The system of equations below has no solution 2/3x+5/2y=15 4x+15y=12 which equation could represent a linear combination of the
system
2 answers:
The complete question in the attached figure
we have
(2/3)x+(5/2)y=15 equation (I)
4x+15y=12 equation (2)
multiplying equation (1) by 6
6(2/3)x+6(5/2)y=6(15)--------------------- > 4x+15y=90 equation (3)
Subtracting equation (3) from equation (2) gives
4x+15y=90
4x+15y=12
-----------------
0x+0y=78------------ > 0=78
Therefore, a system of linear equation that has no solution results on two unequal numbers in both sides of the equation.
the answer is the option B) 0=26

Answer:
ranges from 2890 miles to 5780 miles.
Step-by-step explanation:
Let us call the number of miles the car travels, and
the number of gallons of gas that are used, then we have the relationship
<em>(this says the car travels 17 miles for each gallon of gas).</em>
Now, when , we have
and when , we have
So, when goes from 170 to 340,
goes from
to
.
Therefore, when ranges from 170 to 340 gallons, the distance traveled ranges from 2890 to 5780 miles.
