You got 2 types of data $ and %!
Line them up accordingly and cross multiply.

16% is to $38 as
100% is to $x

X= 38•100/16= $237.5 the price before discount

Answer: The price of the supplies before the discount is $237.5.

Step-by-step explanation: Given that a discount of 16% saved Jackie $38 on office supplies.

We are to find the price of the supplies before the discount.

Let $x be the price of the supplies before the discount.

Then, according to the given information, we have

$16\%\times x=38\\\\\\\Rightarrow \dfrac{16}{100}\times x=38\\\\\Rightarrow 16x=3800\\\\\Rightarrow x=\dfrac{3800}{16}\\\\\Rightarrow x=237.5.$

Thus, the price of the supplies before the discount is $237.5.

The weight of Jacob’s backpack is made up of the weight of the contents of the backpack as well as the weight of the backpack it

Dafna11 [192]

If the backpack (b) contains only textbooks (t) and notebooks (n), the total weight of the backpack is:

b+t+n

but notebooks are 4 pounds, so actually:

b+t+4

also, the backpack weights 2 pounds, so the total weight is:

2+t+4 =t+6
now, "Seventy percent of <span> the total weight is textbooks. ", this means that

t=70%(t+6) - this equation can be used to determine the weight of the textbooks!

A wild animal generally stays at least x mi from the edge of a forest. For a rectangular forest preserve that is 2 mi

Butoxors [25]

Answer:

$Area = 4x^2 - 14x + 10$

Step-by-step explanation:

<em>See Attachment for Complete Question</em>

Given

$Width = 5mi$ --- For the forest

$Length = 2mi$ -- --- For the forest

Required

Determine the area of the habitat

Since the distance between the animal's habitat is x mi on both sides;

The length and width of the habitat is:

$Width = 5 - (x + x)$

$Width = 5 - 2x$

$Height = 2 - (x +x)$

$Height = 2 - 2x$

The area is then calculated as follows;

$Area = Width * Height$

$Area = (5 - 2x) * (2 - 2x)$

Expand

$Area = 5(2 - 2x) -2x(2 - 2x)$

Open Brackets

$Area = 10 - 10x - 4x + 4x^2$

$Area = 10 - 14x + 4x^2$

Reorder

$Area = 4x^2 - 14x + 10$

Hence; the required polynomial for the habitat area is:

$Area = 4x^2 - 14x + 10$
