Answer:
80 minutes
Step-by-step explanation:
Rate and Time are inverses of each other
First,
Elise Time = 12
and
Katherine Time = 2 * 12 = 24
Their rates would be (inverses):
Elise Rate = 1/12
Katherine Rate = 1/24
Together their rate is 1/12 + 1/24 = 3/24
Now, the inverse of this rate would be the time it takes to complete 1 bag together, that is:
(3/24) ^ -1 = 24/3 = 8 minutes
So, 10 bags would take them:
8 * 10 = 80 minutes
Answer:
1/ 9^5
Step-by-step explanation:
When dividing exponents with the same base, subtract the exponents
9^2 / 9^7
9 ^ (2-7)
9^ -5
We know that a^ -b = 1/ a^b
1/ 9^5
Answer:
B:subtraction property
Step-by-step explanation:
Answer:
(x+4,y+5)
Step-by-step explanation:
If you look at the differences in the x and y rows t=you can see that x is added 4 each time and y is add 5 each time.
The given equation solved for A is A = (T + 5)/ B
<h3>Solving linear equation</h3>
From the question, we are to solve the given equation for A
To solve the equation for A, we will simply make A the subject of the equation
The given equation is
T = AB - 5
Solving for A
T = AB - 5
Add 5 to both sides of the equation
T + 5 = AB - 5 + 5
T + 5 = AB
Divide both sides of the equation by B
That is,
(T + 5)/B = AB/B
(T + 5)/B = A
∴ A = (T + 5)/ B
Hence, the given equation solved for A is A = (T + 5)/ B
