The answer is 80 because you add then subtract
Answer:
D. H = 2.1t + 12
Step-by-step explanation:
Let us assume the t be the time in minutes
And h be the water level
Now before reaching to the equation that need to be used
before this, determine the inches per minute i.e.
= 54 inches - 12 inches
= 42 inches in 20 minutes.
Now for per minute, it would be
= 42 inches ÷ 20 minutes
= 2.1 inches per minute
After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12
So the equation is
H = 2.1t + 12
hence, the last option is correct
The second one is the answer
Answer:
4x -2y + 8z
Step-by-step explanation:
10 / 4 = 4x
-5y / 2.5 = -2y
20z / 2.5 = 8z
resulting in 4x -2y + 8z.
Answer:
A) s/3 +t
Step-by-step explanation:
To represent 1/3 of a number, we can simply divide this number by 3, meaning if s is the number, 1/3 of s would be s/3. Now to add t all we have to do is + t, making our answer s/3 + t
