Answer:

I hope it helps u

Step-by-step explanation:

Let's solve your system by elimination.

15j+12k=18;5j+4k=6

Multiply the second equation by -3, then add the equations together.

(15j+12k=18)

−3(5j+4k=6)

ludmilkaskok [199]

Answer:

The​ day's high temperature written as degrees Celsius is 25 degrees' Celsius.

Step-by-step explanation:

The​ day's high temperature in St. Louis ,Missouri was recorded as 77 degrees F.

We are supposed to find the​ day's high temperature written as degrees Celsius.

Formula : C=\frac{5}{9}(F-32)

Substitute the value of F is 77 degrees

So,C=\frac{5}{9}(77-32)

C=\frac{5}{9}(45)

C=25

Thus, The​ day's high temperature written as degrees Celsius is 25 degrees' Celsius.
