Answer:
Step-by-step explanation:
What you would want to do is add the $15.75 you would want to add it 5 times
4% Of 75 is 3 so yeah the answer to your question is 3
Problem 12)
You are correct. You solve the system
x+1 = 3y
3x-4 = 5y+1
for x and y to find that x = 5 and y = 2
As a check
x+1 = 3y
5+1 = 3*2
6 = 6 ... true equation
and
3x-4 = 5y+1
3*5-4 = 5*2+1
11 = 11 ... true equation
Both equations are true when (x,y) = (5,2) so the answer is confirmed

Problem 13)
Unfortunately the diagram is cut off so its impossible to say at the moment. Please repost this one. Thank you.
Answer:
24 and yes
Step-by-step explanation:
Here, we want to find the value of x
the side facing the right angle is the side measured 26 and that is the hypotenuse
According to Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
Thus;
26^2 = 10^2 + x^2
x^2= 26^2-10^2
x^2 = 676-100
x^2 = 576
x= √576
x = 24
Yes, they form a pythagorean triple as the square of the two smaller numbers will give the biggest number at all times
