Yes, u would
15x + 25 = 5x + 175...subtract 5x and 25 from both sides
15x - 5x = 175 - 25
10x = 150
x = 150/10
x = 15
In the equation of a circle in the form (x-h)^2 + (y-k)^2 = r^2, (h,k) is the center and r is the radius.
So, the center of the circle is at (-4,2) with radius 6 units.
Answer:
73 dimes and 133 nickels
Step-by-step explanation:
$13.95 = 1395 cents
5n + 10d = 1395 (since each nickel is 5 cents and each dime is 10 cents)
5n = 1395 - 10d (subtract 10d from both sides to solve for n)
n = 279 - 2d
n + d = 206
279 - 2d + d = 206 (substitute n with the previous expression)
279 - d = 206 (add variable d and -2d)
-d = -73 (solve for d and divide both sides by negative 1)
d = 73
n + 73 = 206 (solve for n and subtract both sides by 73)
n = 133
I believe the answer is (7,0) and (1,6). I hope it's correct :)
