Answer:
Total tarts = 45
Step-by-step explanation:
Let x be the total tarts
Pineapple tarts = 1/5
So, coconut tarts are 4/5
She gave 1/2 of the coconut tarts to her uncle,
1/2 * 4/5 = 4/10 = 2/5
So, to find x
4/5x - 2/5x = 18
2/5x = 18
2x = 18 x 5
x = 90/2
x = 45
x ⥶ -3
2x - 7 -3x ⥶ 10
-x + 7 ⥶ 10
-x ⥶10 - 7
-x ⥶ 3
5.833
the answer is: -178/x+10
