X+3y = 2

Mathematics
1 answer:
nalin [4]3 years ago
8 0

Answer:

The value of "x" is 5.

Step-by-step explanation:

In order to solve this system of equations, we first have to take the first equation and use it to represent "y" in terms of "x". We do that in the following way...

x + 3y = 2\\3y = 2 - x\\y = \frac{2}{3} - \frac{x}{3}

Now, we need to take the second equation and substitute "y" for the equivalent value in terms of "x". After doing this we will get the following equation, which we can solve to get the value of "x".

4x - 3y = 23\\4x-3(\frac{2}{3} - \frac{x}{3}) = 23\\4x - 2 + x = 23\\5x - 2= 23\\5x = 25\\x = 5

Therefore, the value of "x" is 5.

without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90
yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram

Please help!!! I need an answer!!!!
Nataly [62]

Section A:

3*2^1 = 6

3*2^2=12

12-6 = 6

rate of change = 6

SECTION B:

3*2^3 = 24

3*2^4 = 48

48-24 = 24

rate of change = 24


Part B 24/6 = 4 ( Section B is 4 times greater) because the equation is raised to the x power the lager the x value the greater the rate of change would be
