7年级上册作业本答案浙教版1.7年级上册作业本答案浙教版篇一1.(1)am/20(2)(20+3a)2.(1)n-1n+1(2)2n-2，2n+23.解：(1)优惠价为0.8x元.(2)原价为5/4x元.4.解：可多用(a/(b-2)-a/b)天.5.解：(1)图中阴影部分的面积为a2-4×1/2πr2=a2-2πr2.(2)图中阴影部分的面积为ab-2•c2=ab-2c2.6.解：(1)3x，5/2ab，-y，-2t2是单项式.3x的系数为3，次数为1；5/2ab 的系数为5/2，次数为2；-y的系数为-1，次数为1；-2t2的系数为-2，次数为2.(2)a+b，1+x2-3x，3x-1/2，m2-1是多项式.a+b为一次二项式；1+x2-3x为二次三项式；3x-1/2为一次二项式；m2-1为二次三项式.1+x2-3x的常数项为1，3x-1/2的常数项为-1/2，m2-1的常数项为-1.7.解：(1)当x=1/2,y=-2时，2x2-y+2=2×(1/2)2-(-2)+2=2×1/4+2+2=41/2.(2)当x=1/2,y=-2时，(4x-2y)/xy=(4×1/2-2×(-2))/(1/2×(-2))=(2-(-4))/(-1)=6/(-1)=-6.8.解：当a=-8,b=3,c=2,d=-4时，（a-b）-（c-d）=[（-8）-3]-[2-（-4）]=(-11)-6=-17；a-b-c+d=(-8)-3-2+(-4)=-8-3-2-4=-17.所以（a-b）-（c-d）=a-b-c+d.结论为（a-b）-（c-d）=a-b-c+d.9.解：在高出山脚xm的山上温度是（26-0.6/100x)〬C.当x=800时，26-0.6/100x=26-0.6/100×800=26-4.8=21.2〬C，即高出山脚800m的山上温度是21.2〬C.10.解：当n=6时，槽内铅笔总数为(n(n+1))/2=(6×7)/2=21（支）.当n=12时，槽内铅笔总数为(n(n+1))/2=(12×13)/2=78（支）.11.解：(1)y=2.3x+0.2.(2)当x=20时，2.3×20+0.2=46.2(元).(3)由题意可知y=23.2，所以23.2=2.3x+0.2，解得x=10，即若买这种商品花去了23.2元，则买了10件.2.7年级上册作业本答案浙教版篇二第一单元散步1．(1)歧(2)蹲(3)霎(4)粼粼2．(1)信服(2)熬过(3)随意3.(1)②(2)①理由：与上文相衔接，读起来很顺口。
