Answer:
Quadrant III
Step-by-step explanation:
A penny is worth 1 cents. So, 84 pennies is 84 cents or $0.84
A dime is worth 10 cents, So, 300 dimes is 30 dollars or $30 dollars
$0.84 + $30 = $30.84
84 pennies and 300 dimes is equivalent to 30 dollars and 84 cents.
Answer:
7) BC = 10
8) BD = 20
Step-by-step explanation:
7) The segment addition theorem tells you ...
AB +BC +CD = AD
(3x+2) +(2x+4) +(3x-2) = 28
8x +4 = 28 . . . . collect terms
8x = 24 . . . . . . . subtract 4
x = 3 . . . . . . . . . divide by 8
BC = 2x+4 = 2(3) +4
BC = 10
__
8) AB +BD = AC +CD
(2x -14) +(-7 +3x) = (2x -3) +(9)
5x -21 = 2x +6
3x = 27
x = 9
BD = -7 +3x = -7 +3(9)
BD = 20

Hello,
x= the number
3x= three times the number
seven decreased by three times a number is forty, then:
7-3x=40
-3x=33
