Answer:
its the first one
Step-by-step explanation:
Given:
The descriptions and equations. The equations are
To find:
The correct description for each equation and match them.
Solution:
We know that, "+" is used for more and "×" is used for times.
Additive: y is 4 more than x.
Additive: x is 4 more than y.
Multiplicative: y is 4 times x.
Multiplicative: x is 4 times y
Therefore, the correct description for the equation is "Multiplicative: y is 4 times x
" and the correct description for the equation is "Additive: y is 4 more than x.
"
Answer:
190 possibilities.
Step-by-step explanation:
The problem is called 20 choose 2, given by the formula for combinations
C(20,2) = 20! / (2! (20-2)!) = 190
alternatively, we can reason it this way:
there are 20 choices to choose a captain and 19 choices for an alternate captain for a total of 380 ways.
However, there are 20 choices to choose an alternate captain and 19 choices for a captain for a total of 380 ways.
Since we are essentially double counting every choice of the posts, we need to divide 380 by 2 to get 190 ways.
Answer:
Step-by-step explanation:
274.04/34=8.06(21)=169.26
If the problem is 6r•s•4rt•10rst, then the answer is 240•r^3•s^2•t^2.
