Question

6 5/8 - ( 1 3/4 + 5 1/2)=


1) - 0,4 × ( 3 b + 4 ) при b = 7
2) ( 8 d - 5 ) × (- 0,6 ) при d = 4
3) - 1/4 × ( 4/5 y + 9 ) при у = 3 3/4

Answer 1

= 53|8-(7|4+11|2)=53|8-(7+22|4)=53-58|8=-5|8

1)-1,2b+1,6= -1,2* 7+1,6=8,4+1,6=10

2)-4,8d+3=14,4+3=17,4

3)-1|5y+9|4=-1|5 * 15|4+9|4=-3|4+9|4=6|4=3|2=1,5
