相关知识点: 试题来源: 解析 C If a=4c, c=re, and a=5e, then substituting the second equation into the first equation gives a=4re. Since a=4re=5e and e≠q0, the coefficients of e must be equal, so 4r=5 and r=54.反馈 收藏 ...
p2×q2×r=36. What is the value of r?( ) A.2 B.5 C.7 D.9相关知识点: 试题来源: 解析 D Knowing that p=1, q=2 and p2×q2×r=36, we can substitute the letters p and q for the numbers they represent. So 12×22×r=1×4×r=36 and hence r=36÷(1×4)=36÷4=9...
