Two parallel lines are cut by a transversal and form a pair
Novosadov [1.4K]

Answer:

since alternate exterior angles are congruent, you get:  

6x + 5 = 7x - 4  

subtract 6x from both sides of this equation and add 4 to both sides of this equation to get 5 + 4 = 7x - 6x which results in 9 = x

 

solve for x to get x = 9 degrees.

a computer in Texas cost $420 and the tax is $60 what is the tax rate ? can anyone explain how I get the answer
sertanlavr [38]
If I'm interpreting this question correctly, then you want to know the tax per dollar. In order to find that, you need to find the percentage of $420 that equals $60. So, 

420x = 60
x = 60/420 
x = 0.1429 (rounded) 

So, the tax rate would be this value multiplied by 100%.

0.1429 x 100% = 14.29%
