Answer:
10w² - 35w + 3w² + 8w - 4w² + 9w
= 10w² + 3w²- 4w² - 35w + 8w + 9w
= 9w²- 18w
= 9( w² - 2w )
For #18
you would divide 3y over 3 witch would cancel out then you would divide 9.5 over 3 and you would get (3.16) i think
Answer:
You can spend 4 days in Los Angeles and 3 days in San Francisco.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=7 (1)
275x+400y=2,300 (2), where:
x is the number of days to visit Los Angeles
y is the number of days to visit San Francisco
First, you can solve for x in (1):
x=7-y (3)
Now, you can replace (3) in (2):
275(7-y)+400y=2,300
1,925-275y+400y=2,300
125y=2,300-1,925
125y=375
y=375/125
y=3
Finally, you can replace the value of y in (3) to find x:
x=7-3
y=4
According to this, the answer is that you can spend 4 days in Los Angeles and 3 days in San Francisco.
