The answer is A.
hope this helps!
2^3 is equivalent because if you count the number of twos there are in the parentheses its 3.
Answer:
4/2+ 8/2+20/5+20/5+48/5+42/4
12/2+88/5+42/4
(120+ 352+210)/20= 682/20= 341 x 1/10=34.1
210 because 7th graders washed 12 cars, 8th graders washed 14 cars, 6th graders washed 16 cars. Added all together and multiplied by 5, it equals 210
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
