Answer:
x = 5
Step-by-step explanation:
y = -4x + 5 4x + y = 10
substitute the y in the second equation with
(-4x +5).
4x + (-4x + 5) = 10 then add like terms.
x + 5 = 10 solve for x.
10 - 5 = 5 make sure to check your answer.
5 + 5 = 10

Step-by-step explanation:
To find the answer, use the Pythagorean Theorem.
a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
625 = c^2
25 = c
