Answer: 4r = 4
Step-by-step explanation:
Ruth bought 4 rulers and each ruler is to be represented by r. She therefore bought:
= 4r
She bought these for a total of $4.00 so the equation then becomes:
4r = 4.00
Equation representing situation is: 4r = 4
8x + 2 > 34
-2 -2
8x > 32
8x (÷ 8) > 32 (÷ 8)
x > 4
so x can equal any number from 5 and infinity
Hope I helped !!! :)
