Step-by-step explanation:
Answer C: -125p^12 z^18 u^3
Step-by-step explanation:
It should be c C: -125p^12 z^18 u^3 if its wrong sowwy
2x-y=8...(1)
x+y=7....(2)
from (2)
y=7-x....(3)
put (3) into (1)
2x-(7-x)=8
2x-7+x=8
2x+x=8+7
3x=15
x=5.....(4)
put (4) into (2)
x+y=7
5+y=7
y=7-5
y=2
Hope it helps c:
Irrational numbers cannot be represented by a ratio of two integers.
All whole numbers, however, can. This can be done by placing the number over 1. For example 0/1, 34/1, 173635278/1.
Answer:
Step-by-step explanation:
given system :
y=-2x+6 ........(1)
3y-x+3=23.........(2)
Substitute y = -2x+6 into (2) and solve for x :
3( -2x+6) - x +3 = 23
- 6x +18 - x +3 =23
- 7x = 2
x =- 2/7
Substitute : x into (1) : y = -2 (-2/7)+6 = 46/7
