You can round 396 to 400 and 71 to 70. then you just multiply them and get 28,000. :))
Answer:
21/45
Step-by-step explanation:
You make the denominator the same and u also multiply the top too and u subtract and thats how u get the answer
2x + y = 10 is y = -2x + 10
4x + 7 = 40
-7 -7
4x = 33
4 4
x = 8.25
y = -2(8.25) + 10
y = -6.5 and x = 8.25
Hope this helps :)
Y=180-69=111
4x+7=y
4x+7=111
4x=111-7
4x=104
X=26
Answer: x=26, y=111
