Answer:
B
Step-by-step explanation:
In the first part for every x, y is the value of x plus 2, while in the second part for every x. y is 5
Use an addition or subtraction formula to find the exact value of the expression, as demonstrated in example 1. tan(105°)
Answer:
Quarters = 10
Dimes = 15
Step-by-step explanation:
d = number of dimes, q = number of quarters
d + q = 25 is the equation for number of coins
0.1d + 0.25q = 4 is the equation for value of coins
First, solve for d in terms of q:
d + q = 25
d = 25 - q
Then substitute that into the other equation:
0.1(25 - q) + 0.25q = 4
2.5 - 0.1q + 0.25q = 4
0.15q = 1.5
q = 10
And back to d = 25 - q, d = 25 - 10 = 15
Check the math:
0.1(15) + 10(0.25) = 1.5 + 2.5 = 4

"horizonally" and "x-coordinate" are very much related.
If you start with a point and move the point horiz., the x-coordinate will change accordingly. If the original point were (2,3) and the point is translated 3 units to the right, then the new x-coord. would be 2+3, or 5: (5,3).
Since percent means parts out of 100 then x/100=x%
the easy way is to do it is to divide 591 by 2364
591/2364=0.25
0.25/1 multiply by 100/100=25/100=25%
the answer is 25%
