The answer is C.) 33% i believe. Excuse me if i'm wrong!!!!!
The numbers are: 2n and (2n+2)
we can suggest this equation:
4(2n)=2(2n+2)-12
We compute this equation:
8n=4n+4-12
8n-4n=-8
4n=-8
n=-8/4
n=-2
we compute the numbers:
2n=2(-2)=-4
2n+2=-4+2=-2
answer: the numbers are -4 and -2.
Answer:
the possible line of best fit equation is;
y = 10x + 24
Step-by-step explanation:
Here, we want to get the approximate line of best fit
Mathematically, we have the general line of best fit as
y = mx + b
where m is the slope and b is the y-intercept
By joining the given lines, we can see that the y-intercept values fall a little below 30
This means that the possible y-intercept value is 24
Now, to get the slope value, we select any two points and use the slope equation
We can have (3,50) and (6,80)
Using the slope equation;
m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10
The equation is thus;
y = 10x + 24
Hello there! The cost of a cookie is $0.72.
Start by multiplying the cost of lunch by 5 and subtract that from the total to get rid of the cost of lunch.
$1.85 x 5 = $9.25
$20 - $9.25 = $10.75
So, there were FIVE students and each bough THREE cookies. To find the cost for each cookie, first divide the total spent on cookies by 5 to get what each student spent on cookies, then by 3 to see how much each cookie cost.
$10.75/5 = $2.15
$2.15/3 = 0.716666667, which can be rounded to $0.72.
I hope this helps and have a great rest of your day!
