since there is a bisector that makes the two angles equal. you first need to find x then with x you can add the angles to get the biggest angle witch is RMQ

2x+1 = 4x-9

1=2x-9

10=2x

5=x

x=5

RMQ=2x+1+4x-9

RMQ=2(5)+1+4(5)-9

RMQ=10+1+20-9

RMQ=11+11

RMQ=22

RMQ=16

svlad2 [7]

Answer:

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.

Which of the following expressions could represent how much Leila pays in total for the model?

Step-by-step explanation:

The original price of the dinosaur model is "x" dollars

On top of that, the sales tax is 7% of the original price

Hence,

The total price would be the original amount PLUS the taxed amount

Original Amount = x

Taxed Amount = 7% of x

That is, 7% in decimal multiplied with "x".

7/100 = 0.07

0.07 * x = 0.07x

Total amount = x + 0.07x = 1.07x

The expression for total amount is 1.07x
