Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5
I got the answer right, I just took the test: (going from left to right)
Fish+Bird= 6
Bird+Not fish= 8
Total= 14
Fish+Not bird= 19
Not fish+Not bird= 22
Total= 41
(Now going down the column)
Fish total= 25
Not fish total= 30
Total+Total= 55
Standard form of a line is Y=mX+b
where m is slope
4x+2y=-6
2y=-4x-6
y=- 2x - 6
m= - 2 and y intercept is b=-6
