8.473 is the correct answer
Answer: D. (-6,2)
Step-by-step explanation:
y = x + 8
2x + y = -10
v
2x + x +8 = -10
x = -6
y = -6 + 8 ( plug in x (-6) )
y = 2
( x, y) = ( -6, 2)
2x+1=27032
2x=27031
x=13515.5
2x+3
=2(13515.5)+3
=27034
Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
Answer:
Step-by-step explanation:
0.3
^ You need to move the three before the decimal place and leave 4 empty digits (0) between

A total of 5 moves.
Each move is equivalent to x, the preceding value, times 10. x * 10
Repeated multiplication times the same factor equates to exponentiation, so for a total of 5 moves, it is notated as 
, giving you an expression of:
