Answer:
-10p/3+32-3/2^p
Step-by-step explanation:
B. 1.67
m : n = 2 : 1
( x, y ) = ( (1*3 + 2*(-2))/(2+1) ; (1 * (-1) + 2 * 3) /(2 + 1) ) =
= ( (3-4)/3 ; (-1+6)/3 ) 1.67
Answer: b= -5 over 3
Step-by-step explanation:
create the equation 3b + 9 = 4
subtract 9 from each side to isolate the variable
we are left with 3b = -5
to further isolate the variable divide by 3
3b/3 = -5/3
3b divided by 3 is b, which is equal to -5 divided by 3; -5/3
b = -5/3 is your answer
-2 1/2 ÷ 6
= -(5/2) ÷ 6/1
= -(5/2) × 1/6
=-(5/12)
