Answer:
x = -45, y = -40
Step-by-step explanation:
Based on the first clue, we find out that
x + 5 = y
5x = 6y + 15
We can re-write the first equation to x = y - 5.
Therefore, the second equation can also be written as 5(y - 5) = 6y + 15
This can be simplified to 5y - 25 = 6y + 15
We can subtract 6y from each side, and add 25 to each side;
5y - 6y = 15 + 25
Therefore, -y = 40
Therefore y = -40.
Now let's plug this back into the original equation, to get : x + 5 = -40
x=-45
Answer:
No, it is not.
Step-by-step explanation:
It can not be turned into a fraction and isn't repeating with the same number.
Your answer is 5, you use the formula for a pyramid
Answer:
8z+5
Step-by-step explanation:
Let's split the expression into two terms- z and... not z :)
3z+5z=8z
Why? it's just 3+5 with z tacked on the end
14-9=5
simple math :)
put it together to get
8z+5
all done!
lmk if you have any more questions
Answer:
B.
Step-by-step explanation:
Green: y = 1.75x + 4
The slope is 1.75 which is the rate per mile.
Green charges $1.75 per mile.
White:
For 3 miles: $10.50
For 5 miles: $13.50
Difference: $13.50 - $10. 50 = $3.00
The $3.00 difference is for 2 miles.
Rate per mile: $3.00/2 = $1.50
White charges $1.50 per mile
Answer: B.
