Answer:
Option c
Step-by-step explanation:
-7 + (19 + 5) = (-7 + 19) + 5
LHS = -7 + (19+5)
= -7 + 24
= 17
RHS = (-7 + 19) + 5
= 12 + 5
= 17
LHS = RHS
associative property of addition: When three or more numbers are added, the result remains same regardless how the numbers are grouped
Area of rectangle=12x20x8=1920 sq ft
area of triangle=0.5x12x4=24
total sq ft=1920+24=1944
1944 divide by 200=9.72
9.72 round off to nearest whole number =10 gallons
10x$48.00=$480
Answer:
f(x)=x+2.
f(1/3x)=1/3 x+2=(x+6)/3or x/3+2

12x-21y=-42 -----> /3 (divided by 3 )
4x-7y=14 ------ (2)
4x-7y=-2 ------- (1)
how 4x-7y =14 an = -2
and if we
(2)-(1)
0=12
