Hey there!
We can write this equation, where x is the hourly rate and y is the fixed fee.
4x+y=270
7x+y=420
4x+y=270
-7x-y=-420
-3x=-150
x=50
4(50)+y=270
200+y=270
y=70.
The fixed fee is G. $70.
Let me know if this helps :)
-10 - 5x in standard form.
Standard form is when everything is in order.
Variables go before numerical values, so simply rearrange this expression.
-5x - 10

No. A unit rate would be something like 6 2/3 miles per hour, which is the same speed as above.

Answer:
4a2−4ab+b2
Step-by-step explanation:
(2a−b)2 =(2a+−b)(2a+−b)
=(2a)(2a)+(2a)(−b)+(−b)(2a)+(−b)(−b)
Sooo our equation =4a2−2ab−2ab+b2
