Answer:
answer = -12
Step-by-step explanation:
substitute y as -3 and z as 4
3(-3) - 2(4) + 5
-9-8+5
-17+5
-12
12,14,16
You reduce similar terms ("n" and numbers) then you just simplify the equation and kind of guess the even numbers that equal 42 based on your answer (12)
First let’s divided 455 by 6.5 to figure out how far he travels in 1 hour which is equal to 70, now let’s do 2100 divided by 70, it will take 30 hours for him to drive 2100 miles.
Y=x/5 divide both sides by 5
Answer: It's being divided by 5. hope this helps
