✔ 最佳答案
(-6/5)÷(3/4)x(3/8)+(-4/15)x3/2 =(-6/5)*(4/3)*3/8+(-2/5)
=(-3/5)+(-2/5)
=-1
1)F=9c/5+32, If c=40
F= 9*40/5+32
F=72+32
F=104
2) N=50+ V/2, If v=4.4
N=50+4.4/2
N=50+2.2
N=52.2
3) M= a(a-1)/2, If a=9
M=9(9-1)/2
M=9*8/2
M=36
4) B=n/3(1-2d), If n=1/2 and d=1/2
B=(1/2)/3[1-2*(1/2)]
B=(1/2)*(1/3)[1-1]
B=(1/6)*1
B=1/6
5) S=5v+2t+3/v+t, If v=6 and t=8
S=5*6+2*8+3/6+8
S=30+16+1/2+8
S=30+16+0.5+8
S=54.5
Hope can help you!~
