Answer:

Positive integers have values greater than zero. Negative integers have values less than zero. Zero is neither positive nor negative. The rules of how to work with positive and negative numbers are important because you'll encounter them in daily life, such as in balancing a bank account, calculating weight, or preparing recipes.

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,

pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities vary directly.

Therefore, we have

$b=kw$ , where k is the constant of variation.

Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have

$5=136k\\
\\
k=\frac{5}{136}$

Thus, the constant of variation is $\frac{5}{136}$

Now, we have been given 3.5 bushels of wheat. Hence, we have

$3.5=\frac{5}{136} w\\
\\
w=\frac{136\times 3.5}{5} \\
\\
w=95.2$

Therefore, 3.5 bushels of wheat weigh 95.2 kg

The length of a rectangular deck is 5 times it’s width. If the decks perimeter is 36feet, what is the deck area?

Stolb23 [73]

Answer:

Step-by-step explanation:

P = 2(L+W)

36 = 2(5W + W)

36 = 10W + 2W

36 = 12W

W = 3

5W = 5(3) = 15

15 x 3 = 45
