9t = 27.99
5t = ?
Cross-multiply : 9t? = 139.95t
?=15.55
Answer:
No Solution.
Step-by-step explanation:
2(x-1)-y=-8
y=2x+8
----------------
2x-2-(2x+8)=-8
2x-2-2x-8=-8
2x-2x-2-8=-8
0-2-8=-8
-2-8=-8
-10=-8

Answer:
There are 35 adult dogs and 20 puppies
<em></em>
Step-by-step explanation:
<em>Represent the puppies with P and the Adult dogs with A</em>
Given

Dogs = 55
Required
Determine A and P
First, we need to sum the ratios;



Adult Dogs is then calculated as follows;




Puppies is calculated by subtracting the number of adult dogs from the total



<em>Hence;</em>
<em>There are 35 adult dogs and 20 puppies</em>
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
