Answer:
45 for 5 and 34 for 6.
Step-by-step explanation:
You are just subtracting by 11.
Let h be the price of a hamburger, d be the price of a drink, and f for the prices of fries.
2h+3d=12
4f+3h+5d=15
d=1
this is a system of 3 equations.
Answer:
Step-by-step explanation:
Since I have to assume a is part of the fraction. We will answer assuming /a is replaced with a/12 + 1/3
To write 12/a as a fraction we must multiply with a common denominator. Thus being 3/3.
Now to write 1/3 as a fraction with a common denom we must use a/a.
Then we want to write each expression with a common denominator of a * 3 and multiply by a factor of 1.
Then we want to multiply 1/3 and a/a.
Then we reorder the factors of a *3.
Next, we combine the numerators over the common denom.
FInally, we multiply 12 by 3.
Not sure what the "T" is but if you were trying to solve or factor the parenthetical term:
-4t^2(t-2) is the factored form and the zeros or solutions would be when:
t=0 and 2
If the "T" was a leading coefficient of "t" the above still holds true except:
-4t^3(t-2), but the solutions are the same...
A..Just plus it if not wrong
