Answer:
-3
Step-by-step explanation:
7+15+2x=16
22+2x=16
2x=16-22
2x=-6
x=-6/2
x=-3
Pineapple tarts = 4/9
Coconut tarts = 1 - 4/9 = 5/9
gave 1/2 of the pineapple tarts
1/2 x 4/9 = 2/9
Pineapple tarts left = 4/9 - 2/9 = 2/9
gave 2/5 of the coconut tarts
2/5 x 5/9 = 2/9
Coconut tarts left = 2/5 - 2/9 = 8/45
Tarts left = 2/9 + 8/45 = 2/5
2/5 = 60 tarts
1/5 = 60 ÷ 2 = 30 tarts
5/5 = 30 x 5 = 150 tarts
He baked 150 tarts
Answer:
m = -10
Step-by-step explanation:
2.1m - 1.3m = -8
Solve the left side
We have
0.8m = -8
Divide both sides by 0.8 to isolate m
0.8m/0.8 = -8/0.8
m = -10
