3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
Let
x-------> bags of <span>popcorn
</span>y-------> bags of hotdogs
we know that
2.50x+3y=200-------> equation 1
x=2y--------> equation 2
substitute 2 in 1
2.50*[2y]+3y=200--------> 5y+3y=200------> 8y=200-----> y=200/8
y=25
x=2y-----> x=2*25-----> x=50
the answer is
50 bags of popcorn
25 bags of hotdogs<span />
Answer:
Their best investment when they retire in 40 years would be option B.
Step-by-step explanation:
Ragai and Carly invest the $1000 received for their wedding for 40 years.
From the diagram,
In option A, the initial investment do not increase at a constant rate yearly.
In option B, the amount invested increase by $75 yearly.
In option C, the yearly increase does not have a steady value.
In option D, the amount invested increases by a n + consecutive odd values yearly. Where n is the increase of the previous year.
Their best investment when they retire in 40 years would be option B because it would yield the highest profit.
Lets name the largest number as x
smallest number is half the largest , therefore its x/2 = 0.5x
then middle number is 3/4 the largest , therefore its 3/4x = 0.75x
the sum of the three numbers are 162
the three numbers added are
x + 0.5x + 0.75x = 162
2.25 x = 162
x = 72
the largest number is 72
then middle number 0.75 x = 0.75 x 72 = 54
smallest number is 0.5x = 0.5 x 72 = 36
answer is - 36,54,72
The increase is $984 and the new price is $18,875
