Answer:
$1.20 Increase
Step-by-step explanation:
18.60/15.5
- 6/2c is the correct solution
collect like terms : 3cx - cx = 2cx
hence 2cx = - 6
dividing both sides by 2c gives x = - 6/2c
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
d. you add up all the sides. opposite sides are equal. the answer is d. 36
Answer:
G. Modus tollens
Step-by-step explanation:
This question used the inference called modus tollens.
Modus tollens is a a valid form of argument that is of this form below:
<em>If S, then T</em>
<em>i</em><em>f not S, then not T.</em>
S = dog doesn't know perpetrator
Not S = dog knows who the perpetrator is
T = the dog barked
Not T = the dog did not bark.
So if we put this into the statement in bold letters, we would have:
The dog doesn't know perpetrator, so it barked.
And,
The dog didn't bark, so it knows the perpetrator.
