Mathematics
1 answer:
Lorico [155]3 years ago
6 0

Answer:

-6125

Step-by-step explanation:

negative 78 squared = -6084

-6084 + 3 - 9 = -6090

-6090 - 5 squared minus 6 minus 4 = --6125

I got confused by "8th" and "a minus" do you mean 3a, and 6a?

What does 101=50-h h means the number 49
ICE Princess25 [194]
Let me see if I understand your question:

101=50-h

this would just be an equation with a variable: this variable is "h". Variable is an unknown value, like a name for "something".

so we could say that 101 equals 50 minus "something" and we call this something "h"

this is what 101=50-h "means"

as it happens, we can find out the value of this h:

we can subtract 50 from both sides of the equation:

101-50=50-50-h
51=-h

and multiply by (-1)
-51=h

so our h is equal to -51.

so...  does not actually mean here 49...

let me know if you have further questions!
