Selling Price = 400+24
Selling Price = Rs. 424
Answer:
23.5
Step-by-step explanation:
x = 4 ; y = 5
x² + y³ = 4² + 5³ = 16 + 125 = 141
2 + x = 2 + 4 = 6
141 ÷ 6 = 23.5

Answer:
a=45 b=65
Step-by-step explanation:
You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above
