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
U have to substitute in the values of x to get the values of y
answers in order from left to right:
4.5, 4, 3.5, 3, 2.5, 2
ex of solving process:
x+2y=7
(-2)+2y=7
2y=9
y=4.5
