2x + 5y = 26....multiply by 3
3x + 4y = 26...multiply by -2
------------------
6x + 15y = 78 (result of multiplying by 3)
-6x - 8y = - 52 (result of multiplying by -2)
-----------------add
7y = 26
y = 26/7 (or 3 5/7)
2x + 5y = 26
2x + 5(26/7) = 26
2x + 130/7 = 26
2x = 26 - 130/7
2x = 182/7 - 130/7
2x = 52/7
x = 52/7 * 1/2
x = 52/14 which reduces to 26/7 (or 1 5/7)
solution is : (26/7, 26/7)
There would be 3. The first one would be with the 4 different types of bread. The second level would have the 3 types of meats branching off from each of the types of bread. The third level would have the 4 different types of cheeses branching off from the each of the different types of meat. Hope this helps!
Answer:
$64.36
Step-by-step explanation:
12% percent of %79.70 is %9.56 and there is a 12% discount so you will subtract $9.56 from %79.70 and you will get $70.14. Now we need 8.25% of %70.14 and now you have $64.36.
I hope this helps.
im pretty sure you dont need exponents for this bud
3x-x-4x+4x
2x+0
2x
