What is the solution of 3x+y=2 & 4y=12-12x?

Mathematics
1 answer:
lorasvet [3.4K]3 years ago
5 0

Answer:

Step-by-step explanation:

3x+y=2............(1)

4y=12-12x........(2)

Making y as subject in (1) and substitute in (2)

y = 2 - 3x......(3)

4(2 - 3x) = 12-12x

8 - 12x = 12 - 12x

12x - 12x = 12- 8

0 = 4

So no solution since variable cancelled out

8.25 × 10–4 in standard form.
Elanso [62]

The 10^-4 means that the decimal point is 4 places to the left of where it is in 8.25 (if the exponent was positive the decimal point would be to the right). If you move the decimal point 4 places to the left you get an answer of 0.000825 which is 8.25 * 10^-4 in standard form.

How many 1/10s in 2 3/5
Umnica [9.8K]

It'd be clearer if you'd write:  "How many tenths are there in 2 3/5?"

2 3/5        13/5

---------- = ---------- = 26

(1`/10)        1/10

There are 26 tenths in 2 3/5.
