Answer:
Step-by-step explanation:
The slope-intercept of 4x-2y=3 is (-3/2) which is -1.5 in decimal form.
The slope-intercept of 3y+x=5 is (5/3) which is 1.666...
Answer:
Option C
Step-by-step explanation:
This is easy!
The ratio in which Adm, Ming and Clinton sold sandwiches = 4:7:3
Number of sandwiches sold by Ming = 91
Let us assume the common ratio to be = x
Then
7x = 91
x = 91/7
= 13
Then
The number of sandwiches sold by Adm = 4 * 13
= 52
The number of sandwiches sold by Clinton = 3 * 13
= 39
So
The total number of sandwiches
sold by Adm, Ming and Clinton = 52 + 91 + 39
= 182.
So a total of 182 sandwiches were sold by Adm, Ming and Clinton.

Answer:
Step-by-step explanation:
The interior angle of the m-gon is ...
m-interior = 180 -360/m
The exterior angle of the k-gon is ...
k-exterior = 360/k
The required relationships are ...
m = 3k
m-interior = 14/3(k-exterior)
Substituting for m, we can write the latter relation as ...
(180 -360/(3k)) = 14/3(360/k)
Multiplying by 3k/180, we have ...
3k -2 = 28
k = (28 +2)/3 = 10
The values of k and m are 10 and 30, respectively.
_____
<em>Check</em>
The interior angle of the m-gon is 180 -360/30 = 168 degrees.
The exterior angle of the k-gon is 360/10 = 36 degrees.
The angle ratio is 168/36 = 14/3 as required.
