The sum of all exterior angles for every shape is 360 so just divide 360 by the measurement of one exterior angle (18) to get 20
Answer:
x=-3/5y+3
Step-by-step explanation:
Let's solve for x.
5x+3y=15
Step 1: Add -3y to both sides.
5x+3y+−3y=15+−3y
5x=−3y+15
Step 2: Divide both sides by 5.
5x/5 = -3y+15/5
Answer
x=-3/5y+3
Answer:
x = -36, y = 6, z = -6
Step-by-step explanation:
The requirement x/z = -z means x = -z².
The requirement x/y = z means x = yz.
These two requirements together mean yz = -z², or y = -z.
The requirements that z/2 and z/3 are integers mean that z is a multiple of 2·3 = 6. The smallest magnitude non-zero multiple is z=-6 (since we also require z < -z).
Using z=-6, we have x = -z² = -36; y = -(-6) = 6.
For some positive integer n, ...
... x = -36n², y = 6n, z = -6n.
The answer is 8/5.
When multiplying fractions you multiply the top numbers (Numerators) and then the bottom numbers (Denominators).
4 * 6 = 24, 3 * 5 = 15. So we have 24/15. We can simplify this since both 24 and 15 are divisible by 3. Divide both the top and bottom number by 3 to get 24/15 = 8/5.
