Answer:
No solution
Step-by-step explanation:
-3x + 3y = 4
-x + y = 3
<u>Solve the equation for x:</u>
<u>Move the variable to the right side and change its sign</u>
-x + y = 3
-x = 3 - y
<u>Change the signs on both sides of the equation</u>
-x = 3 - y
x = -3 + y
<u>Substitute the given value of x into the equation -3x + 3y = 4</u>
-3x + 3y = 4
x = -3 + y
-3(-3+y)+3y=4
<u>Solve the equation for y</u>
-3(-3+y)+3y=4
y = 0
There is no solution for y.
And since there's no solution for y, the system has no solution.
Answer:
543.4 liters
Step-by-step explanation:
The conversion 1 gallon is 3.8 liters can be used as the rate.
To convert gallons into liters, multiply the numbers of gallons by the rate, 3.8.
143 gallons X 3.8 = 543.4 liters
Therefore 143 gallons is 543.4 liters.
Answer:
The two in the middle are the negatives and the two that are on the sides are positive.
The invested money by uncle Sammy = $2,300.
Uncle Sammy makes minimum percent = 7 %.
So, let us calculate the minimum amount Uncle Sammy can make to invest $2,300 at 7%.
7% of 2,300 = 0.07 * 2,300 = $161.
Uncle Sammy makes maximum percent = 13 %.
So, let us calculate the maximum amount Uncle Sammy can make to invest $2,300 at 13%.
13% of 2,300 = 0.13 * 2,300 = $299.
Therefore, the $161 - $299 is the range of money uncle Sammy will make if he invests his next paycheck of $2,300.
