7+13+1.5=21.5
If he did it again the way back, it's 21.5 times 2.
He went a total of 43 blocks.
Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
Answer: 75 degrees
Step-by-step explanation: supplementary means 180 so you do 180-105 which is 75
I’m pretty sure the answer is 8 inches, mark as brainleist pls :)
