Answer:
aby/2 = c
Step-by-step explanation:
1) ab * y = ab/2c
2) aby/2 = 2c/2
Final answer: aby/2 = c
<span>Premise
1: If a polygon was translated to the right, then its image is
congruent to its pre-image.
In symbols: p => q
Premise 2: If an image is congruent to its
pre-image, then a rigid transformation was performed.
In symbols: q => r
By the law of silogism
(p => q) and (q => r) => q => r
So, the conclusion is that </span><span>if a polygon was translated to the right, then a rigid transformation was performed. <---- answer</span>
1.) The sum(addition) of 21 and 5 times(multiplication) a number f is(=) 61.
f = unknown number/variable [So 21 plus 5f(5 times f) equals 61]
21 + 5f = 61 [21(one-time) + 5f(number x variable) = 61(total)]
2.) Seventeen more(addition) than seven times(multiplication) a number j is(=) 87.
j = unknown number/variable [So 17 plus 7j(7 times j) equals 87]
17 + 7j = 87
3.) n = number of calls
18 + 0.05n = 50.50
[Company charges $18 plus five cents per call(n), and the total charge was $50.50]
4.) s = the number of students
40 + 30s = 220
[Tutor charges $40 plus $30 per student(s), and the total charge was $220]
3. {6,9,15)
for these u have use Pythagoras theorem
