Answer:
Step-by-step explanation:
let x = number of of hot dogs that 105 people will do
therefore
14 people = 21 hot dogs
105 people = x hot dogs
14 x 105 people = 21 x Xhotdogs
1470 = 21X
divide through by 21
1470/21 = 21X/21
70 = X
X = 70
therefore,
105 people will makev 70 hot dogs
Answer:
Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other
Step-by-step explanation:
Take for instance 2 linear functions, and
If they intersect in some point in the space, say that is
Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)
So, we can compare the two functions and get the following result;
It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.
hope this helps!
Answer: 138
Step-by-step explanation:
(65*2)=130
(4*2)=8
130+8=138
They must split one with the ,2 bros and the other one gets a whole one I think let me check.......
First we are gonna find the 3% of $3000 and take it from the $157.50.
3000 x 0.03 = $90
157.60 - 90 = $67.50
Then we are gonna find the amount that 4.5% of is equal to $67.50.
4.5/100=67.50/x (cross multiply)
4.5x = 67.50x100
4.5x = 6750 (divide both sides by 4.5)
4.5x/4.5 = 6750/4.5
x = 1500
Therefore the amount she earned in sales is $3000 + $1500 = $4500
