Answer:
1,778
Step-by-step explanation:
Let C and S represent the cost and salvage value of Truck B, respectively. Let X represent the number of miles per year that answers the question.
Truck A's cost for 10 years is ...
A = C+600 +(0.06)(2.25)(10X) -(S+200)
Truck B's cost for 10 years is ...
B = C +(0.07)(2.25)(10X) -S
We want to find X such that Truck A's cost is lower, so ...
C -S +1.35X +400 < C -S +1.575X
400 < 0.225X
1777 7/9 < X
1778 miles driven per year (or more) makes Truck A a better option.
0.000000714 is the decimal version, but as a fraction its 5/7,000,000
9514 1404 393
Answer:
no solution
Step-by-step explanation:
Simplifying the given equation, you have ...
-6(x -2) +3x = -3(x +3) +21 . . . . . given
-6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses
-3x +12 = -3x +13 . . . . . . . . . . . . collect terms
0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides
There is no value of x that will make this true.
The equation has NO SOLUTION.
Answer:
B= Surface Area, C=Volume
Step-by-step explanation:
For the cardboard, since it is the outside of the juice box, the surface area is needed. The inside is not needed, so it would not be volume. In a similar way, C can be answered.
