Answer:
A and E
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
2/5 x - 1/7 x = 36
14/35 x - 5/35x = 36
9x / 35 = 36
x = 35*36 / 9
x = 35*4 = 140 (answer).
F(-x) = 2/-x/ + 3(-x) = 2/x/ - 3x;
First find the common denominator
5/8=25/40
2/5=16/40
3/4=30/40
Next you can cross multiply
25/40=x/10 pounds
16/40=x/10 pounds
30/40=x/10 pounds
First
25(10)/40= 6.25 pounds
16(10)/40= 4pounds
30(10)/40= 7.5 pounds
These are the amounts that were left in the bag
10-6.25=3.75
10-4=6
10-7.5=2.5
3.75+6+2.5= 12.25
All together they put 12.25 pounds of soil in the flower bed
