Answer:
160 degrees
Step-by-step explanation:
25q + 10d = 425
q + d = 20
First thing's first, picture 4 quarters. Do you know how much these 4 quarters are worth? Obviously, you'd answer one dollar, but take the time to think about how exactly you came up with this answer.
"Well, it's simple," you might think, "Multiply 0.25 by 4."
Similar to this train of thought, the first equation is formulated by doing exactly that. 'q' represents an unknown number of quarters, and 'd' an unknown number of dimes. We use 25q and 10d, because, well, we're multiplying their value by the number of coins. They're equivalent to 425 because the 20 unknown coins make $4.25 (I converted it to cents to get rid of the pesky decimals, but if you want to keep it as dollars that works too).
Because the equation states that there are 20 coins in total, we know that we can make the equation 'q + d = 20' since there are 20 quarters and dimes in total.
Let me know if you need any further explanation :)

Answer:
A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.
If 94 has any other factors other than 1 and itself it is a composite number if it has only 1 and itself then it is prime
2x2 = 4 plus 6x7 = 42 plus 8-3 = 5 x 2 plus 1 = 3
your answer is 59
