Answer:
x = 1.75y + 0.25z
Step-by-step explanation:
Simplifying
4x + -7y = z
Solving
4x + -7y = z
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
4x + -7y + 7y = 7y + z
Combine like terms: -7y + 7y = 0
4x + 0 = 7y + z
4x = 7y + z
Divide each side by '4'.
x = 1.75y + 0.25z
Simplifying
x = 1.75y + 0.25z
Answer:
7x2 + 3y2 - 4x
Step-by-step explanation:
Fermat's little theorem states that
≡a mod p
If we divide both sides by a, then
≡1 mod p
=>
≡1 mod 17
≡1 mod 17
Rewrite
mod 17 as
mod 17
and apply Fermat's little theorem
mod 17
=>
mod 17
So we conclude that
≡1 mod 17

Tax on canned tuna : None
Tax on paper towels : 6.89*6.25/100=0.430625~$0.43
Tax on straws : 0.99*6.25/100=0.061875~$0.06
Tax on batteries : 5.67*6.25/100=0.35475~$0.35
Total taxes : 0.43+0.06+0.35=$0.84
