![\frac{28}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B28%7D%7B3%7D%20)
Step-by-step explanation:
number 1 equals 8 1/5
number 2 equals 5
number 3 equals 9 1/3
Answer:
b = 3/4
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
3/ 40 = 1/2 b ( 1/5)
Multiply
3/40 = 1/10 b
Multiply each side by 10
10 *3/40 = 10* 1/10 b
3/4 = b
A : B : C = 5 : 8 : 10
A+ B = 5x + 8x = 13x
13x - 10x = 60
3x = 60
x = 20
Total = 5x + 8x + 10x = 23x
23x = 23(20) = 460 <========= answer
The r would be the number 1 because you would have to make the 2 and 10 equal and 5 x 2 equals 10. 1+1=2.
