Answer:
-4a²+4a³
Step-by-step explanation:
3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
Answer:
x > 4
Step-by-step explanation:
Because x is greater than 4
X
--- × 56 =18
100
56x = 18×100
× = 18 × 100
- - - - - - -
56
X = 32.14%
