Answer:
The car would have traveled 1,018.4 miles in 19 hours because you have to multiply 1 by 19 to get to 19 so you would have to do the same to the miles and 53.6 times 19 is 1,018.4 miles.
Step-by-step explanation:
Let number of quarters in family piggy bank = x
Let number of dimes in family piggy bank = y
Given that "there are 12 times as many dimes are there are quarters". so we can write equation:
y=12x...(i)
Given that " total change is worth $21.75".
We know that 1 quarter = $0.25 and 1 dime = $0.10
So other equation will be :
0.25x+0.10y=21.75...(ii)
Now we just need to solve both equations.
Plug (i) into (ii)
0.25x+0.10y=21.75
0.25x+0.10(12x)=21.75
0.25x+1.2x=21.75
1.45x=21.75
x=15
plug x=15 into (i)
y=12x=12*15=180
Hence final answer is given as:
Number of quarters in family piggy bank = 15
Number of dimes in family piggy bank = 180

Hello there! Given the equation, we can solve through a series of steps:
1. Convert
In this step, we convert the mixed numbers to make them improper:
2 x 4 + 1 = 9, which means -4 1/2 = -9/2
4 x 3 + 3 = 15, which means -3 3/4 = -15/4
2. Multiply
Now that we have the improper fractions, we can multiply accordingly:
(-9/2 • -15/4) = -135/8
3. Simplify
Since we have our result, we can simplify to a mixed number:
-135/8 = 16 7/8
Your final answer is 16 7/8. Hope this helps!
M is your answer, because the tangent intersects the circle at point M.
So M is correct.
