Answer:
AX : XB as AB : AC
AX = 5
XB = 4
AC = 6
AB = x
Step-by-step explanation:
5 : 4 as to x : 6
ratios can also be written as fractions...
5/4 = x/6 ..now we have a proportion...so we cross multiply
(4)(x) = (5)(6)
4x = 30
x = 30/4
x = 15/2 <==== AB = 15/2
That would be about 4 pounds
It is 78 because you can draw a transversal with the line that 79 is on, and 79+23+x=180. so 180-79-23=78 therefore 78=x
understand?
