Answer:
<u>The correct answer is A. 10 - 2</u>
Step-by-step explanation:
1. Let's make all the comparisons for the four alternatives:
A. 3 + 7 > 10 - 2 ⇒ 10 > 8, the comparison is correct because 10 is bigger than 8.
B. 3 + 7 > 9 + 4 ⇒ 10 > 13, the comparison is not correct because 10 is less than 13.
C. 3 + 7 > 7 + 3 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
D. 3 + 7 > 8 + 2 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
<u>The only correct comparison is A. 10 - 2.</u>
Answer:
6 ways
Step-by-step explanation:
The way to solve for this is to use the formula
Combination C (n-1, r-1)
= n = 5 identical fruits
r = 3 bowls
So, we have: 5 - 1 = 4
3 - 1 = 2
= 4!/2! (4-2)!
= 4 × 3 × 2 × 1/(2 × 1 )(2 × 1)
= 6 ways
Answer:
There are 11 four person passengar cars
Step-by-step explanation:
let's call the number of four person cars A , & the number of six person cars B
there are 3 less 6 person cars than 4 people cars which can be written as:
A - 3 = B
there are also 92 total people that can go on max on the whole ride which can be written as:
4A + 6B = 92
Now we need to subsitute in our first equation into the second, so:
4A + 6(A-3) = 92
then distrbute the 6:
4A + 6A - 18 = 92
bring like terms to the same side & consolidate:
4A + 6A = 92 + 18
10A = 110
divide the right by # of A to get a single term :
A = 110/10
A= 11
