67.65 + 57.93 = 125.58
200.00 - 125.58 = $74.42 change back
Answer:yes
Step-by-step explanation: the answer does represent a function because if you were to put points in the line wherever, and connect them by drawing a line vertically, it would not cross two points.
Answer:
Step-by-step explanation:
1) A perfect square is a whole number which is a product of a smaller whole number and itself. Examples of perfect squares are
4(2 × 2)
9(3 × 3)
16(4 × 4)
25(5 × 5)
36(6 × 6)
2) Square root of 4x² is 2x(product of square root of 4 and square root of x²)
3) square of 25 is 5
4) 4x² + 20x + 25
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 4
b = 20
c = 25
Therefore,
x = [- 20 ± √(20² - 4 × 4 × 25)]/2 × 4
x = [- 20 ± √(400 - 400)]/8
x = [- 20 ± 0]/8
x = - 20/8
x = - 2.5
Write and solve an equation of ratios:
oil 8 x
---- = ---- = -----------
vin 5 7 liters
Then 5x = 56, and x = 56/5 liters (of vinegar)
Answer:
29.3
Step-by-step explanation:
4x+12+5x+3x-4=360
Add the X's up & move the numbers w/out factors (X's) to the 360 side. This will look like 12x=352
Then, you divide each by 12, leaving you with x=29.3
Might be wrong, let me know and I will rework it.
