Answer:
André has 8 $5 bills in his piggy bank
Step-by-step explanation:
Let's call the number of $5 bills in André's piggy bank "x" and the number of $10 bills "y."
From the information given, we can create two equations to represent the situation:
André's weekly allowance: $5 per week.
Money earned for mowing the neighbor's yard: $10 per time.
André's total earnings can be represented by the equation:
Total Earnings = 5x (from allowance) + 10y (from mowing the yard)
We also know that the total amount in the piggy bank is $70:
Total Amount = 5x (from $5 bills) + 10y (from $10 bills)
We're also told that André has a total of 11 bills in his piggy bank:
Total Bills = x (number of $5 bills) + y (number of $10 bills) = 11
Now we have a system of two equations with two variables:
5x + 10y = 70
x + y = 11
We can solve this system of equations using substitution or elimination. Let's use the elimination method. First, we can multiply the second equation by 5 to make it easier to eliminate one of the variables:
5x + 10y = 70
5x + 5y = 55
Now, subtract the second equation from the first equation to eliminate x:
(5x + 10y) - (5x + 5y) = 70 - 55
5y = 15
Now, divide both sides by 5 to find the value of y (the number of $10 bills):
5y/5 = 15/5
y = 3
So, André has 3 $10 bills in his piggy bank. Now, we can use this value to find the number of $5 bills using the second equation:
x + 3 = 11
Subtract 3 from both sides:
x = 11 - 3
x = 8
So, André has 8 $5 bills in his piggy bank.

Answer:
u-7 = ?
13u-9=4
13u=13
u=1
1-7=-6
answer is -6
Step-by-step explanation:
To find the value of u - 7, we first solve the equation 13u - 9 = 4 for u. After finding the value of u, we substitute it into the expression u - 7 to get the final answer.
To find the value of u - 7, we first need to solve the equation 13u - 9 = 4 for u. First, we can add 9 to both sides of the equation to isolate 13u. This gives us 13u = 13. Then, we can divide both sides of the equation by 13 to find the value of u. Therefore, u = 1. Finally, we can substitute this value of u into the expression u - 7 to find the final answer. We have 1 - 7 = -6. Therefore, the value of u - 7 is -6.

Answer : 20,400
Explanation : The name itself suggests that it is 204 thousands.
Which means it has 20 thousands 400.
As renaming process involves, the ability to flexibly rename numbers starting with a whole numbers and move through tens, hundreds, thousands, ten thousands, and so on.
This helps us to find that 204 thousands is 20400 as it says it is a thousand digit value and has three digits in it. To qualify to be called as a thousand it needs to have at least 4 digits in it. But, it has 5 digits because it falls under the category of ten thousands range; which means it should be in 5 digits.
Therefore, the answer is 2→Ten thousand 0→Thousand, 4→ hundred 00→Tens .
So, the answer is correct 20,400.
Answer:
$40.74
Step-by-step explanation:
Daniel's bank account interest is $13.58.
Kenneth's bank account interest is 3 times that of Daniel's account interest.
Hence the amount of interest in Kenneth's account shall be = 3 × $13.58
= $40.74
