Answer:
Cost of 1 goggles = $20
Cost of 1 mask = 15
Step-by-step explanation:
Given:
Cost of 2 goggles and 1 mask = $55
Cost of 1 goggles and 2 mask = $50
Find:
Cost of each goggles and mask
Computation:
Assume;
Cost of 1 goggles = a
Cost of 1 mask = b
So,
2a + b = 55.....EQ1
a + 2b = 50.......EQ2
EQ1 x 2
4a + 2b = 110 ......EQ3
EQ3 - EQ2
3a = 60
a = 20
Cost of 1 goggles = $20
a + 2a = 50
20 + 2b = 50
2b = 30
b = 15
Cost of 1 mask = 15
.

Answer: you don't have a problem writen down or an image up for anyone to see I would love to help but nothing is there to help you with.
Step-by-step explanation:
we know that
<u>Law of detachment </u>is used when you have a conditional statement and another statement that matches the hypothesis of the conditional.
<u>Law of syllogism</u> is used when you have two conditionals and the hypothesis of one matches the conclusion of the other
in this problem we have the law of detachment
<u>the conditional statement is </u>
If a triangle has an angle with a measure more than 90°
<u>the another statement that matches the hypothesis of the conditional</u>
then the triangle is an obtuse triangle
therefore
<u>the answer is</u>
the law of detachment
