The values of :
[tex]x = 2[/tex][tex]y = 3[/tex]The given equations are :
[tex]0.4x + 0.3y = 1.7[/tex][tex]0.7x - 0.2y = 0.8[/tex]now, let's multiply both the equations with 10 on both sides.
so, now our equations will be :
[tex]4x + 3y = 17[/tex][tex]7x - 2y = 8[/tex]from Equation second :
[tex]7x - 2y = 8[/tex][tex]2y = 7x - 8[/tex][tex]y = \dfrac{7x - 8}{2} [/tex]now, let's substitute the value of y from here into Equation first.
[tex]4x + 3y = 17[/tex][tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex][tex]4x + \dfrac{21x - 24}{2} = 17[/tex][tex] \dfrac{8x + 21x - 24}{2} = 17[/tex][tex] \dfrac{ 29x - 24 }{2} = 17[/tex][tex]29x - 24 = 34[/tex][tex]29x = 34 + 24[/tex][tex]29x = 58[/tex][tex]x = \dfrac{58}{29} [/tex][tex]x = 2[/tex]here, we got the value of x = 2, let's plug it in equation second to find value of y :
[tex]7x - 2y = 8[/tex][tex]7(2) - 2y = 8[/tex][tex]14 - 2y = 8[/tex][tex]2y = 14 - 8[/tex][tex]2y = 6[/tex][tex]y = \dfrac{6}{2} [/tex][tex]y = 3[/tex]And value of y = 3

This Assignment is bloody confusing. PLEASE HELP
Answers
Step-by-step explanation:
A = Future value of the amount invested
P = principal (amount of money invested) = $9,200
i = interest rate = 6% or 0.06
n = number of compounding periods (it is the number of times the interest is compounded).
For the Interest Rate per Compounding Period column, you'll have to divide the interest rate by its corresponding compounding period (please see the definitions of each compounding periods below). For example, the interest rate per compounding period (compounded annually) = interest rate ÷ number of compounding periods ( [tex]\frac{i}{n}[/tex] ) = 0.06/1 = 0.06 or 6%
For the Number of Compounding Periods column, you'll have to multiply (t ) by the number of compounding periods (n):
t × n = 15 years × 1 = 15
The Compound Interest Formula column is pretty self-explanatory--you'll just have to follow the given formula. You need to make sure that you change the values for i and n for every row.
Compounding periods (n):
compounding annually: n = 1
compounding semiannually: n = 2
compounding quarterly: n = 4
compounding monthly: n = 12
compounding weekly: n = 52
compounding daily: n = 365
You'll have to use these values into your Compound Interest formula.
I will do the 2nd row (semi-annually) for you as a guide, but you'll have to do the rest so that you could familiarize yourself on how to do it.
Interest Rate per Compounding Period = i / n = 0.06/2 = 0.03 or 3%
Number of Compounding Periods = t × n = 15 years × 2 = 30
Compound Interest Formula: [tex]A = 9,200(1 + 0.03)^{30}[/tex]

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books. Which equation models the situation?
Answers
Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95
Since he also paid $8.95 for every book, b would be multiplied by 8.95
All of this will eventually add up to a sum of 47.65

Answers
Answer:
25 and 55
Step-by-step explanation:
Let's call the larger number L and the smaller S
L = 5 + 2×S
And the sum is:
L + S = 80 Subtract S in both sides:
L = 80 - S
Now, substitute this value of L in the first equation:
80 - S = 5 + 2×S Add S in both sides:
80 = 5 + 2×S + S
80 = 5 + 3S Subtract 5 in both sides
75 = 3S Divide both sides by 3
25 = S
We find the value of S, and now we substitute it in the second equation to find the value of L:
L = 80 - 25
L = 55
