Lo uses mental math to compute 7 times 92.
she thinks (7 times 90)+(7 times 2). which property does lo use to mentally compute 7 times 92?

Associative property is the answer

* remember to do whats in parenthesis first

(90 x 7) = 630 and (7 x 2) = 14

add them both up

644

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.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
