2494.756kg

we know that, the mixture amount is the sum of 11 + p, or
11 + p = m.
we also know that, the total value is also a sum of
25.3 + 4.5p = 3.29m.

Answer:
143
Step-by-step explanation:
x2 + 12x + 6 + 3x + 1
substitute
(8)2+12(8)+6 +3(8) +1
distrubute
16+96+6+24+1
add like terms
143
Answer:
n=6
Step-by-step explanation:
Given -> -2(n+5)+6n=14
Distributive Property -> -2n-10+6n=14
Combine like terms -> 4n-10=14
Add 10 to both sides -> 4n=24
Divide both sides by 4 -> n=6
So n=6
