20+24-56 First use Distributive Property
44-56 Next do Addition
-12 Then Subtract
Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.
If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.
Good luck, and feel free to ask with any questions!
18,000. When the place before the number you are trying to round to is less that 5, that round down. If its is 5 or more, then round up.
The finance Charge would be $140. you would multiply 18 by 80 and then add the 130 and take that number and subtract the 1,430
