Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
Answer:
5-8% of the weight
Step-by-step explanation:
The dog needs to lose a weight within the values 9-15 pounds
To answer this question, what we just need to do is to know the percentage of 185 pounds that is 9 and the percentage of 185 pounds that is 15
The percentage decrease can be calculated using the formula;
(difference)/old value * 100%
For the 9 pound loss, we have ;
9/185 * 100% = 4.86 which is approximately 5%
For the 15 pound loss, we have;
15/185 * 100% = 8.11% which is approximately 8%
Thus, the dog is losing between 5-8% of its weight
Answer:
A.
Step-by-step explanation:
Given
Required
Determine the coordinates of C
Since, point D divides line AB in ratio, 5 : 3;
We start by calculating the coordinates of D;
This is done as follows;
Where
<em />
<em>Since AC is vertical</em>
<em>Then, Point C has the same x coordinate as A</em>
<em />
<em />
<em />
<em>Similarly;</em>
<em>Since CD is horizontal</em>
<em>Then, Point C has the same y coordinate as D</em>
<em />
<em />
<em />
Hence,
Answer:
Step-by-step explanation:
2(10)+1(n)=31
20+n=31
n=31-20
n=11
Since the highest possible value for n is 9, there is no way to make 31 if 2 is in the tens column.
