A)

3t = 7k/13  - 17

3t + 17 = 7k/13

13*(3t + 17) = 7k

7k =  13*(3t + 17)

7k = 39t + 221

k = (39t + 221) / 7

b)

7k = 4k/3t -  11t

11t = 4k/3t - 7k              LCM = 3t

11t =  (4k - 21kt) / 3t

11t*3t = (4k - 21kt)

33t² = k(4 - 21t)

33t² /(4 - 21t)  = k

k =  33t² /(4 - 21t)

I hope this helps.

Which list orders the number from least to greatest​
sineoko [7]

Answer:

Option C

-5, -2, 1, 3

Step-by-step explanation:

to get the list that orders the numbers from the least to the greatest, we need to, first of all, know the smallest and the largest numbers.

The largest number is easy to guess - it is undoubtedly 3.

However, the smallest number may be a bit tricky because we are dealing with negative numbers. When dealing with negative numbers, the numbers with greater magnitudes are actually smaller. This means that -5 is less than -3, which is less than -2, and so on.

Coming back to our question, we can now order the numbers as -5, -2, 1, 3 which is option C

Grant earns $5 for each magazine he sells.Write an equation in two variables showing the relationship between the number pf maga
slega [8]

Answer:

A=5m

Grant will make $60 from selling 12 magazines.

Step-by-step explanation:

Let m represent number of magazine sold and A represent amount of money earned.

We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is 5m dollars.

Now, we will equate total amount earned by Grant with A as:

A=5m

Therefore, our required equation would be A=5m.

To find the amount earned by Grant by selling 12 magazines, we will substitute m=12 in our equation as:

A=5(12)

A=60

Therefore, Grant will make $60 from selling 12 magazines.
