Answer: 12 ÷ 1 3/5
The problem is asking us to find how many days food would last. Since the food shelter uses 1 3/5 each day, the 12 bags of food would be split into 1 3/5 they use each day.
First write what are given from the question
We write "<span>Craig scored 12 points in a game" as
</span>⇒ c = 12 <em>(first equation)</em>
We write "<span>Marla scored twice as many points as Craig but 5 fewer than Nelson scored" as
</span>⇒ m = 2c <em>(second equation)</em>
⇒ m = n - 5 <em>(third equation)</em>
<span>
Second, find the expression for n based on what we write above
</span>From the second and third equation
⇒ m = m
⇒ n - 5 = 2c
Subtitute from the first equation
⇒ n - 5 = 2c
⇒ n - 5 = 2(12)
⇒ n - 5 = 24
This is the expression to find how many nelson scored
n - 5 = 24
<span>
</span>
1/3y + 28 = -5
Subtract 28 from both sides:
1/3y = -33
Multiply both sides by 3:
y = -99
The answer is E) NOTA
Answer:
i think it's letter c. f (n) = 4n-1
Step-by-step explanation:
1x4= 4, 2x4= 8, 3x4= 16, and so on
hope this helps!! :))
Answer:
f(x) = 52
Step-by-step explanation:
f(x) does the same things as y, so when you get your answer, think of it as the value for y when x = - 4
The second thing you should know is that wherever you see an x on the right, you put in - 4
Let x = - 4
y = 2x^2 - 3x + 8
y = 2(-4)^2 - 3(-4) + 8
y = 2*16 - (-12) + 8
y = 32 + 12 + 8
y = 52
Be careful how you hand - 3x when -4 is put in for x. -3(-4) = 12 not - 12
f(-4) = 52
