Answer:
The equation is c=2n
The constant of proportionality is 2
$18 will buy 9 cups of coffee
Step-by-step explanation:
Cost c=2*n
where c is the number of cups
The constant of proportion is 2
If cost is $18, then
18 = 2n
n = 18/2
n = 9
$18 will purchase 9 cups of coffee
The ANWSER is B hope this helps
Answer + Explanation:
<h3>16.</h3>
sum of opposite two angles = one exterior angle
50° + 20° = d
d = 70°
<h3>17.</h3>
A straight line has total 180° angle.
a + d = 180°
90° + d = 180°
d = 180° - 90°
d = 90°
<h3>18.</h3>
sum of opposite two angles = one exterior angle
52° + 78° = d
d = 130°
<h3>19/20.</h3>
If a = 90° then d = 90°
Then b = 90 - c and c = 90 - b
<h3>21.</h3>
If d = 105°, then c = 105 - b
