Answer:
Step-by-step explanation:
Goven the length of the field = 110m
Width = 80m
The length of the diagonal is expressed using the pythagoras theorem;
d² = l² + w²
d² = 110² + 80²
d² = 12100 + 6400
d² = 18500
d = √18500
d = 136.01
Hence the players have to run 136.01m diagonally
3x + y = 4
step by step explanation
S = Sally
M = Mother
S = M/5 + 10
20 = M/5 + 10
20 - 10 = M/5
10 = M/5
M = 10 * 5
M = 50
----------------
Her mother is 50 yo
-----------------
50 : 5 + 10 = 20
the answer is good
D
You use algebra and solve it for y.
4x-3y=18
3y=4x+18
y=4/3x +6
