Answer:
40x+150>=400 i think
Step-by-step explanation:
40x+150>=400
40x>=250
x=6.25
2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2
The complement of 31° is the angle that when added to 31° forms a right angle (90° ).
To find 10,000 more than 6,310, you add; so the answer is 16,310
