For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
Answer:
-2> 7+35
-2>42
0<21
the answer is 0 is less than 21
Answer:
x>-1
Step-by-step explanation:
Hope this helps. Plz give brainliest.
Answer:
See the attachment for the appropriate choice.
Step-by-step explanation:
Both equations are in slope-intercept form. Both have a y-intercept of -2, so only a graph where the lines cross at (x, y) = (0, -2) is a viable choice.
In both cases, the inequality requires that values of y be "less than (or equal to)" those described by the line. Hence, the shading will be below both lines.
29.50x - 548= 2,023
Or 2,023= 29.50x - 548
