Answer:
15z+13
Step-by-step explanation:
hey! all we have to do is combine like terms.
21z-6z+13
15z+13
there's your answer.
1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5
2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]
3) ab/100
a% of b = (a/100)(b) = ab/100
I think the answer would be D, but I’m not sure.
