Answer:
x=13,y=0
Step-by-step explanation:
We are given a system of equations

For equation 1,square all terms to reduce it
√x²+√y²=169
x+y=13
Make x the subject as required by the question to use substitution method
x=13-y
Plug x=13-y into eqn 2
3(13-y)+2y=39
39-3y+2y=39
39-y=39
y=39-39=0
Plug y=0 into equation 1
x+0=13
x=0
Answer:
3.9 - C
Step-by-step explanation:
This forms a triangle with a base of 2.5 and a height of 3.
Using the Pythagorean Theorem, 2.5^2 + 3^2 = c^2
This gives you the answer 3.91.
It should have 2 solutions
