Answer:

Step-by-step explanation:

1.51 gram to $ 1567.01 = 2.23 gram to $ x

1.51 / 1567.01 = 2.23 / x

cross multiply because this is a proportion

(1.51)(x) = (1567.01)(2.23)

1.51x = 3494.43

x = 3494.43 / 1.51

x = $ 2314.19 <===== what 2.23 grams of gold is worth

==========================

x = first car and y = new car

x = 28,033.51

y = 2x - 301.26

y = 2(28,033.51) - 301.26

y = 56,067.02 - 301.26

y = $ 55,765.76 <====== new car cost

Princeton caught 42 fish this summer, which is 70% of the number of fish his friend Trenton caught.
Mashcka [7]
I hope you actually want to know the number of fishes caught by Trenton the friend of Princeton. Let us write down all the details that are given in the question. These details will help in answering the question.
Number of fishes caught by Princeton = 42
Let us assume the number of fishes caught by Trenton = x
Then
70x/100 = 42
7x/10 = 42
7x = 42 * 10
7x = 420
x = 420/7
  = 60
So the number of fishes caught by Trenton = 60.

Bioshpere: is comprised of all life on earth
Lithosphere: solid earth, or planet
hydrosphere: all of the lakes and water on a planet are involved when talking about its hydrosphere.
atmosphere: the gases encasing earth.

I chose: Atmosphere and Hydrosphere

My Answer: The earths hydrosphere allows for most life on earth to exist including mushrooms requiring moisture in order to grow. The atmosphere not only helps to form the water cycle with the hydrosphere giving moisture to fungi, but also has winds that help mushrooms to reproduce by releasing "spores" into the atmosphere. These spores are blown by the atmosphere helping in germination.
