L Using Properties to Multiply and Divide Rational Numbers
Question 5 of 5
Which expression uses the associative property to make it easier to evaluate
14(1/7.2/5
O A. (14.2/5)1/7
O B. 14(2/5.1/7)
O c. 7(1/14.2/5)
D. (14.1/7)2/5

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
