<span>Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8.
Simplify Q - [R + S] - T.
Q-(R+S)-T
=</span>7m + 3n - (11 - 2m + n + 5 ) - (-m - 3n + 8)
=7m+2m+m + 3n-n+3n -11-5-8
=10m+5n-24
Answer:
The solution is (-2, 0)
Step-by-step explanation:
Re-write -2x=-y+4 x=-2 in column form:
x=-2
-2x=-y+4
Next, substitute -2 for x in the second equation:
-2(-2) = -y + 4, or:
4 = -y + 4. Thus, y must be 0.
The solution is (-2, 0)
Answer:
12s+24
Step-by-step explanation:
Answer:
The answer is 10
Step-by-step explanation:
If 1 female sockeye lays 10^3
x female sockeyes lay 10^4
Cross multiply
10^3x=10^4×1
10^3x=10^4
Divide both sides by 10^3
x=10
Therefore 10 sockeyes will lay 10^4
