Answer:
a = 17, b = 6
Step-by-step explanation:
Sides GF and GH are congruent, so we have ...
GF = GH
30 = 2a -4 . . . . substitute given values
15 = a -2 . . . . . divide by 2
17 = a . . . . . . . . add 2
Sides FJ and HJ are congruent, so we have ...
FJ = HJ
3b +6 = 24 . . . . substitute given values
b +2 = 8 . . . . . . divide by 3
b = 6 . . . . . . . . . subtract 2
The values of a and b are (a, b) = (17, 6).
Answer:
8 statues, with a bit of paint left over
Step-by-step explanation:
Divide the 8/9 liter of paint by the quantity of paint needed per statue, to obtain the number of statues Erin can paint:
8/9 liter 8 10
------------------------- = ----- * ----- statues = 80/9 statues.
1/10 liter / statue 9 1
80/9 statues comes out to 8 8/9 statues. 8 statues can be painted, but Erin will either have to settle for partially painting one more statue or not using up the last remaining bit of paint.
