1/3 of remained 2/3 is 2/9. We’ve used 1/3+2/9 = 3/9+2/9 = 5/9. So we’ve used 5/9 and we have 4/9 of the paint
1.5x + 0.2y = 2.68....multiply by 0.3
1.6x + 0.3y = 2.98...multiply by - 0.2
------------------------
0.45x + 0.06y = 0.804 (result of multiplying by 0.3)
- 0.32x - 0.06y = - 0.596 (result of multiplying by - 0.2)
----------------------add
0.13x = 0.208
x = 0.208/0.13
x = 1.6
1.5x + 0.2y = 2.68
1.5(1.6) + 0.2y = 2.68
2.4 + 0.2y = 2.68
0.2y = 2.68 - 2.4
0.2y = 0.28
y = 0.28/0.2
y = 1.4
solution (they intersect at) (1.6,1.4)
Answer:
47.27
Step-by-step explanation:
5.49+5.49+6.25+12.99+1.75+1.75+1.75+1.75=37.22
37.22×.20 for tip=7.44
37.22×.07 for tax=2.61
37.22+7.44+2.61=47.27
Step-by-step explanation:
the answer is second picture because according to the coordinate which is the first number in the bracket is refer to x axis while the number that after comma is for y axis; (x,y)
