1) which expression forms an equation with the given expression? 18-4•3=a. 8•4÷4b. 14-11•2c. 3(12-9)d. 12÷3+32) choose the expression that completes the equation 24÷6+20=a. 3(7+1)b. 2(7+10)c. 4(4+3)d. 3(7+7)

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
