Use the associative property to simplify the expression. 43 + 30 + 70 O A. 43 + 10(3 + 7) = 43 + 10(10) = 143 OB. 43 + (30 + 70) = 43 + 100 = 143 O C. 43 + 30 + 70 = 73 + 70 = 143 O = D. 43 + 70 + 30 = 113 + 30 = 143

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

the answer is 8

step-by-step explanation:

3.14 x 8x8

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

only 10/60 isn't equivalent

hope this : )
