Answer:
$625
Step-by-step explanation:
to find the original divide the sale price by the decreased percentage. 125/%20(or .20)
X is 1/4
2/3 X 1/4 = 1/6 make all have the same bottom number to make it easier
8/12 x 3/12 = 2/12
The combined distance between CD and DE is CE, so...
2x+4 + 6 = x+14 Simplify like terms..
2x + 10 = x + 14 Subtract x from both sides..
x + 10 = 14 Subtract 10 from both sides...
<h2><u><em>
x = 4</em></u></h2>
Proof: 2 (4) + 4 + 6 = 4 + 14
8 + 10 = 18
<em> Check</em>
Answer:
Ax + By = C
A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:
3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.
Or they can look like this:
x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.
Or this:
8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.
And here's one more:
3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!
The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.
Each bicycle gives a profit of around 60 dollars.
2400/60= 40
The store must sell around 40 bicycles every month.
