What is -0.8+1.4n=2+0.7n

Sergio [31]

Answer:

n=4

Step-by-step explanation:

To solve combine your like terms.

You can start by adding 0.8 to both sides and subtracting 0.7n from both sides.

$-0.8+1.4n=2+0.7n\\1.4n=2.8+0.7n\\0.7n=2.8$

Next, divide both sides by 0.7 to isolate for n.

$0.7n=2.8\\n=4$

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs t

Fittoniya [83]

Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) = $3x^5-4x^4+25x^3-80x^2+130x-200$

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.
