I got you :)
-2x + 8 = 22
Subtract 8 from both sides....
-2x = 14 Divide by 2 on both sides....
<h2><u>x = -7</u></h2>
If we subtract the equations we can eliminate the 2 6y's
subtractiong the second from the first:-
10x = 44
x = 4.4
now plug x = 44 into the first equation:-
4*4.4 + 6y = 62
6y = 62 - 4*4.4 = 44.4
y = 44.4/6 = 7.4
the answer is the order pair (4.4,7.4)
Answer:
=6/7

Answer:
See below
Step-by-step explanation:
√120 is irrational since it cannot be written as a fraction
√36 is rational because it can be written as 6 or -6 which are both rational
7 is rational because it can be written as a fraction (ex. 7/1, 14/2, 21/3, etc.)
10 is rational because it can be written as a fraction (ex. 10/1, 20/2, 30/3, etc.)
148 is rational because it can be written as a fraction (ex. 148/1, 296/2, 444/3, etc.)
781 is rational because it can be written as a fraction (ex. 781/1, 1562/2, 2343/3, etc.)
