答案:A
解释
步骤1:
假设 u = 5,v = 6
t = u × $\frac{v}{2}$ = 5 × $\frac{6}{2}$ = 5 × 3 = 15
第2步:
给定 u = 5, v = 6, t = u × $\frac{v}{2}$ = 15
答案:B
解释
步骤1:
假设 p = 4,q = 12
s = p + $\frac{q}{4}$ = 4 + $\frac{12}{4}$ = 4 + 3 = 7
第2步:
给定 p = 4,q = 12,s = p + $\frac{q}{4}$ = 7
答案:D
解释
步骤1:
假设 m = 2,n = 3
p = 3m + 3n = 3(2) + 3(3) = 6 + 9 = 15
第2步:
假设 m = 2、n = 3、p = 3m + 3n = 15
答案:C
解释
步骤1:
假设 s = 2,t = 2
u = 4s + 3t = 4(2) + 3(2) = 8 + 6 = 14
第2步:
假设 s = 2、t = 2、u = 4s + 3t = 14
答案:B
解释
步骤1:
给定 x = 5,y = 5
z = x ÷ $\frac{y}{5}$ = 5 ÷ $\frac{5}{5}$ = 5 ÷ 1 = 5
第2步:
给定 x = 5, y = 5, z = x ÷ $\frac{y}{5}$ = 5
答案:A
解释
步骤1:
假设 p = 3,q = 5
r = 3p – q = 3(3) – 5 = 9 – 5 = 4
第2步:
假设 p = 3、q = 5、r = 3p – q = 4
答案:C
解释
步骤1:
假设 a = 9,b = 6
c = a − $\frac{b}{2}$ = 9 – $\frac{6}{2}$ = 9 – 3 = 6
第2步:
给定 a = 9, b = 6, c = a − $\frac{b}{2}$ = 6
答案:D
解释
步骤1:
假设 s = 2,t = 2
v = 4s ÷ t = 4(2) ÷ 2 = 8 ÷ 2 = 4
第2步:
假设 s = 2、t = 2、v = 4s ÷ t = 4
答案:B
解释
步骤1:
给定 c = 2,d = 8
b = c × $\frac{d}{2}$ = 2 × $\frac{8}{2}$ = 2 × 4 = 8
第2步:
给定 c = 2, d = 8, b = c × $\frac{d}{2}$ = 8
答案:A
解释
步骤1:
给定 j = 3,k = 2
i = j × 4k = 3 × 4(2) = 3 × 8 = 24
第2步:
假设 j = 3, k = 2, i = j × 4k = 24
