Answer:
31.5 $
Step-by-step explanation:
First lets se how much 1 pound of pasta costs in the store. We do this dividing the price for 8 pounds over those 8 pounds:
12/8 = $1.5 each pound
As 21 pounds are needed:
$1.5 * 21 = $31.5
Answer:
See answers below
Step-by-step explanation:
1. If two parallel lines cut by a transversal, then the two same-side interior angles are equal
2. (4x + 3 )+ (x + 2) = 180
5x + 5 = 180
5x = 175
x = 35
3. one angle = 4(35) +3 = 143°
the other angle = 35 + 2 = 37°
Answer:
- <u><em>Sometimes.</em></u>
Explanation:
The statement is <em>P forward Q is true and q is true, then p is true sometimes always or never.</em>
<em />
That, written using logical symbology, is:
- p → q,
- q is true
- then p is ?
p → q is known as a conditional statement.
When the conditional p → q is true and p is also verified to be true, you must conclude that q is (necessarily) true (else the conditional would be false).
That also means that if q is verified to be false (not true), p must necessarily be false (else the conditional would be false).
Nevertheless, the fact that q is true, does not permit to conclude whether p is true or false: p can be either true or false when you only know that q is true.
Then, you cannot tell that p is true always or never; some times it could be true and others false.
