Part a find ratio a and b if given that 7a=3b 5a+3b=6b a+b=4a a+2b/11=b/3 a+3b/5=a-2b/2 part b if a/3=b/2 what are the following ratios? a: b b: a 5a: 3b a+b/b a+b/5a 3a-3b/a-b if completed all of them. first will be awared brainist and will get 5 stars

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
