Answer:
a rental car agency charges a flat rate fee of $32.00 plus $3.00 per day to rent a certain car
c = 32 + 3d
another agency charges a fee of $30.50 plus $3.25 per day to rent the same car
c = 30.50 + 3.25d
the number of days for which the cost are the same means
32 + 3d = 30.50 + 3.25d
by solving we find d = 6 days
Answer:
Step-by-step explanation:
3ab + 7a² + 2b² - (7a² - 4ab + 2b²) = 3ab + 7a² + 2b² - 7a² + 4ab - 2b²
Now combine like term. Like terms have same variable with same power.
= <u>3ab + 4ab</u> <u>+ 7a² - 7a²</u> + <u>2b² - 2b²</u>
= 7ab
Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.

Answer:
W = -1
Step-by-step explanation:
3W - 8 + 3W = -4 + 5W - 5
combine like terms
6W - 8 = -9 + 5W
subtract 5w on both sides
W - 8 = -9
add 8 on both sides
W = -1
