-2 < x-1 < 2 ... see note1 below

-2+1 < x-1+1 < 2+1 ... see note2

-1 < x < 3

Note1: use the rule that |x| < k turns into -k < x < k for some positive real number k.

Consider the system of linear equations. x + y = 9.0 0.50 x + 0.20 y = 4.05 Find the values of x and y .

mixas84 [53]

Answer:

x=7.5

y=1.5

Step-by-step explanation:

$x + y = 9.0$

subtract x from both sides

$y=9-x$

$0.50x + 0.20y= 4.05$

$0.50 x +0.20(9-x)= 4.05$

$0.50x+1.8-0.2x= 4.05$

combine like terms

$0.30x+1.8= 4.05$

subtract 1.8 from both sides

$0.30x=2.25$

divide both sides by 0.3

x=7.5

$y=9-x$

$y=9-7.5$

y=1.5

5n – 2n<br> I need help asap

blondinia [14]

Combining those like terms would end as 3n.

Explanation: The end of a subtraction equation is basically just the negative number, except you add it to the other part.

For example, 2n is really -2n, and you just add -2n to 5n (which is positive,) and you get 3n.
