Answer:
store A has a better deal. as you can get 12 soda's for the price of $7.20
Step-by-step explanation:
3.60 x 2 = $7.20
Average rate of change is the slope of two coordinate points or values.
Therefore,
Given values are :
(1960,668) and (1970,760)
Slope = (760 - 668)/(1970 - 1960)
Slope = 92/10
Rate of change will be 9.2 gallons/passenger
Answer:
5 feet tall
Step-by-step explanation:
12 x 5 =60
Hey there!
We know that perimeter is all the sides added up.
70= 2w+2L <== this is the basic equation
We know that the rectangles length is three times as long as it is wide.
So, you know that is is three times the length of the width. So, put 3 times w in as length and times that by two since there are two length sides, and keep width the same. 2w because there are two width sides. Then, solve.
70=2(3w)+2w
70= 6w+2w
70=8w
w=8.75
We can check this by plugging it in to our first equation and seeing if it works. First, we need to multiply 8.75 by 3 to get the value for length.
8.75*3= 26.25
2(26.25)+2(8.75)= 70 <=== it works!
So, the length is 26.25 cm and the width is 8.75 cm.
I hope this helps!

I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2
