-99又10/11x22=(-100+1/11)x22=-100x22+1/11x22=-2200+2=-2198
1113.2再答：对了吗
7/13x6/29+6/13x22/29=(7*6+6*22)/(13*29)=(6*29)/(13*29)=6/13
99.99×22.22+33.33×33.34=33.33×3×22.22+33.33×33.34=33.33×66.66+33.33×33.34=33.33×(66.66+33.34)=33.33×
11x22+0.22x3300+330x4.4=11×11×2＋11×0.02×11×300＋11×30×11×0.4=11的平方×【2＋6＋12】=121×20=2410
LINDO程序之中不能用分号和除号所以你写的约束条件的最后两个式子是不对的,同时LINDO程序之中不能有括号!程序如下：max3100x11+3100x12+3100x13+3800x21+3800x
7/13×6/29+6/13x22/29=(7×6+6x22)/(13x29)=(6x29)/(13x29)=6/13
75185.294052再答：👌✌🙏再问：要过程再问：要过程再答：不知道
你写完整你要做什么东西这样我不知道你要干什么再问：恩，我是想求和，刚没说清楚，再答：那你写完整我这里只能告诉你可以用@sum函数写再问：好吧，我知道是sum函数，就是想知道怎么实现循环加法，比如说：(
4.4*（5.5-3.3+2.2）=4.4*4.4=(5-0.6)^2=25-6+0.36=19.36
11x22+0.22x3300+330x4.4=11*22+22*33+66*22=11*22(1+3+6)=242*10=2420
99.99×22.22+33.33×33.34=33.33×3×22.22+33.33×33.34=33.33×66.66+33.33×33.34=33.33×(66.66+33.34)=33.33×
11x22+0.22x3300+330x4.4=2*11*11+2*3*11*11+3*4*11*11=(2+6+12)*11^2=20*121=2420
581x22约等于多少把581看做580
99.99×22.22+33.33×33.34=(99.99÷3)×(22.22×3)+33.33×33.34=33.33×66.66+33.33×33.34=33.33×(66.66+33.34)=
240光年再答：决对正确再答：帮我点下采纳再答：谢了再答：^O^再问：不会吧，我怎么没看出来
=33.3×（6.66+3.34）=333再答：亲，给个好评吧
99.99×22.22+33.33×33.34=(99.99÷3)×(22.22×3)+33.33×33.34=33.33×66.66+33.33×33.34=33.33×(66.66+33.34)=
（1）依题意，得x22−3x＞0，则2-3x＞0，且x≠0解得，x＜23，且x≠0，即当x＜23，且x≠0时，y的值为正数；（2）依题意，得x22−3x＜0，则2-3x＜0，且x≠0解得，x＞23，即
