Answer:
10 n equals 6
Step-by-step explanation:
Why? Because that has nothing to do with the problem and no solution for 3/5.
x 20
------ = -------
100 125
(The percentage x saved is equal to 20 out of 120) Cross multiply:
125x = 20(100)
125x = 2000
Divide both sides by 125
x = 16%
Answer:
(4, 5)
Step-by-step explanation:
y = 2x - 3
y = 7 - 0.5x
y is already isolated on both equations, set them equal to each other:
2x - 3 = 7 - 0.5x
add 3 to both sides:
2x = 10 - 0.5x
add 0.5x to both sides:
2.5x = 10
divide by 2.5:
x = 4
plug in 4 for x on either equation and solve for y:
y = 2(4) - 3
y = 8 - 3
y = 5

Answer:




Step-by-step explanation:
The equation needs to be rearranged in terms of one trigonometric function:





The tangent function has positive values in the 1st and 3rd Quadrants. Then, the solutions are:
