Answer:
The answer is 75 miles per hour
Step-by-step explanation:
225÷3=75 ( how many times 3 go into 225)
We can check to see if this answer is correct by multiplying 75 by 3 ( multiply 75 three times)
75×3=225
There for 75 is the correct answer

Manipulate the first equation to
y = 22-7z
Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1
So y = 22-7(1) = 22-7 = 15
y = 15; z = 1
At least 4 means its minimum value is 4 so n≥4
