She will have about 3 minutes 20 seconds to work on each exercise because 1/3 of an hour is 20 minutes. You can find that by dividing 60 by 3. Next you have to divided 20 by 6. Your answer will be 3.33333333333. So you would get about 3 minutes 20 seconds
Answer:
a = 35
Step-by-step explanation:
5/7a = 25
multiply both sides by 7:
5a = 175
divide by 5:
a = 35
Hope this helps !!!
Answer:
b < -1
Step-by-step explanation:
Step 1: Write inequality
-3(6b - 1) > 18 - 3b
Step 2: Solve for <em>b</em>
<u>Distribute -3:</u> -18b + 3 > 18 - 3b
<u>Add 18b to both sides:</u> 3 > 18 + 15b
<u>Subtract 18 on both sides:</u> -15 > 15b
<u>Divide both sides by 15:</u> -1 > b
<u>Rewrite:</u> b < -1
Answer:
4/pi=w-6/pi
<u>4</u><u> </u><u> </u><u> </u>=<u> </u><u>w</u><u>-</u><u>6</u>
<u>Pi</u><u> </u><u> </u><u> </u><u> </u><u> </u><u>pi</u>
Cross mutiply
Pi(w-6)=4(pi)
Wpi - 6pi =4pi
Collect like terms
Wpi=4pi + 6pi
Wpi =10pi
<u>Divide</u><u> </u><u>both</u><u> </u><u>sides</u><u> </u><u>by</u><u> </u><u>pi</u>
<u>Wpi</u><u> </u>= <u>10pi</u>
Pi pi
W = 10
