What all needs to be known in 8th grade math?
Firlakuza [10]

Answer:

Technically, it depends on which school you attend, which state, city, or area you live in, and if you have an honor-based program or just the basic class. Although, in the basic level of 8th grade, you will learn measurements, a bit of geometry, algebra, and probability.

Hope this helps and good luck!

Solve the simultaneous equation :<br><br> 4x+2y=17<br> 3x+2y=14
enot [183]

Answer:

(x, y) = (3, 5/2)

Step-by-step explanation:

4x+2y=17\\3x+2y=14

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

4x+2y=17\\-(3x+2y=14)

Now just add those from top to bottom.

\rightarrow (4x-3x)+(2y-2y)=17-14\\\rightarrow x=3

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

4x+2y=17\\\rightarrow 4(3)+2y=17\\\rightarrow 12+2y=17\\\rightarrow 2y=5\\\rightarrow y=\frac{5}{2}

(x, y) = (3, 5/2)
