3 to a 8 with 5 hope this helps
Answer:
Step-by-step explanation:
x + 3y = 24.....multiply by -1
5x + 3y = 36
------------------
-x - 3y = -24 (result of multiplying by -1)
5x + 3y = 36
------------------add
4x = 12
x = 12/4
x = 3 <=======
x + 3y = 24
3 + 3y = 24
3y = 24 - 3
3y = 21
y = 21/3
y = 7 <========
Answer:
clockwise
Step-by-step explanation:
Conventionally, positive angles in the Cartesian coordinate plane are measured counterclockwise from the +x axis. Rotation in the negative direction is the opposite of that, so is clockwise.
Answer:
Option c
Step-by-step explanation:
We assume that the angle is in the first quadrant.
Observe the attached image.
if 
So:
By definition:
So:
adjacent side = 3
hypotenuse = 5.
Observe the attached image
We find the opposite side "x" using the Pythagorean theorem.
Then, for the angle u:
49 kms : 7 tanks
divide both sides by 7
equals
7 kms : 1 tank
