First, 47.7-45 to get price increase by tax for I which is 2.7. next divide 2.7 by 45 and multiply that by 100 to get a sales tax of 6%. Next 37.7-35 is once again 2.7. divide 2.7/35 and multiply times 100 to get a sales tax of 7.7 for T. T=7.7% and I=6% so since 7.7>6, therefore Tennessee has a greater sales tax then Iowa
Answer:
Cost price=100%
Step-by-step explanation:
x is 
Step-by-step explanation:
Let us revise some rules of exponents
∵ 
- Factorize 27 and 9
∵ 27 = 3 × 3 × 3
∴ 27 = 3³
∵ 9 = 3 × 3
∴ 9 = 3²
Substitute them in the equation
∴ 
- Use the third rule to simplify each side
∴ 
- Use the fourth rule
∵ The bases of the two sides are equal
∴ Their exponents are equal
∴ 3x - 3 = 6x - 14
- Subtract 6x from both sides
∴ -3x - 3 = -14
- Add 3 to both sides
∴ -3x = -11
Divide both sides by -3
∴ x = 
x is

Answer:
y=11
Step-by-step explanation:
Solve the system by substitution by setting the equations equal to each other.
y = 5x+6
y = x+10
It becomes 5x+6 = x+10. Solve for x using inverse operations.
5x+6 = x+10
4x+6 = 10
4x = 4
x=1
Substitute x=1 into one equation to find y.
y = x+10
y = 1 +10
y=11
