Answer:
I help u after my online class
X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]
Here is the solution of the given problem above.
Given that the estimated cost of the Hummer is $28,000, and that she invests $12,000 with a 6% rate compounded semiannually. Semiannually, that would be twice a year, so it is the rate every 6 months. Let's get the 6% of $12,000 and it would be $720. Therefore, she will pay a total of $13,440 in a year. Hope this answer helps.
Answer:
for brand a= $8 per/kg and brand b=$5 per/kg
Step-by-step explanation:
Let A be the cost per kg. of brand a
Let B be the cost per kg. of brand b
forming the equation: (wt. * cost + wt. * cost = wt. * cost)
4A + 6B = 10(6.20)
------(1)
2A + 8B = 10(5.60)
------(2)
lets find out the values of A and B by solving above equations.
(1)=>
put this value in eq(2)
(2)=>
= 5 ---> ($5 per/kg for B)
now for A,
=8 ---> ($8 per/kg for A)
