Let Q = quarters and D = dimes
There are a total of 1202 coins, so we have to add the quarters and dimes together to get this.
Q + D = 1202
Quarters have a value of 25 cents or 0.25, dimes have a value of 10 cents or 0.10. The combination of the amount of quarters and their respective value and the amount of dimes and their respective value equate to $123.50.
0.25Q + 0.10D = 123.50
Put the two equations together. Your system of equations is:
Q + D = 1202
0.25Q + 0.10D = 123.50
Answer: 78.5
Step-by-step explanation: Assuming you use 3.14 for pi, then 5^2 times 3.14 equals to 78.5. If you use the real number for pi, then it is going to be 78.54/

Answer:
Step-by-step explanation:
Given that:
Ken's prediction temperature for April 7C.
His prediction for May is 2C higher than April.
He attempts to use the number line to solve the problem.
On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.
So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.
