Answer:
x = 61, y = 29
Step-by-step explanation:
29+x = 90
x = 61
x + y = 90
y + 61 = 90
y = 29
To find the difference, we need to subtract the height of the fish from the height of the bird. If we use sea level as 0, then the bird flies at 1,281 feet, and the fish swims at -282 feet.
1,281 - (-282) = <span>1,281 + 282 = 1,563 feet
There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>
Answer:
1) Arithmetic since it decreases by 3 so, -3n + 38.
2) Arithmetic since it decreases by 20 each time, so -20n+17
Step-by-step explanation:
Answer:
there is 60% chance it is blue and 50% its a fantasy one.
Step-by-step explanation:
6 out of 10 = 60%
3 out of 6 or 2 out of four is 50%
Simultaneous Equations
2u + b = $110
4u + 3b = $268
(x2) 4u + 2b = $220
(x1) 4u + 3b = $268
<em />If both the matching coefficients are the same, we subtract equation 2 from equation 1
2b - 3b = -b
$220 - $268 = $-48
-b = -$48
b = $48
If you want to find out what a unicycle costs...
Substitute b = $48 into the first equation
2u + $48 = $110
Balance the equation, whatever happens on one side, happens on the other.
2u + $48 (-$48) = $110 (-$48)
2u = $62
2u(/2) = $62(/2)
u = $31
