Hey there! I'm happy to help!
If angles are complementary, they add up to 90 degrees.
This gives us this system of equations.
J=K-18
J+K=90
We plug the value of J into the second equation to solve for K.
K-18+K=90
We combine like terms.
2K-18=90
Add 18 to both sides.
2K=108
Divide both sides by 2.
K=54
J is 18 less than K.
54-18=36
Therefore, angle J is 36 degrees and angle K is 54 degrees.
Have a wonderful day! :D
2 feet = 24 inches. 24 times 15 is 360 inches, or 30 feet.
3 meters = 300 centimeters. 300 times 32 is 9600 centimeters, or 96 feet.
I think you got the choices mixed up a bit, the one with inches is 360, and the one with centimeters is 9600.
Answer:
The base cost of the camera, exclusive of sales tax, is $160.
Step-by-step explanation:
Set up this equation and solve for x, which is the cost of the camera:
$3.20 = $0.02x [0.02 = 2%]
Solve the equation by dividing $3.20 by 0.02. The answer is $160.
All I know or all I understood was both 7 and 8 aren’t functions. Hope this helped
