Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house
True, you would use the ratio of minutes to seconds.
You would have 198,324 pesos. All you have o do is multiply 1,983.24 by 100
minus 4 both sides
square both sides
x+2=4
minus 2
x=2
<span>the answer is
x = 2; not extraneous</span>
