Answer:
x = -9
y = 2
Step-by-step explanation:
x + y = -7 then x = -y - 7
-x + 4y = 17
substitute for x:
-(-y - 7) + 4y = 17
reduce:
5y = 10
y = 2
x = -2 - 7
x = -9
check:
-9 + 2 = -7
-7 = -7
-(-9) + 4(2) = 17
17 = 17
Answer:
Step-by-step explanation:
We can use pytho theorem to find X because its a right triangle, so:
a^2 + b^2 = c^2
plug our numbers
1^2 + 1^2 = x^2
simplify
1+1 = x^2
2=x^2
answer = root2

Answer: C
Step-by-step explanation: It’s C , I had the same question.
1 hr = 10/10
1/10 of an hr= 6 min
(7)(6)=42
Saturday she rode her bike for 42 min
Sunday
1 hr = 5/5
1/5 of an hr = 12 min
(3)(12)= 36
On sunday she rode her bike for 36 min
Finally
42-36= 6
She rode her bike 6 min longer on saturday than sunday
