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
Answer:
96 bags of popcorn and 48 pretzels
Step-by-step explanation:
Let
x ----> the number of bags of popcorn sold
y ----> the number of pretzels sold
we know that
2.50x+2y=336 ----> equation A
x=2y ---> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
2.50(2y)+2y=336
5y+2y=336
7y=336
y=48 pretzels
Find the value of x
x=2(48)=96 bags of popcorn
Answer:
997/100
Step-by-step explanation:
Basically, what you need to do is subtract 275 from 425. When you do that, you get 150, so that was the change in her score. I hope this helps! :)
