If it is $4.00 per gallon then we need to find the price of 7 gallons.
7 * 4.00 = 28
so it costs $28 to travel 350 miles.
no to find the cost per mile, we need to divide.
350 / 28 = 12.5
so the cost to run the car per mile is $12.50
<h3>Answer:</h3>
none of these has "no solution"
<h3>Explanation:</h3>
A. The solution is (8/3, 3)
B. The second equation is -1/2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
C. The solution is (-4, -2)
D. The solution is (4, -2)
E. The second equation is 2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
_____
A system of equations will have "no solution" when it describes parallel lines—lines that do not intersect. In standard form, such equations are recognizable by their different constants. For example,
- 3x -4y = -4
- 3x -4y = 20 . . . . . . 20 is different from -4
have different constants, so the equations describe parallel lines.
We could multiply one of these by -2 and the system would still be "inconsistent"—having no solution.
Answer:
-12.5%
Step-by-step explanation:
The percentage change in your time can be computed using ...
pct change = ((new value)/(old value) -1) × 100%
= (28/32 -1) × 100%
= (0.875 -1) × 100% = -12.5%
The time to finish level 2 decreased by 12.5%.
Answer: part a.) c =2A/d
Part b.) d = 7
Part C The diagonals are each 8
Step-by-step explanation: part b:
35= 10d/2 70= 10d. 7 =d
Part c 32= 2c²
64 = c²
√64 = √c²
c = 8
Eight more than the product of two and a number x
8+2x <== in mathematical form
Eight more= 8+
Product= multiply
number=x
