No Solution
When you do the substitution method, you would have the x and y variables equal to zero. In systems of equations, the equations are equal with each other.
20x-8y=-5
10x-4y=-4
20x-8y=-5
-2(10x-4y=-4)
20x-8y=-5
-20x+8y=8
The 20x and -20x cancel out
The -8y and 8y also cancel out. Thus leaving -5 and 8
According to system of equations, the equations must be equal. Additionally, -5 does not equal to 8.
Therefore, the answer is no solution.
Answer:
The answer to your question is z = -3
Step-by-step explanation:
Expand 42 = -7(z - 3)
42 = -7z + 21
Simplify 7z = -42 + 21
7z = -21
Clear z z = 
z = -3
All up there are 20 marbles and only 6 of those are chances of winning so we make it into a fraction 6/20 then times 20 by five to get to 100 (what ever we do to the bottom we do to the top) times 6 by five giving you a fraction of 30/100 then divide 30 by 100 giving you 0.30 ANSWER EQUALS = 0.30
The amount of the loan after 11 years is $34,113.53 and the intereest earned is $4,113.53
<h3>How to calculate the compound interest</h3>
The formula for calculating the exponential function is expressed as:

Given the following
- P = 30,000
- r = 0.047
- t = 11 years
- n = 4
Substitute into the formula to have:

Hence the amount of the loan after 11 years is $34,113.53
<h3>
Find the interest earned</h3>
Interest = A - P
Interest = 34,113.53 - 30000
Interest = 4,113.53
Hence the intereest earned is $4,113.53

Answer:
1.5467, 3.348, 3.3487, 3.4897
Step-by-step explanation:
Remember to compare each one number at a time!
For the first number, only one number is 1 while the others are 3 making it the lowest.
Then when comparing 3.348 and 3.3487, it can be implied that there is a 0 at the end of 3.348 because it makes the numbers have the same # of decimal places without changing the value of the number (3.3480). That number is less than 7.
Finally, 3.4897 has a 4 in the tenths place instead of a 3 making it the highest number.
Hope this helps!
