I think 73 because:
First I did '1,000 + x = 2,450'
Then I got 'x = 1450'
But then 20 can't go into 1450
So I just add another 10 to 1450 an got 1460
1460/20 = 73!
Hope this helps an is correct!!!
Answer:
D
Step-by-step explanation:
4 x^ + 36=0
4x( x + 9) =0 provd
Answer:
x = ( k+c)/5
Step-by-step explanation:
5x - c = k
Add c to each side
5x -c+c = k+c
5x = k+c
Divide by 5
5x/5= ( k+c)/5
x = ( k+c)/5
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
