Answer:
11 cups of dough
Step-by-step explanation:
1 cup x 11 dumplings = 11 cups of dough needed
In form ax + b = c: 2x - 8.4 = 5
Solution to equation: x = 6.7
Step-by-step explanation:
4x - 8.4 = 2x + 5
2x - 8.4 = 5
2x = 13.4
x = 6.7
Answer: 20%
Step-by-step explanation:
If we let the original amount be x, then after increasing it by 25%, we now have 1.25x
To get this back to x, we need to do 1.25x*(something) = x
this gives us that something = 1/1.25 = 0.8
meaning you need to decrease it by 100% - 80% = 20%
Examples :
2/x < 4 ....multiply both sides by x, cancelling it on the left side
2 < 4x ...now divide by 4
2/4 < x
1/2 < x
5/x + 7 > = 12
5/x > = 12 - 7
5/x > = 5 ....multiply by x, cancelling it on the left
5 > = 5x...divide by 5
5/5 > = x
1 > = x
