Answer:

We can rewrite this as $\frac{200x}{x} + \frac{-300}{x}$ .

$\frac{200x}{x}$ simplifies to 200 after eliminating x from the numerator and denominator and $\frac{-300}{x}$ becomes $-\frac{300}{x}$ so the final answer is $200 - \frac{300}{x}$ .

The width of a rectangle is 2 less than twice the length, x. If the perimeter is 44, what is the width?

Butoxors [25]

Take the length as 'x'

Width = 2x - 2

Perimeter = 44 [ Formula = 2(l + w) ]

2 (l + w) = 44

2 (x + 2x - 2) = 44

2 (3x - 2) = 44

6x - 4 = 44

6x = 44 + 4

6x = 48

x = 48/6

<u>x </u><u>=</u><u> </u><u>8</u> => length

Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>

Hope it helps!

one canned juice drink is 25% orange juice ; another is 10% orange juice. how many liters of each should be mixed towing order t

JulijaS [17]

-------------------------------------------------------------------------------------------------
Assumptions
-------------------------------------------------------------------------------------------------
Let x be the amount of 25% orange juice
Let y be the amount of 10% orange juice

-------------------------------------------------------------------------------------------------
There are 15 litres of 13% orange juice
-------------------------------------------------------------------------------------------------
x + y = 15

-------------------------------------------------------------------------------------------------
The 15 litres of juice is 13% orange juice
-------------------------------------------------------------------------------------------------
0.25x + 0.1y = 15 x 0.13
0.25x + 0.1y = 1.95

-------------------------------------------------------------------------------------------------
Rewrite the equations and solve for x and y
-------------------------------------------------------------------------------------------------
x + y = 15 ----------------------- (Equation 1)
0.25x + 0.1y = 1.95 ----------- (Equation 2)

(Equation 1):
x + y = 15
x = 15 - y ----------- (Substitute into Equation 2)

0.25 (15 - y) + 0.1y = 1.95
3.75 - 0.25y + 0.1y = 1.95
0.15y = 1.8
y = 18 ÷ 0.15
y = 12 ------------- (substitute into Equation 1)

x + y = 15
x + 12 = 15
x = 15 - 12
x = 3

x = 3 and y = 12
