Answer:
B
Step-by-step explanation:
A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.
C is missing many combinations, it only has 4
D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option
We can use the process of elimination to conclude the answer is B.
Answer:
C
Step-by-step explanation:
We need to use the distributive property to expand this.
The property is:
a(b+c) = ab + ac
So, the part " -3(2b+1) " will becomes:
-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3
So, the problem becomes:
-2b -3(2b+1) = -2b -6b -3
Now, we add like terms:
-2b - 6b - 3
(-2-6)b - 3
-8b - 3
This is the correct answer, answer choice C
Answer:
he will ride 81 miles in 5 hrs
Step-by-step explanation:
if he rides 18 miles in 2hrs then multiply 18x4 which is 72
then for the last hour split 18 in half which is 9.
then 72 + 9= 81 miles in 5 hrs
Number of adults' tickets (x): $7.50x + $4.00(500 - x) = $3,312.50 $7.50x + $2,000.00 - $4.00x = $3,312.50 $3.50x = $1,312.50 x = 375
No. of children's tickets (500 - x): = 500 - 375 = 125
Answer: 375 adults' tickets, 125 children's tickets
Proof (Receipts totaled $3,312.50): = (375 tickets * $7.50) + (125 tickets * $4.00) = $2,812.50 + $500.00 = $3,312.50
