Answer:
B
Step-by-step explanation:
Answer:
the answer is
Step-by-step explanation:
x=1/2y+5---i
4x+3y=-20 ----ii
putting value of x in eqn Ii
4×(1/2×y+5)+3y=-20
2y+5+3y=-20
5y+5=-20
5y=-20-5
5y=-25
y=-25/5
y=-5
putting value in eqn I
x=1/2×-5+5
x=-5/2+5
x=5/2

Answer:
11.5 hours
Step-by-step explanation:
25 pages every 75 minutes (1 1/4)
Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)
230 pages would mean 690 minutes (times the 3 by 230)
690/6 = 11.5
