Hello there!
To start with subtract the membership fee from the total of $21:
$21 - $12 = $9.
Divide what is left by the cost per video rental:
$9/ $1.50 = $6.
In short, she can rent 6 videos.
Hope This Helps You!
Good Luck :)
Answer:
I think may be it is Option 2 (AB)
Let d = Darlene's dog's weight
let l = Leah's dog's weight
d = 5l
d + l = 84
so, 5l + l = 84, which means 6l= 84
so, l = 84/6 = 14d = 5(14) = 70
<span>Darlene's dog = 70 lbs, Leah's dog = 14 lbs</span>
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
Answer:
0.75 days (im a bit unsure but i tried my best, hope this helps :) )
Step-by-step explanation:
If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.
8: 560
x: 525
x= 7.5 (which is considered 7)
Then, find how long it takes to sample 525 samples, when 560 are done in 36 hours;
560: 36
525: x
x= 33.75 (which is considered 34 hours)
The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator
8; 34
15; x
it will become
15:34
8: x
x= 18 hours
Divide by 24 for days hence 0.75 days
