Answer: 126cm, 136.5cm, 147cm, 144cm, 100cm
Step-by-step explanation: 5% increase is the same as multiplying by 1.05, and to do it in reverse you divide instead.
120*1.05=126cm
130*1.05=136.5cm
140*1.05=147cm
151.2/1.05=144cm
105/1.05=100cm
Answer:
6 + 3y
Step-by-step explanation:
a + b = b + a
Numbers can be added in any order, and you still get the same answer
She washed 30 plates from 7:30 to 7:35.....so she washed 30 plates in 5 minutes.....30/5 = 6 plates per minute
so if she started washing plates at 7:15 and ended at 7:38...how many plates did she wash....
from 7:15 to 7:38 is 23 minutes...and if she can wash 6 plates per minute, then in 23 minutes, she can wash (23 * 6) = 138 plates <==
the equation...
y = -6x + b...with b being the number of plates she started with and x being the number of minutes and y being the plates she has left to wash...I am not 100% sure on this equation...I am so sorry
Answer:
It would be B (15x + 20x)
