Cost of the magazine and a pizza that was bought by Anja = $9.75
Let us assume the cost of the magazine bought by Anja = x dollars
Then
Cost of the pizza bought by Anja is =2x dollars
Then
x + 2x = 9.75
3x = 9.75
x = 9.75/3
= 3.25 dollars
So
The cost of the pizza bought by Anja = 2x
= 2 * 3.25 dollars
= 6.50 dollars
From the above deduction we can easily conclude that the cost of the pizza bought by Anja is $6.50.
Answer:
The answer to your question is -3, 7
Step-by-step explanation:
Data
x + y = 4 ------------ Equation l
7x + 9y = 42 ----------- Equation ll
Process
1.- Solve the system by elimination
- Multiply equation l by -7
-7x - 7y = - 28
7x+9y = 42
2.- Simplify
0 + 2y = 14
3.- Solve for y
y = 14/2
y = 7
4.- Substitute y in equation l to find x
x + 7 = 4
Solve for x
x = 4 - 7
x = -3
Answer:
4x+5y=74
six 5 credit cources and 11 four credit cources
if u substitute in the value its correct
4(11)+5(6)= 44+30 which is 74
and 11 plus 6 is 17 cources so there you go!
