Answer:
r=-29/20
Step-by-step explanation:
because
-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides
witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.
The is answer is definitely D, because he computed the total population of 3,320 in the survey of his targeted people that he specified which was grade school and high school. In order for his computation to work for his market analysis he used the radius of 5m and the 75% he wanted to achieve.
<span>You obtain the solution of a system of equations of wo equations in two variables when both equations meet. This means that both lines of each equations intersect at some point. Based on this information, you have:
1) System of two equations in two variables with no solution:
This is known as "Inconsistent system", where both lines are parallel, which means that never intersect each other. Therefore, there is no solution.
2) </span>System of two equations in two variables with <span>infinitely many solutions:
This is known as "Dependant system". In this type of system both equations have the same line. So, they have i</span>nfinitely many solutions.
Divide 7 by both sides and it should be s=4
D=7 because 12 multiplied by 7 equals 84
