6x-4y=-15 and x-4y=1
Harlamova29_29 [7]

Answer:

The solution to the given system of equations is

(-\frac{16}{5},-\frac{21}{20})

Step-by-step explanation:

Given system of equation are

6x-4y=-15\hfill (1)

x-4y=1\hfill (2)

To solve equation by using elimination method

Now subtracting equations (1) and (2)

6x-4y=-15

x-4y=1

_________________

5x=-16

x=-\frac{16}{5}

Substitute x=-\frac{16}{5}  in equation (1)

6(-\frac{16}{5})-4y=-15

-\frac{96}{5}-4y=-15

-4y=-15+\frac{96}{5}

-4y=\frac{21}{5}

y=-\frac{21}{20}

Therefore the solution is

(-\frac{16}{5},-\frac{21}{20})

Round 483 to the nearest ten
madam [21]
To round to the nearest ten, we will look at the number in the ones place, and determine if it is higher, lower, or equal to 5. In this case, 3 is less than 5, so we round down. This means that 483 rounded to the nearest ten is 480. :) I hope this helps you in the future! A common phrase you can think about is:
Four or less, give it a rest. 5 and above, give it a shove.
