12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking.
SO here are the data that we need:
=> 8 and ½ miles = 8.5 miles
=> ½ hour = .5 hours or 30 minutes
Now, let’s solve for the unit rate
=> SO in every 30 minutes he bikes around 8.5 miles
=> Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2
=> 8.5 * 2 = 17miles
=> 17 miles / hour
Becasue there are no repeating numbers in the x coordinate
Answer:
the cost for a member to play a round of golf: $95
the cost for a nonmember: $50
Step-by-step explanation:
the cost for a member to play a round of golf: $x
the cost for a nonmember: $y
x+7y=445
x+2y=195
=> y=50, x=95
Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.
